In response to a recent blog entry, a reader writes:
let's say I'm Latin rite, and so I must go to Mass on the Feast of the Assumption. Can I go to an Eastern rite liturgy instead, even if they don't celebrate the Assumption on that day? It's not just different readings, ceremonies etc., but it's a daily mass instead of a Solemn mass.As noted before, here is what the law says:
A person who assists at a Mass celebrated anywhere in a Catholic rite either on the feast day itself or in the evening of the preceding day satisfies the obligation of participating in the Mass [CIC Can. 1248 §1].Note that there is nothing in this about the rite you are attending having to be celebrating the same feast or offering a "solemn Mass" or anything like that. The fact is that by going on such a day you are celebrating the feast and fulfilling your obligation regardless of what is going on around you. By attending "a Mass celebrated anywhere in a Catholic rite" you are "satisf[ing] the obligation of participating in the Mass." Period.
