If the faithful were illiterate and uneducated, having no access to these documents or if they were difficult to attain, then and only then would I agree that the burden laid upon the bishops (upon the bishops, because the priests derive from the bishop, and so it is his duty to keep them accountable). However, because we do have access it is our duty to at least have a nominal knowledge, and I think that this thread topic is one of those that we should have some knowledge of. It is the way that we worship G-d (it is not our Mass, but G-d’s Mass. However, I think that we own it in the sense of, as worshippers of G-d, we should feel it important that the way we worship is holy and worthy).
