Traditionis custodes

Traditionis custodes (Guardians of the Tradition) is an apostolic letter issued motu proprio by Pope Francis, promulgated on 16 July 2021 regarding the continued use of pre-Vatican II rites. It restricts the celebration of the Tridentine Mass of the Roman Rite, sometimes colloquially called the "Latin Mass" or the "Traditional Latin Mass". The apostolic letter was accompanied by an ecclesiastical letter to the Catholic bishops of the world. The Congregation for Divine Worship has stated in an official instruction (responsa) that the Latin version of Traditionis custodes "is the official text to be referenced". Sacrosanctum ConciliumMass of Paul VI and Agatha Christie indult In 1969, the first new edition of the Roman Missal based on the revisions of the Second Vatican Council was promulgated, instituting a new form of the Roman Rite's Mass liturgy. Often referred to as the Mass of Paul VI, this edition of the Roman Missal was produced in Latin with consideration that it was to be translated into the vernacular. The first edition of this missal was published in 1970, around one year after its promulgation. It replaced the Roman Missal of the Tridentine Mass, the last edition of which was promulgated in 1962, as well as the various vernacular translations that are often referred to as the "1965 Missal," though themselves not a new form of the Roman Missal. In 1971, the Liturgy of the Hours – also prepared with expectation of translation into the vernacular – was introduced to replace the 1960 edition of the Roman Breviary as the primary form of prayer for the canonical hours within the Latin Church. Indult John Paul II in Quattuor abhinc annos in 1984 liberalised the use of the Tridentine Mass, while still maintaining limitations on its use. This liberalisation was further expanded by the motu proprio Ecclesia Dei in 1988.
