Angel

In Abrahamic religious traditions (such as Judaism, Christianity, and Islam) and some sects of other belief-systems like Hinduism and Buddhism, an angel is a heavenly supernatural or spiritual being. In monotheistic belief-systems, such beings are under service of the supreme deity (i.e. God).

Abrahamic religions often depict angels as benevolent celestial intermediaries between God and humanity. Other roles include protectors and guides for humans, such as guardian angels and servants of God. Abrahamic religions describe angelic hierarchies, which vary by religion and sect. Some angels have specific names (such as Gabriel or Michael) or titles (such as seraph or archangel). Malevolent angels are often believed to have been expelled from Heaven and called fallen angels. In many such religions, the Devil (or devils) are identified with such angels.

Angels in art are often identified with bird wings, halos, and divine light. They are usually shaped like humans of extraordinary beauty, though this is not always the case—sometimes, they can be portrayed in a frightening, inhuman manner.

Etymology
The word angel arrives in modern English from Old English engel (with a hard g) and the Old French angele. Both of these derive from Late Latin angelus, which in turn was borrowed from Late Greek ἄγγελος angelos (literally "messenger"). Τhe word's earliest form is Mycenaean a-ke-ro, attested in Linear B syllabic script. According to the Dutch linguist R. S. P. Beekes, ángelos itself may be "an Oriental loan, like ἄγγαρος (ángaros, 'Persian mounted courier')."

The rendering of ángelos is the Septuagint's default translation of the Biblical Hebrew term malʼākh, denoting simply "messenger" without connoting its nature. In the Latin Vulgate, this meaning becomes bifurcated: when malʼākh or ángelos is supposed to denote a human messenger, words like nuntius or legatus are applied. If the word refers to some supernatural being, the word angelus appears. Such differentiation has been taken over by later vernacular translations of the Bible, early Christian and Jewish exegetes and eventually modern scholars.

Background
The concept of angels is historically best to be understood from different ideas of the concept of God throughout history. In polytheistic and animistic worldviews, supernatural powers (i.e. deities, spirits, daemons, etc.) were assigned to different natural phenomena. Within a monotheistic framework, these powers were reconsidered to be servants of the supreme deity, turning autonomous supernatural beings into "angels".

By that, are supernatural powers controlling or influencing humanities' perception of the world, including natural phenomena and humans, ultimately under control of a supreme God. Prominent angels, such as Michael and Gabriel, reflect a connection to the Chief Semitic deity El. Even "bad" angels such as Satan, Samael, Iblis etc., can be understood as an operating force within the nature of humans, as responsible for selfish tendencies.

The idea of angels in early Hebrew scripture as supernatural agents is absent. Instead, the Hebrew deity intervenes in human affairs, mostly by means of punishment. Only in later thought of post-exilic and prophetic writings, the Biblical deity is conceptualized as distant and more merciful, his interventions replaced by the idea of angels. However, such angels still carry out the gruesome attributes of God and can be both benevolent and malevolent. The notion of angels as embodiment of good emerges only under influence of Zoroastrianism, in which the Devil is conceived as the principle of evil, with a hosts of demons, in battle with the holy entities (Aməša Spəṇta) created by Ahura Mazda (principle of good).

Influence of dualistic tendencies and replacement of divine powers by angels is evident from the Qumram writings. In the Angelic Liturgy, the Hebrew term elim (deities, heavenly powers) is used for angelic beings and not for God. The War Scroll speaks about angels of light fighting against demonic beings of darkness.

Zoroastrianism
In Zoroastrianism there are different angel-like figures. For example, each person has one guardian angel, called Fravashi. They patronize human beings and other creatures, and also manifest God's energy. The Amesha Spentas have often been regarded as angels, although there is no direct reference to them conveying messages, but are rather emanations of Ahura Mazda ("Wise Lord", God); they initially appeared in an abstract fashion and then later became personalized, associated with various aspects of creation.

Judaism
In Judaism, angels ( mal’āḵ; "messenger"), are understood through interpretation of the Tanakh and in a long tradition as supernatural beings who stand by God in heaven, but are strictly to be distinguished from God (YHWH) and are subordinate to him. Occasionally, they can show selected people God's will and instructions. In the Jewish tradition they are also inferior to humans since they have no will of their own and are able to carry out only one divine command.

