OK, I said earlier that I bowed-out, but I have to interject something.
No.
The consecration can occur outside of the context of Mass—that’s the answer to the OPs question.
It can happen, but the priest would be committing a serious offense, no matter what the circumstances might be.
This (not that part about it being a serious offense – that’s a given) is exactly where we disagree. What this in effect says is that the Church intends for a consecration to occur in a grocery store aisle, as another poster said earlier:
For a priest to stand in a grocery store and start demanding that God become present in the French-bread loaf is absolutely ridiculous. Jesus Christ “obeys” the word and institution of the priest in some sense at the Liturgy, but to think He is bound to enter some sliced bread in a grocery aisle because a priest said the Anaphora is just magic.
It’s clear to me, at least, that the Church intends no such thing, else the question is reduced to the “magic words syndrome” to which I referred earlier.
As I mentioned in a previous post, we know the Church makes allowances
in extremis, and in that type of situation, the intent of the Church is very clear: even absent the full formal ritual, and assuming the priest’s intent, a valid action does take place, but it is still within the context of Mass (as abbreviated as it may be). My point, though, doesn’t bear on
in extremis situations.
Yes, the priest has the power from ordination, but what I was trying to say all along is that the
intent of the priest and the intent of the Church must be the same in order for there to be a valid consecration. Nothing specifically to do with the ritual being followed or a Mass being “complete” or “full” in itself, but strictly and explicitly the question of
intent.
It brings to mind an episode from 19th century France, where a curé apparently went a little bonkers. He was passing a bakery, went inside, and spoke the words of Institution with hands raised over the bread. The poor baker freaked and once the priest left, he shooed-out his customers and locked the doors. He then went, accompanied by a couple of witnesses, to the bishop and explained what had happened. The bishop promptly compensated the baker for all his wares, and sent some of his staff to remove and consume the bread. The question is, why?
To me it’s very clear that nothing actually happened in that bakery, beyond the poor baker and his customers being panicked. At the same time, it also seems to me that the bishop understood that the priest, albeit a little off-the-deep-end, may have had the proper intention but that the intention was most decidedly not that of the Church. Likewise, it seems to me the bishop understood that, even if the priest’s intent was lacking, the incident could be harmful (i.e, a cause of scandal) to the faithful. In either case, the intent of the Church most definitely was not the same as the intent of the priest.
