From a reader:
I have often wondered if there was any specially approved liturgy for profoundly/ severely deaf people prior to the liturgical reforms of the ’60s? Surely, there must have been some adaptations of the Tridentine Mass to accomadate their needs? For instance, a Tridentine facing the people, or even it being said in sign langauge or something?
I have absolutely no idea. We will need the help of others on this.
My first impulse is to say that there were no special provisions.
