Gedaliah Nadel



Gedaliah Nadel (1923–2004) was an influential rabbi in Israel's Haredi community. He was known for being one of the heads of Kollel Chazon Ish and was the leading authority of Jewish Law in the Chazon Ish neighbourhood of Bnei Brak. He was celebrated as an expert in all facets of Torah and Talmudic knowledge.

Biography
Gedaliah Nadel was born in Šiauliai, Lithuania to Rabbi Reuven Keshel. In 1936, his family immigrated to Mandatory Palestine and settled in the Balfouria Colony in what is now Northern Israel. After briefly studying in a yeshiva in Tel Aviv, he transferred to the Lomza Yeshiva in Petach Tikvah, where he studied under Rabbi Elazar Menachem Shach. As a child, Gedaliah was known for his diligence and devotion to studying Torah, reportedly studying for up to eighteen consecutive hours. Afterwards Gedaliah studied under Rabbi Avrohom Yeshaya Karelitz, known as Chazon Ish, who moulded him into his principal student (recalling his time with the Chazon Ish, Nadel said that the Chazon Ish garnered knowledge in medical science by reading medical journals).

Nadel married the daughter of Rabbi Eliyahu Weiner, a student of the Chofetz Chaim. Following the wedding, they lived in Jerusalem shortly before moving to Bnei Brak, where he lived an ascetic life. When the Chazon Ish decided to establish a special community of religious devotees, he chose Nadel to lead it. As the leader of the community, such leaders as Rabbi Yaakov Yisrael Kanievsky (the Steipler) and his son Rabbi Chaim Kanievsky, turned to Nadel for decisions. Nadel's house was used as a gathering place for the Rabbinic personalities of his day, such as Shach and the Steipler. Nadel also briefly served as the Rosh Yeshiva of the Vishnitz Hasidic yeshiva.

Nadel would learn Maimonides' Guide for the Perplexed immediately after praying Shacharis vatikin.

He died on June 5, 2004.

Opinions
Nadel asserted that certain concepts mentioned in the Torah and Talmud that were not legalistic were not necessarily to be taken literally. His writings were analyzed and taken into account during the Slifkin affair. Jewish British zoologist Rabbi Natan Slifkin's acceptance of evolution and belief "that the world was billions of years old" is reportedly in accordance to views espoused by Nadel. According to Marc Shapiro, Nadel maintained that it is acceptable to believe that the Zohar was not written by Shimon bar Yochai and that it had a late authorship.

Nadel's teachings have continued to exert influence on Haredi leaders.

Works
Many of Nadel's lectures were collected by his various students, and two volumes were published under the title ''Shiurei Reb Gedaliah.'

B'Torato Shel Rav Gedaliah is a compilation of teachings prepared, which, according to the book, is taken from Nadel's audio recordings and published at his request. It was published by Rabbi Yitzchak Sheilat, one of Nadel's main students, and at the personal request of Nadel.

B'Torato Shel Rav Gedaliah was banned by three prominent Bnei Barak rabbis because it supported Darwin's theory of evolution, including sentences such as "Regarding [the idea that] the creation of man in the image of God marked the end of a long process which started with a non-cognizant animal which gradually evolved until this creature was given a human mind... this is an accurate description. Darwin's proofs, and those of geologists, for the existence of early stages of mankind, seem convincing."

In 5772 (or 2010/2011 CE), Sheilat published a new edition.
