The Tridentine Mass, also known as the Traditional Latin Mass or the Traditional Rite, is the liturgy in the Roman Missal of the Catholic Church codified in 1570 and published thereafter with amendments up to 1962. Celebrated almost exclusively in Ecclesiastical Latin, it was the most widely used Eucharistic liturgy in the world from its issuance in 1570 until the introduction of the Mass of Paul VI.

Summorum Pontificum is an apostolic letter of Pope Benedict XVI, issued in July 2007. This letter specifies the circumstances in which priests of the Latin Church could celebrate Mass according to what Benedict XVI called the "Missal promulgated by Blessed John XXIII in 1962" and administer most of the sacraments in the form used before the liturgical reforms that followed the Second Vatican Council.