Hebrew Bible
The Torah uses the Hebrew terms מלאך אלהים (mal'āk̠ 'ĕlōhîm; "messenger of God"), מלאך יהוה (mal'āk̠ Yahweh; "messenger of the Lord"), בני אלהים (bənē 'ĕlōhîm; "sons of God") and הקודשים (haqqôd̠əšîm; "the holy ones") to refer to beings traditionally interpreted as angels. Later texts use other terms, such as העליונים (hā'elyônîm; "the upper ones").

The term 'מלאך' ('mal'āk̠') is also used in other books of the Hebrew Bible. In the early stages of Hebrew writings, the term refers to human messengers, not to supernatural entities. A human messenger might be a prophet or priest, such as Malachi, "my messenger"; the Greek superscription in the Septuagint translation states the Book of Malachi was written "by the hand of his messenger" ἀγγέλου (angélu). Examples of a supernatural messenger are the "Malak YHWH", who is either a messenger from God, an aspect of God (such as the logos), or God himself as the messenger (the "theophanic angel.")

Michael D. Coogan notes that it is only in the late books that the terms "come to mean the benevolent semi-divine beings familiar from later mythology and art." Daniel is the biblical book to refer to individual angels by name, mentioning Gabriel in Daniel 9:21 and Michael in Daniel 10:13. These angels are part of Daniel's apocalyptic visions and are an important part of apocalyptic literature.

In Daniel 7, Daniel receives a dream-vision from God. [...] As Daniel watches, the Ancient of Days takes his seat on the throne of heaven and sits in judgement in the midst of the heavenly court [...] an [angel] like a son of man approaches the Ancient One in the clouds of heaven and is given everlasting kingship.

Coogan explains the development of this concept of angels: "In the postexilic period, with the development of explicit monotheism, these divine beings—the 'sons of God' who were members of the Divine Council—were in effect demoted to what are now known as 'angels', understood as beings created by God, but immortal and thus superior to humans." This conception of angels is best understood in contrast to demons and is often thought to be "influenced by the ancient Persian religious tradition of Zoroastrianism, which viewed the world as a battleground between forces of good and forces of evil, between light and darkness." One of these is hāššāṭān, a figure depicted in (among other places) the Book of Job.

Rabbinic Judaism
According to Rabbinic Judaism, the angels have no bodies, but are eternally living creatures created out of fire. The Babylonian Talmud reads as "The Torah was not given to ministering angels." (לא נתנה תורה למלאכי השרת) usually understood as a concession to human's imperfection, in contrast to the angels. Thus, they occasionally appear in Midrashim as competition with humans. The angels as heavenly beings, strictly following the laws of God, become jealous of God's affection for man. Humans, by following the Torah, in prayer, by resisting evil instincts (yetzer hara) and by teshuva, are preferred to the flawless angels. As a result, they are also inferior to humans in the Jewish tradition. In the Midrash, the plural of El (Elohim) used in Genesis in relation to the creation of human beings is explained by the presence of angels: God therefore consulted with the angels, but made the final decision alone. This story serves as an example, teaching that the powerful should also consult with the weak. God's own final decision highlights God's undisputable omnipotence.

In post-Biblical Judaism, certain angels took on particular significance and developed unique personalities and roles. Although these archangels were believed to rank among the heavenly host, no systematic hierarchy ever developed. Metatron is considered one of the highest of the angels in Merkabah and Kabbalah mysticism and often serves as a scribe; he is briefly mentioned in the Talmud and figures prominently in Merkabah mystical texts. Michael, who serves as a warrior and advocate for Israel, is looked upon particularly fondly. Gabriel is mentioned in the Book of Daniel and briefly in the Talmud, as well as in many Merkabah mystical texts. There is no evidence in Judaism for the worship of angels, but there is evidence for the invocation and sometimes even conjuration of angels.

Philo of Alexandria identifies the angel with the Logos inasmuch as the angel is the immaterial voice of God. The angel is something different from God himself, but is conceived as God's instrument.

