From a reader…
Is there a specific rule banning the use of the pre-55 holy week rites, and really the pre-55 missal as a whole? Or may a priest use it if he desires?
Some say, and with good reason, that the pre-1955 rites were richer and reflected a more organic development of liturgy than the edited and revised version imposed by Pius XII. Others say that the imposition of the 1955 rites, which were plugged into the 1962 typical edition of the Missale Romanum, were a trial run for what the Consilium would do to the Roman Rite in the name of the Council.
The legislation that guides the use of the Extraordinary Form says that the 1962 typical edition of the Missale Romanum can be used. 1962, not pre-1955.
I have heard of claims of permissions to use the pre-1955 Holy Week rite, but I don’t believe that any permissions have ever been given by legitimate authority.
I think that, unless the the people who want to use the pre-1955 rites can show documentation that they have permission from legitimate authority, they should just use them and stop claiming that they have permission. Just let it roll! Man up! Be willing to take the consequences if there are any. Pecca fortiter and all that.
