use of earlier editions In his motu proprio Summorum Pontificum of 7 July 2007, Pope Benedict XVI stated that the 1962 edition of the Roman Missal was never juridically abrogated and that it may be freely used by any priest of the Latin Church when celebrating Mass "without a congregation". Use of the 1962 edition at Mass with a congregation is allowed, with the permission of the priest in charge of a church, for stable groups attached to this earlier form of the Roman Rite, provided that the priest using it is "qualified to do so and not juridically impeded" (as for instance by suspension). Accordingly, many dioceses schedule regular Masses celebrated using the 1962 edition, which is also used habitually by priests of traditionalist fraternities in full communion with the Holy See such as the Priestly Fraternity of St. Peter, the Institute of Christ the King Sovereign Priest, the Personal Apostolic Administration of Saint John Mary Vianney, the Canons Regular of Saint John Cantius, and the Canons Regular of the Mother of God in Lagrasse, France. Since the main difference between the 1962 Missal and prior editions is the liturgy for Holy Week, the church has permitted Tridentine Mass parishes to adopt earlier editions of the Roman Missal published just prior to the 1962 edition. In July 2021, Pope Francis abrogated portions of Summorum Pontificum with the motu proprio Traditionis Custodes which established the new circumstances for celebration of the 1962 Roman Missal. Groups in dispute with the Holy See, such as the Priestly Fraternity of St. Pius X and the Congregation of Mary Immaculate Queen, have continued to use 1962 or earlier editions at their own discretion. For information on the calendars included in pre-69/70 editions (a small part of the full Missal), see General Roman Calendar of 1960, General Roman Calendar of Pope Pius XII, General Roman Calendar of 1954, and Tridentine Calendar. Official English translations The International Commission on English in the Liturgy (ICEL) prepared an English translation of the 1970 Roman Missal, which was approved by the individual English-speaking episcopal conferences and, after being reviewed by the Holy See, was put into effect, beginning with the United States in 1973. The authority for the episcopal conferences, with the consent of the Holy See, to decide on such translations was granted by the Second Vatican Council. ICEL prepared a greatly altered English translation, and presented it