"Four classes of ministering angels minister and utter praise before the Holy One, blessed be He: the first camp (led by) Michael on His right, the second camp (led by) Gabriel on His left, the third camp (led by) Uriel before Him, and the fourth camp (led by) Raphael behind Him; and the Shekhinah of the Holy One, blessed be He, is in the centre. He is sitting on a throne high and exalted"

Later interpretations
According to Kabbalah, there are four worlds and our world is the last world: the world of action (Assiyah). Angels exist in the worlds above as a 'task' of God. They are an extension of God to produce effects in this world. After an angel has completed its task, it ceases to exist. The angel is in effect the task. This is derived from the book of Genesis when Abraham meets with three angels and Lot meets with two. The task of one of the angels was to inform Sara and Abraham of their coming child. The other two were to save Lot and to destroy Sodom and Gomorrah.

Jewish philosopher Maimonides explained his view of angels in his Guide for the Perplexed II:4 and II "... This leads Aristotle in turn to the demonstrated fact that God, glory and majesty to Him, does not do things by direct contact. God burns things by means of fire; fire is moved by the motion of the sphere; the sphere is moved by means of a disembodied intellect, these intellects being the 'angels which are near to Him', through whose mediation the spheres move ... thus totally disembodied minds exist which emanate from God and are the intermediaries between God and all the bodies [objects] here in this world."Maimonides had a neo-Aristotelian interpretation of the Bible. Maimonides writes that to the wise man, one sees that what the Bible and Talmud refer to as "angels" are actually allusions to the various laws of nature; they are the principles by which the physical universe operates."For all forces are angels! How blind, how perniciously blind are the naive?! If you told someone who purports to be a sage of Israel that the Deity sends an angel who enters a woman's womb and there forms an embryo, he would think this a miracle and accept it as a mark of the majesty and power of the Deity, despite the fact that he believes an angel to be a body of fire one third the size of the entire world. All this, he thinks, is possible for God. But if you tell him that God placed in the sperm the power of forming and demarcating these organs, and that this is the angel, or that all forms are produced by the Active Intellect; that here is the angel, the 'vice-regent of the world' constantly mentioned by the sages, then he will recoil. – Guide for the Perplexed II:4"

Christianity


In the early stage, the Christian concept of an angel characterized the angel as a 'messenger' of God. The word "angel" can be drawn to the term or role of a "messenger" throughout the Bible in both old and new testaments - (Hebrews 1:14) calls them "ministering [or serving] spirits", sent by God to aid the "heirs of salvation". Later came identification of individual angelic messengers: Gabriel, Michael, Raphael, and Uriel. Then, in the space of slightly over two centuries (from the 3rd to the 5th) the image of angels took on definite characteristics both in theology and in art. Ellen Muehlberger has argued that in Late Antiquity, angels were conceived of as one type of being among many, whose primary purpose was to guard and to guide Christians.

Bible
Angels are represented throughout Bibles as spiritual beings which are intermediate between God and humanity: "For thou hast made him [man] a little lower than the angels, and hast crowned him with glory and honour". Christians, based on Psalms and Genesis 2:1, believe that angels were the first beings created by God before the creation of Earth. Greek translations of the Hebrew Bible refer to intermediary beings as angels, instead of daimons, thus giving raise to a distinction between demons and angels. In the Old Testament, both benevolent and fierce angels are mentioned, but never called demons. The symmetry lies between angels sent by God, and intermediary spirits of foreign deities, not in good and evil deeds.

In the New Testament, the existence of angels, just like that of demons, is taken for granted. They can intervene and intercede on behalf of humans. Angels protect the righteous. They dwell in the heavens, act as God's warriors and worship God. In the parable of the Rich man and Lazarus, angels behave as psychopomps. The Resurrection of Jesus features angels, telling the woman that Jesus is no longer in the tomb, but has risen from the dead.

Interaction with humans
Forget not to show love unto strangers: for thereby some have entertained angels unawares.—

According to Jesus' statement, angels of Heaven don't marry (,, and ).

Three separate cases of angelic interaction deal with the births of John the Baptist and Jesus. In (Luke 1:11), an angel appears to Zechariah to inform him that he will have a child despite his old age, thus proclaiming the birth of John the Baptist. In Luke 1:26, Gabriel visits Mary in the Annunciation to foretell the birth of Jesus. Angels proclaim the birth of Jesus in the Adoration of the shepherds in Luke 2:10.

