It is possible God could effect an authentic Eucharistic miracle st a NOM to preserve conciliarists faith in the real presence (a dogma directly undermined by that rite, which God could choose to combat by such miracles).
Whether such alleged miracles are authentic is another matter. I merely show such a miracle could bear good fruit, contrary to the gratuitous position of His Excellency’s opponents.
Traditionalists do have a common fault, and Tradition has a weak spot. There is a downside to the "Traditional Movement", and that is: a tendency to a "bunker mentality" where you hunker down with your family, get outta dodge, find yourself a Tridentine Mass somewhere, and let the whole world go to hell.
Sorry, but Our Lord can't do that, and His holy faithful Bishops can't do that. Someone has to care about those HUMAN BEINGS with IMMORTAL SOULS who are CAPABLE OF PRAISING GOD FOR ETERNITY -- even if we Trads are saving our own souls by staying aloof from the Conciliar Mess. That might honestly be the best or only solution for us -- if we didn't, we'd get contaminated.
NEVERTHELESS, it doesn't follow that everyone in the Novus Ordo is evil, lacks the Faith, or the whole thing is 100% invalid. +ABL never held this, so neither do I. I believe +Williamson is just following this line of reasoning and this teaching of the providential, saintly Archbishop.
When +Williamson is admitting the Novus Ordo could be valid in some cases, he's being rational, going against his feelings, and practicing "agere contra" a.k.a. doing THE OPPOSITE of what comes natural to him. I know that's the case for me. Everything about the Novus Ordo turns me off. There's not even 1% nostalgia in it for me, since I never attended it. But I'm not going to exaggerate its evils, not even by 1%.
