Posing a pastoral question would be different from rejecting an authentic and authoriative teaching, right?
Hypothetical here. If I say, as a Catholic, and as a Catholic bishop at that, “you know, in my country we don’t grow wheat, it is expensive and needs to be imported. Since the Eucharist is a meal, I’m going to say that in MY country, the eucharist will be confected with rice wafer because that is OUR food. Our needs are not being met, we are being hostage to 2000 year old holdovers from a totally different culture.”. . .um, is that hypothetical bishop posing a pastoral question even? No, he’s saying he totally rejects an authoritative Catholic teaching over the valid matter of the sacrament of the Eucharist, and HE is claiming it needs to be changed in HIS country for HIS people ‘needs’, because otherwise they are victims of unfair disrespect of their own culture.
Posing a pastoral question would be more like the bishop going to speak to the Pope and other bishops as a bishop, bringing up the question to them, and waiting for the answer, which, whether he likes it or not, he accepts.
Now, running offeth at the moutheth and acting as though being bishop of X makes him able to ignore, contravene and defy rules which he (incorrectly) thinks only apply to ‘other people’ or 'other times" which HE intends to change on HIS authority don’t make a bishop (IMO of course) posing ‘pastoral questions’ but rather trying to change teachings to suit himself.
