Institute of Christ the King Sovereign Priest

The Institute of Christ the King Sovereign Priest, Institutum Christi Regis Summi Sacerdotis, abbreviated as ICRSS and ICKSP, is a society of apostolic life of pontifical right in communion with the Holy See of the Catholic Church. The institute has the stated goal of honouring God and the sanctification of priests in the service of the Catholic Church and souls. An integral part of the institute's charism is the use of the traditional liturgy, namely the Tridentine Missal for Mass, the Breviary of John XXIII for the Divine Office, and the Rituale Romanum for other sacraments. The society has undertaken the restoration of a number of historic church buildings.

The institute's rule of life is based generally on that of the secular canons. Its stated mission is the defense and propagation of the reign of Christ the King in all areas of human life, both private and social.

Early years
The institute was canonically erected on 1 September 1990 by Gilles Wach and Philippe Mora in Gabon, Africa, where the Institute still has missions, notably in the capital Libreville. Its canonical status was of diocesan right until 7 October 2008. On that date, it was granted the status of pontifical right by decree, titled Saeculorum Rex, of the Pontifical Commission Ecclesia Dei, on the occasion of the visit of Camille Perl, the vice-president of the commission. Deacons and priests are incardinated into the institute, whose prior general has the right to call to orders. The institute is based in Gricigliano, Italy, in the Archdiocese of Florence. Its international seminary of Saint Philip Neri is also located there, and the institute's ordinations and other major masses are held at the church of San Gaetano in Florence.

Wach serves as prior general and Mora as rector of the seminary. Both received their priestly formation under Cardinal Giuseppe Siri of Genoa.

As of 2022, the institute has 139 priests, as well as clerical oblates who go through formation but may only be ordained up to the permanent diaconate, working instead for the several apostolates of the institute.

The charism of the institute is based on the example of its three patron saints:
 * Francis de Sales, who emphasized teaching the Catholic faith with patience and charity, encouraging all Catholics to a life of holiness through the ordinary means of the Church, such as devout attendance at Mass and frequent confession.
 * Benedict of Nursia, with his love for the solemn celebration of the liturgy, his emphasis on work and prayer, "Benedictine hospitality", and role in laying the groundwork for an integral Christian civilization in medieval Europe.
 * Thomas Aquinas, with his emphasis on the harmony between faith and reason.

The institute also honors as its primary patroness the Virgin Mary under the title "of the Immaculate Conception, to Whom it is consecrated." Saint Thérèse of the Child Jesus is the patroness of its African missions.

Apostolates
In the United States, the institute is headquartered in Chicago, with presences in Illinois, Wisconsin, Missouri, New Jersey, Connecticut, California, Arizona, Michigan, Pennsylvania, Louisiana, and Ohio, with a forthcoming apostolate in Worcester, Massachusetts announced in September 2023. In Chicago, the institute is restoring the historic Saint Clara/Saint Gelasius Church on Carmelite Way, which is also the site of the headquarters for the American Province of the institute. Upon completion, it will become the Shrine of Christ the King.

Its oldest United States apostolate is the Saint Mary Oratory in Rockford, Illinois, and its newest is the St. Elizabeth of Hungary Shrine in Cleveland, Ohio. In Kansas City, Missouri, Bishop Robert Finn established an oratory (a public church where Mass and other rites may be celebrated) in 2005 for the institute at a historic church otherwise in danger of being closed. Also in 2005 St. Francis de Sales Church in Saint Louis, Missouri was established as an oratory under care of the institute, to serve the city and region. It is leading efforts to restore the church and has installed a new organ. The superior for the United States is Canon Matthew Talarico.



In England, the Institute is active in the Diocese of Shrewsbury, where they have apostolates in New Brighton and Shrewsbury, in the Diocese of Lancaster, where they have two churches in Preston and the Diocese of Plymouth, where they have a church in Torquay. In 2011 the Bishop of Shrewsbury invited the institute to re-open the Church of Saints Peter, Paul, and Philomena in New Brighton.

Since Saint Patrick's Day, 17 March 2006, the institute has had a presence in the Diocese of Limerick in the Republic of Ireland. In Limerick City, they purchased Sacred Heart Church, Since May 2010, the institute has expanded into the Irish diocese of Galway, where weekly Mass is offered at Saint Mary's College school; monthly Masses are offered by priests of the institute in Ennis. The institute is also closely involved in the annual Catholic Voice conference held in Limerick, which features amongst its regular speakers Cardinal Raymond Leo Burke and John Hunwicke. Since December 2019 the institute has had an established apostolate in Belfast (Diocese of Down and Connor) following the purchase of the former Fortwilliam & Macrory Presbyterian Church. In April 2021, the Institute purchased a convent in Ardee, County Louth for use by a community of its female religious, the Sisters Adorers.

In addition to its oratories in the United States and missions in Africa, the institute also has apostolates in France, Spain, Belgium, Italy, Germany, Austria, and Switzerland. It also has care of Santi Celso e Giuliano, a papal chapel and minor basilica in Rome, as of 2019. The institute is especially active in the domain of education, running schools in France (Montpellier, Lille and Versailles), Belgium (Brussels International Catholic School), and Africa.

The community celebrates Mass and the Divine Office using the traditional form of the Roman Rite, celebrated according to the pre–Vatican II rubrics. Needlework and embroidery projects form an important part of their daily Ora et Labora ("Pray and Work").
