Pope Benedict calls the traditional Latin Mass the Extraordinary Form. He recognizes that the Ordinary Form is the one widely used that was developed after the Second Vatican Council and promulgated in 1969. Actually, the 1962 Missal of Blessed John XXIII was the only Missal issued during the Second Vatican Council.
What have Pope John Paul II and Benedict XVI said about the Tridentine Mass?
In his 1980 letter to the Bishops on the Holy Eucharist, Pope John Paul II said: "There are also those people who, having been educated on the basis of the old liturgy in Latin, experience the lack of this 'one language', which in all the world was an expression of the unity of the Church and which, through its dignified character, elicited a profound sense of the Eucharistic mystery. It is therefore necessary to show, not only understanding, but also full respect towards these sentiments and desires. As far as possible, these sentiments and desires are to be accommodated."
Then in 1988 the same pope wrote: “Respect must everywhere be shown for the feelings of all those who are attached to the Latin liturgical tradition by a wide and generous application of the directives already issued some time ago by the Apostolic See for the use of the Roman Missal according to the typical edition of 1962.”
In July of 2007, Pope Benedict XVI wrote: “It is permissible to celebrate the Sacrifice of the Mass following the typical edition of the Roman Missal promulgated by Bl. John XXIII in 1962 and never abrogated, as an extraordinary form of the Liturgy of the Church.”
In the same document Pope Benedict states that a pastor may provide for the celebration of this “extraordinary form” on Sundays and/or weekdays at the request of the faithful.
