Page "Mass of Paul VI" Paragraph 91

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 " 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 ".
