From a reader:
I recently inherited a 1942 Benziger Bros altar Missal. The canon was modified to include St. Joseph by a past priest. Can this missal be licitly used by a priest, providing he was following the rubrics and calender of the 1962 Missal?
Sure. If you don’t have a 1962 edition, then that old Missal can do – mutatis mutandis – in a pinch. However, depending on the feast, you might have to double check your texts.
That said, make sure your priest and or your parish has a true 1962 Missale Romanum. There are nice reprints which I reviewed here.
Every sacristy should have one or it is not adequately provisioned.
