I will only make this comment on the whole Diocese of Orange / kneeling thing.
A lot of the commentators have made the assertion that this is the first time the concept of "mortal sin" has been mentioned in this Dioces of Orange in several decades.
Are these commentators experts on the state of catechesis in the Diocese of Orange? Or are they reaching this conclusion because the bishop is pushing something on the "liberal" side of the political ledger.
Kind of like when people say pro-lifers don't care about the living....
