I need help explaining to the Liturgical minister in my parish a few things about the Tridentine Mass. She has raised these questions before, and I don’t know how to answer them. I need to know why these things are in the Liturgy and what is the theological significance behind them. Here they are:
Why there are two confiteors? one for the priest and one for the people.
Why there is a third confiteor before communion.
Why the Offeritory is silent.
Why the priest only says “per omnia saecula saeculorum” aloud in the Secret Prayer.
Why the canon is silent, except for “Nobis quoque peccatoribus”?
Why are there so many signs of the cross in the canon.
Why most of the post-canon prayers are silent. And why are there many signs of the crosses in the post canon prayers.
Why there are two sets of three “domine non sum dignus” and why is there a seperate one for the priest and people and why does the priest only say “domine non sum dignus” aloud on his.
I know this is a lot…but your help is greatly appreciated.
