Isn the Latin Mass just the regular Mass said in Latin?
The Ordinary Form (the Missal of Pope Paul VI -1969) and the Extraordinary Form (the Missal of Blessed John XXIII – 1962) have similar elements, but each has its own distinguishing characteristics. For example, each form has its own liturgical calendar and cycle of readings. The Ordinary Form has multiple Eucharistic Prayers but the Extraordinary Form uses the Roman Canon exclusively.