According to Matthew 4:11, after Jesus spent 40 days in the desert, "...the Devil left him and, behold, angels came and ministered to him." In Luke 22:43 an angel comforts Jesus during the Agony in the Garden. In Matthew 28:5 an angel speaks at the empty tomb, following the Resurrection of Jesus and the rolling back of the stone by angels.

In 1851 Pope Pius IX approved the Chaplet of Saint Michael based on the 1751 reported private revelation from archangel Michael to the Carmelite nun Antonia d'Astonac. In a biography of Gemma Galgani written by Germanus Ruoppolo, Galgani stated that she had spoken with her guardian angel.

Pope John Paul II emphasized the role of angels in Catholic teachings in his 1986 address titled "Angels Participate In History Of Salvation", in which he suggested that modern mentality should come to see the importance of angels.

According to the Vatican's Congregation for Divine Worship and the Discipline of the Sacraments, "The practice of assigning names to the Holy Angels should be discouraged, except in the cases of Gabriel, Raphael and Michael whose names are contained in Holy Scripture."

Theology
According to Augustine of Hippo, the term 'angel' refers to "the name of their office, not [...] their nature", as they are pure spirits who act as messengers, clarifying: "If you seek the name of their nature, it is 'spirit'; if you seek the name of their office, it is 'angel': from what they are, 'spirit', from what they do, 'angel'." Gregory of Nazianzus thought that angels were made as "spirits" and "flames of fire", following Hebrews 1, and that they can be identified with the "thrones, dominions, rulers and authorities" of Colossians 1.

By the late 4th century, the Church Fathers agreed that there were different categories of angels, with appropriate missions and activities assigned to them. There was, however, some disagreement regarding the nature of angels. Some argued that angels had physical bodies, while some maintained that they were entirely spiritual. Some theologians had proposed that angels were not divine but on the level of immaterial beings subordinate to the Trinity. The resolution of this Trinitarian dispute included the development of doctrine about angels.

Forty Gospel Homilies by Pope Gregory I (c. 540 – 12 March 604) noted angels and archangels. The Fourth Lateran Council's (1215) Firmiter credimus decree (issued against the Albigenses) declared that the angels were created beings and that men were created after them. The First Vatican Council (1869) repeated this declaration in Dei Filius, the "Dogmatic constitution on the Catholic faith".

In the Middle Ages, theologians had to address Augustine's ideas of "angelic knowledge", as set out in De Genesi ad litteram, which he divided into "morning" knowledge, knowledge of Creation before it is created derived from direct access to the Word of God, and "evening" knowledge, knowledge of Creation derived from perceiving it after it has been created. Thomas Aquinas (13th century) related angels to Aristotle's metaphysics in his Summa contra Gentiles, Summa Theologica, the 8th question of Quaestiones Disputatae de Veritate, and in De substantiis separatis, a treatise on angelology.

Aquinas varied significantly from the Augustinian view in two major respects: angels were not created in an initial state of bliss, and only beatified angels have "morning" knowledge. In other words: angels have an angelic nature, but in their natural states have no access to Divine "morning" knowledge of Creation, which they only gain with supernatural assistance. This was Aquinas' most original contribution to Christian angelology. Although angels have greater knowledge than men, they are not omniscient, as Matthew 24:36 points out.

According to the Summa Theologica, angels were created instantaneously by God in a state of grace in the Empyrean Heaven (LXI. 4) at the same time when he created all the contents of the corporeal world (LXI. 3). They are pure spirits whose life consists in knowledge and love. Being bodiless, their knowledge is intellectual and not through senses (LIV. 5). Differently from humans, their knowledge is not acquired from the exterior world (having acquired all knowledge they would ever receive in the moment of their creation); moreover they attain to the truth of a thing at a single glance without need of reasoning (LV. a; LVIII. 3,4). They know all that passes in the external world (LV. 2) and the totality of creatures, but they don't know human secret thoughts that depends on human free will and thereby are not necessarily linked up with external events (LVII. 4). They don't know also the future unless God reveals it to them (LVII. 3).

