Ordinary Form

The Mass of Paul VI is the most commonly used form of the Mass used today within the Catholic Church, first promulgated by Pope Paul VI in the 1969 edition of the Roman Missal after the Second Vatican Council (1962–65). It is considered the Ordinary Form of the Roman Rite mass, as it is intended for use in most contexts. It is the successor to the Tridentine Mass used since 1570.

In its official documents, the Church identifies the forms of the Roman Rite Mass by the editions of the Roman Missal used in celebrating them. Thus, in his motu proprio Summorum Pontificum of 7 July 2007, Pope Benedict XVI referred to this form of the Roman Rite Mass by linking it with "the Roman Missal promulgated by Pope Paul VI in 1970". The names Mass of Paul VI and Pauline Mass are equivalent to this.

In advance of the 1969 decision on the form of the revision of the liturgy, a preliminary draft of two sections of the Roman Missal was published. The section containing the unvarying part of the Mass is called Ordo Missae (Order of Mass) since at least 1634.

In his letter to bishops which accompanied his 2007 motu proprio Summorum Pontificum, Pope Benedict XVI wrote that "the Missal published by Paul VI and then republished in two subsequent editions by John Paul II, obviously is and continues to be the normal Form – the Forma ordinaria – of the Eucharistic Liturgy." Since then, the term Ordinary Form (abbreviated OF) is often used to distinguish this form of the Roman Rite of Mass from the Tridentine Mass, the 1962 edition of which Pope Benedict declared in his motu proprio to be an authorized "Extraordinary Form" (EF).

The current official text of the Mass of Paul VI in Latin is the third typical edition of the revised Roman Missal, published in 2002 (after being promulgated in 2000) and reprinted with corrections and updating in 2008. Translations into the vernacular languages have appeared; the current English translation was promulgated in 2010 and was used progressively from September 2011. Two earlier typical editions of the revised Missal were issued in 1970 (promulgated in 1969) and 1975. The liturgy contained in the 1570–1962 editions of the Roman Missal is frequently referred to as the Tridentine Mass: all these editions placed at the start the text of the bull Quo primum in which Pope Pius V linked the issuance of his edition of the Roman Missal to the Council of Trent. Only in the 1962 edition is this text preceded by a short decree, Novo rubricarum corpore, declaring that edition to be, from then on, the typical edition, to which other printings of the Missal were to conform.
