Now I’m in RCIA, so bare with me. I go to a very traditional parish, and during High Mass all of the responses and songs are in latin. I love this and wouldn’t have it any other way, but I was wondering if this is just a characteristic or requirement of High Mass or does it depend on the parish?
I haven’t been to a Low Mass at this church (I’m relatively new to the parish), so I’m not familiar with whether or not they use latin in Low Mass.
I believe that there is technically no longer a distinction between Low Mass and High Mass in the 1970 Missal which is used in a majority of parishes. But some use the terms anyway to distinguish between the types of Masses they offer. If this is what your parish uses then there is no requirement that Latin be used. Although congratulations for finding such a parish. They are rare.
If by Low Mass and High Mass and “traditional parish” you mean that your parish offers the Tridentine Mass (1962 Missal) then, yes, Latin must be used.
Either way it sounds like you have a great parish.