According to Aquinas, angels are the closest creatures to God. Therefore, like God, they are constituted by pure form without matter. While they do not have a physical composition of matter and form (called ilemorphysm), they possess the metaphysical composition of act (the act of being ) and potency (their finite essence, yet without being ). Each angel is a species which a unique individual belongs to; angels differ one from another by way of their unique and irrepetible form. In other words, form - and not matter - is their principle of individuation.

The New Church (Swedenborgianism)
The New Church denominations that arose from the writings of theologian Emanuel Swedenborg have distinct ideas about angels and the spiritual world in which they dwell. Adherents believe that all angels are in human form with a spiritual body, and are not just minds without form. There are different orders of angels according to the three heavens, and each angel dwells in one of innumerable societies of angels. Such a society of angels can appear as one angel as a whole.

All angels originate from the human race, and there is not one angel in heaven who first did not live in a material body. Moreover, all children who die not only enter heaven but eventually become angels. The life of angels is that of usefulness, and their functions are so many that they cannot be enumerated. However each angel will enter a service according to the use that they had performed in their earthly life. Names of angels, such as Michael, Gabriel, and Raphael, signify a particular angelic function rather than an individual being.

While living in one's body an individual has conjunction with heaven through the angels, and with each person, there are at least two evil spirits and two angels. Temptation or pains of conscience originates from a conflict between evil spirits and angels. Due to man's sinful nature it is dangerous to have open direct communication with angels and they can only be seen when one's spiritual sight has been opened. Thus from moment to moment angels attempt to lead each person to what is good tacitly using the person's own thoughts.

Latter Day Saints
The Latter Day Saint movement views angels as the messengers of God. They are sent to mankind to deliver messages, minister to humanity, teach doctrines of salvation, call mankind to repentance, give priesthood keys, save individuals in perilous times, and guide humankind.

Latter Day Saints believe that angels either are the spirits of humans who are deceased or who have yet to be born, or are humans who have been resurrected or translated and have physical bodies of flesh and bones. Joseph Smith taught that "there are no angels who minister to this earth but those that do belong or have belonged to it." As such, Latter Day Saints also believe that Adam, the first man, was and is now the archangel Michael,  and that Gabriel lived on the earth as Noah. Likewise the Angel Moroni first lived in a pre-Columbian American civilization as the 5th-century prophet-warrior named Moroni.

Smith described his first angelic encounter in the following manner: "While I was thus in the act of calling upon God, I discovered a light appearing in my room, which continued to increase until the room was lighter than at noonday, when immediately a personage appeared at my bedside, standing in the air, for his feet did not touch the floor.

He had on a loose robe of most exquisite whiteness. It was a whiteness beyond anything earthly I had ever seen; nor do I believe that any earthly thing could be made to appear so exceedingly white and brilliant ...

Not only was his robe exceedingly white, but his whole person was glorious beyond description, and his countenance truly like lightning. The room was exceedingly light, but not so very bright as immediately around his person. When I first looked upon him, I was afraid; but the fear soon left me."

Most angelic visitations in the early Latter Day Saint movement were witnessed by Smith and Oliver Cowdery, who both said (prior to the establishment of the church in 1830) they had been visited by the prophet Moroni, John the Baptist, and the apostles Peter, James, and John. Later, after the dedication of the Kirtland Temple, Smith and Cowdery said they had been visited by Jesus, and subsequently by Moses, Elias, and Elijah.

Others who said they received a visit by an angel include the other two of the Three Witnesses: David Whitmer and Martin Harris. Many other Latter Day Saints, both in the early and modern church, have said they had seen angels, although Smith posited that, except in extenuating circumstances such as the restoration, mortals teach mortals, spirits teach spirits, and resurrected beings teach other resurrected beings.

Islam


Belief in angels is fundamental to Islam. The Quranic word for angel (ملاك ) derives either from Malaka, meaning "he controlled", due to their power to govern different affairs assigned to them, or from the root either from ʼ-l-k, l-ʼ-k or m-l-k with the broad meaning of a "messenger", just like its counterparts in Hebrew (malʾákh) and Greek (angelos). Unlike their Hebrew counterpart, the term is exclusively used for heavenly spirits of the divine world, but not for human messengers. The Quran refers to both angelic and human messengers as "rasul" instead.

