I wonder if I might ask whether you or any of your readers know the rubrics concerning the celebration of Mass (EF of course) at a side altar in a Church where Exposition of the Blessed Sacrament is in progress? For example, is a Missa cantata allowed? Are bells rung? What Masses are actually allowed, Mass of the day or only of peace or votive of the Blessed Sacrament? and so forth. No reference to the Clementine Instruction that I have found so far has been terribly helpful on these points so any help you or your readers can give would be much appreciated.
