You are for a "universal indult"? This incident should put the lie to that. The American bishops, for the most part, are opposed to such an "indult" and would oppose it, regardless of what Rome decided. In fact, there is no need for any indult. The whole concept of an "indult" is a fiction--since the old Mass was never abrogated in the first place. But Rome would rather be dishonest and pretend such an abrogation has taken place than buck modernism by being truthful.
I'm not an expert on Church law by any means but something came to mind last night about this incident. If the Tridentine has never been abrogated, if any priest is allowed to say it by an historical papal decree, if this Pope has encouraged its use (controversy of this point aside), then this priest is only guilty of disobedience to his bishop. He is not guilty of disobedience to the Church or to the Pope. The Bishop is being disobedient himself. I don't understand how this priest can be punished. Can't he appeal this to the Vatican?
BTW, I am one of the few who is going to support what he did. I think it was an act of part desperation, part presenting the truth to the laity. I used to think the average Catholic was more informed than they actually are. I've since discovered most people don't even know what the Tridentine is or if they do, they are still completely passive and uninformed. The reaction of this priest's congregation was quite telling.