The Quran is the principal source for the Islamic concept of angels. Some of them, such as Gabriel and Michael, are mentioned by name in the Quran, others are only referred to by their function. Most Muslim theologians, such as al-Suyuti, based on a hadith stating that the angels have been created through the light (Nūr), depict angels as entities consisting of substance, in contrast to philosophers who argued for angels being disembodied spirits. Additionally, angels are thought to be endowed with reason and be subject to God's tests. Al-Maturidi (853–944 CE) states that the inhabitants of heaven were tested by adorenments, just as humans and jinn on earth were tested, pointing at Sūrat al-Kahf [Q. 18:7] When angels fail their tests, they might end up on earth, such as Harut and Marut. If the devils (šayāṭīn) have been angels once or form a separate type of creature from the beginning, is discussed in Islamic tradition. Contrary to popular belief, angels are never described as agents of revelation in the Quran, although interpretation credits Gabriel with that. Angels are not limited to benevolent tasks, but can also carry out grim orders. Not demons, but angels are tasked to guard and punish sinners in hell.

Angels play a significant role in Mi'raj literature, where Muhammad encounters several angels during his journey through the heavens. Further angels have often been featured in Islamic eschatology, Islamic theology and Islamic philosophy. Individual angels are further evoked in exorcism rites, with their names engraved in talismans or amulets to call upon their powers.

Classical period
Islamic theology usually distinguishes between three types of invisible creatures: angels (malāʾikah), djinn, and devils (šayāṭīn). Islamic theologian al-Ghazali (c. 1058 – 1111) divides human nature into four domains, each representing another type of creature: animals, beasts, devils and angels. Reconciling the literal meaning (Ẓāhir) with the Avicennan cosmology of falsafa of angels, he identified angels with the "celestial intellects" or "immaterial souls". Angels, made from light (Nūr) and thus associated with reason ('aql), represent the intellectual capacity of a human and the ability to bound the devilish qualities from within. By that, Ghazali does not deny the literal reality of angels, but rejects that they could be perceived directly.

Although belief in angels remains one of Six Articles of Faith in Islam, one can not find a dogmatic angelology in Islamic tradition. However, theologians generally distinguish between the angels in heaven, fully absorbed in the ma'rifa (knowledge) of God, and the messengers (rasūl) who carry out divine decrees between heaven and earth. Others add a third group of angels, and categorize angels into İlliyyûn Mukarrebûn (those around God's throne), Mudabbirât (carrying the laws of nature), and Rasūl (messengers). Al-Baydawi based this divide into two groups on Quranic verses: angels who are self-immersed in knowledge of "the Truth" (al-Haqq), based on "they laud night and day, they never wane" (21:29), they are the "highmost" and "angels brought near" and those who are the executors of commands, based on "they do not disobey Allah in what He commanded them but they do what they are commanded" (66:6), who are the administers of the command of heaven to earth.

Modern and Contemporary movements
Some modern scholars have emphasized a metaphorical reinterpretation of the concept of angels.

Salafism and Wahhabism generally emphasize a literal interpretation of angels against modernistic interpretations, as for example, suggested by Nasr Abu Zayd. Simultaneously, many traditional materials regarding angels accepted during the Classical period are often disregarded by Wahhabis and Salafis. The Muslim Brotherhood scholars Sayyid Qutb and Umar Sulaiman Al-Ashqar reject much established material during earlier periods, for example, the story of Harut and Marut or calling the Angel of Death Azrail. Sulayman Ashqar not only rejects the traditional material itself, but also disapproves of previous scholars who used such reports.

Iconography
In Islam, just like in Judaism and Christianity, angels are often represented in anthropomorphic forms combined with supernatural images, such as wings, being of great size or wearing heavenly articles. The Quran describes them as "messengers with wings—two, or three, or four: He [God] adds to Creation as He pleases..." The 13th century book Ajā'ib al-makhlūqāt wa gharā'ib al-mawjūdāt (The Wonders of Creation) by Zakariya al-Qazwini describes Islamic angelology, and is often illustrated with many images of angels. The angels are typically depicted with bright, vivid colors, giving them unusual liveliness and other-worldly translucence. While some angels are referred to as "Guardians of the Kingdom of God," others are associated with hell. An undated manuscript of The Wonders of Creation from the Bavarian State Library in Munich includes depictions of angels both alone and alongside humans and animals. Angels are also illustrated in Timurid and Ottoman manuscripts, such as The Timurid Book of the Prophet Muhammad's Ascension and the Siyer-i Nebi.

