I want to know the answer to the following question:
In what year were the various versions of the Catholic mass finally synthesized?
All the background I'm provided with is that "In 2007, Pope Benedict XVI clarified that the 1962 Mass of John XXIII and the 1970 Mass of Paul VI are two forms of the same Roman Rite, the first, which had never been "juridically abrogated", now being an "extraordinary form of the Roman Rite", while the other "obviously is and continues to be the normal Form – the Forma ordinaria – of the Eucharistic Liturgy".". Is that enough to answer the question?
Answer: yes