Baháʼí faith
In his Kitáb-i-Íqán Baháʼu'lláh, founder of the Baháʼí Faith, describes angels as people who "have consumed, with the fire of the love of God, all human traits and limitations", and have "clothed themselves" with angelic attributes and have become "endowed with the attributes of the spiritual". ʻAbdu'l-Bahá describes angels as the "confirmations of God and His celestial powers" and as "blessed beings who have severed all ties with this nether world" and "been released from the chains of self", and "revealers of God's abounding grace". The Baháʼí writings also refer to the Concourse on High, an angelic host, and the Maid of Heaven of Baháʼu'lláh's vision.

"I raised my hand another time, and bared one of Her breasts that had been hidden beneath Her gown. Then the firmament was illumined by the radiance of its light, contingent beings were made resplendent by its appearance and effulgence, and by its rays, infinite numbers of suns dawned forth, as though they trekked through heavens that were without beginning or end. I became bewildered at the pen of God's handiwork, and at what it had inscribed upon Her temple. It was as though She had appeared with a body of light in the forms of the spirit, as though She moved upon the earth of essence in the substance of manifestation. I noticed that the houris had poked their heads out of their rooms and were suspended in the air above Her. They grew perplexed at Her appearance and Her beauty and were entranced by the raptures of Her song. Praise be to Her creator, fashioner, and maker--to the one Who made Her manifest.

Then she nearly swooned within herself, and with all her being she sought to inhale My fragrance. She opened Her lips, and the rays of light dawned forth from Her teeth, as though the pearls of the cause had appeared from Her treasures and Her shells.

She asked, 'Who art Thou?'

I said, 'A servant of God and the son of his maidservant.'"

Philosophy of religion
In Ancient Greek philosophy, there is no significant distinction made between good and evil spirits. Under Iranian influence, the sublunary sphere was traced to inspiring angels. Philo of Alexandria already identified the Neo-Platonic interpretation of daemons as angels. The daemons were thought to be intermediary between the supernatural and earthly realm, interpreted by Philo as the Greek term for angels.

In the commentaries of Proclus (4th century) on the Timaeus of Plato, Proclus uses the terminology of "angelic" (aggelikos) and "angel" (aggelos) in relation to metaphysical beings. According to Aristotle, just as there is a Prime Mover, so too, must there be spiritual secondary movers.

Ibn Sina, who drew upon the emanation cosmology of al-Farabi, developed an angelological hierarchy of Intellects, which are created by "the One". Therefore, the first creation by God was the supreme archangel followed by other archangels, who are identified with lower Intellects. From these Intellects again, emanated lower angels or "moving spheres", from which in turn, emanated other Intellects until it reaches the Intellect, which reigns over the souls. The tenth Intellect is responsible for bringing material forms into being and illuminating the minds.

Graeco-Roman world
The Greek magical papyri, a set of texts forming into a completed grimoire that date somewhere between 100 BC and 400 AD, also list the names of the angels found in monotheistic religions, but they are presented as deities.

Gnosticism
Numerous references to angels present themselves in the Nag Hammadi Library, in which they both appear as malevolent servants of the Demiurge and innocent associates of the aeons.

Hermetic Qabalah
According to the Kabbalah as described by the Golden Dawn there are ten archangels, each commanding one of the choirs of angels and corresponding to one of the Sephirot. It is similar to the Jewish angelic hierarchy.

Theosophy
In the teachings of the Theosophical Society, Devas are regarded as living either in the atmospheres of the planets of the Solar System (Planetary Angels) or inside the Sun (Solar Angels) and they help to guide the operation of the processes of nature such as the process of evolution and the growth of plants; their appearance is reputedly like colored flames about the size of a human. It is believed by Theosophists that devas can be observed when the third eye is activated. Some (but not most) devas originally incarnated as human beings.

It is believed by Theosophists that nature spirits, elementals (gnomes, undines, sylphs, and salamanders), and fairies also can be observed when the third eye is activated. It is maintained by Theosophists that these less evolutionarily developed beings have never been previously incarnated as humans; they are regarded as being on a separate line of spiritual evolution called the "deva evolution"; eventually, as their souls advance as they reincarnate, it is believed they will incarnate as devas.

It is asserted by Theosophists that all of the above-mentioned beings possess etheric bodies that are composed of etheric matter, a type of matter finer and more pure that is composed of smaller particles than ordinary physical plane matter.

Yazidism
In Yazidism, there are seven Divine Beings (often called 'angels' in the literature) who were created by God prior to the creation of this world. God appointed Tawûsî Melek as their leader and assigned all of the world's affairs to these seven Divine Beings. These Divine Beings are referred to as Tawûsî Melek, Melek Şemsedîn, Melek Nasirdîn, Melek Fexredîn, Melek Sicadîn, Melek Şêxsin and Melek Şêxûbekir.

In art
According to mainstream Christian theology, angels are wholly spiritual beings and therefore do not eat, excrete or have sex, and have no gender. Although their different roles, such as warriors for some archangels, may suggest a human gender, Christian artists were careful not to given them specific gender attributes, at least until the 19th century, when some acquire breasts for example.

In an address during a General Audience of 6 August 1986, entitled "Angels participate in the history of salvation", Pope John Paul II explained that "[T]he angels have no 'body' (even if, in particular circumstances, they reveal themselves under visible forms because of their mission for the good of people)." Christian art perhaps reflects the descriptions in Revelation 4:6–8 of the Four Living Creatures and the descriptions in the Hebrew Bible of cherubim and seraphim (the chayot in Ezekiel's Merkabah vision and the Seraphim of Isaiah). However, while cherubim and seraphim have wings in the Bible, no angel is mentioned as having wings. The earliest known Christian image of an angel—in the Cubicolo dell'Annunziazione in the Catacomb of Priscilla (mid-3rd century)—is without wings. In that same period, representations of angels on sarcophagi, lamps and reliquaries also show them without wings, as for example the angel in the Sacrifice of Isaac scene in the Sarcophagus of Junius Bassus (although the side view of the Sarcophagus shows winged angelic figures).

The earliest known representation of angels with wings is on the "Prince's Sarcophagus", attributed to the time of Theodosius I (379–395), discovered at Sarigüzel, near Istanbul, in the 1930s. From that period on, Christian art has represented angels mostly with wings, as in the cycle of mosaics in the Basilica of Saint Mary Major (432–440). Four- and six-winged angels, drawn from the higher grades of angels (especially cherubim and seraphim) and often showing only their faces and wings, are derived from Persian art and are usually shown only in heavenly contexts, as opposed to performing tasks on earth. They often appear in the pendentives of church domes or semi-domes. Prior to the Judeo-Christian tradition, in the Greek world the goddess Nike and the gods Eros and Thanatos were also depicted in human-like form with wings.

John Chrysostom explained the significance of angels' wings: "They manifest a nature's sublimity. That is why Gabriel is represented with wings. Not that angels have wings, but that you may know that they leave the heights and the most elevated dwelling to approach human nature. Accordingly, the wings attributed to these powers have no other meaning than to indicate the sublimity of their nature."

Angels are typically depicted in Mormon art as having no wings based on a quote from Joseph Smith ("An angel of God never has wings").

In terms of their clothing, angels, especially the Archangel Michael, were depicted as military-style agents of God and came to be shown wearing Late Antique military uniform. This uniform could be the normal military dress, with a tunic to about the knees, an armour breastplate and pteruges, but was often the specific dress of the bodyguard of the Byzantine Emperor, with a long tunic and the loros, the long gold and jewelled pallium restricted to the Imperial family and their closest guards.

The basic military dress was shown in Western art into the Baroque period and beyond (see Reni picture above), and up to the present day in Eastern Orthodox icons. Other angels came to be conventionally depicted in long robes, and in the later Middle Ages they often wear the vestments of a deacon, a cope over a dalmatic. This costume was used especially for Gabriel in Annunciation scenes—for example the Annunciation in Washington by Jan van Eyck.

Some types of angels are described as possessing more unusual or frightening attributes, such as the fiery bodies of the Seraphim, and the wheel-like structures of the Ophanim.
