Until now, I've not seem that +W ever required anyone to fall in line with any of his views or opinions regarding the New Mass, or New Mass miracles. It's perplexing, but I don't automatically have ill-will against him for this, as some here do.
Maybe it has to do with the lack of charity of certain traditionalists, in that they believe that the New Mass is completely evil, as is the conciliar church, and that both are completely devoid of anything Catholic.
I don't think anyone really has bad will against Bishop Williamson (except for SSPX, perhaps, and Bishop? Pfeiffer, and to a lesser extent Father Hewko).
I like Bishop Williamson very much.
But I think he's going off the rails here, as others have said; he's even doubling down by holding the rejection of NO "Eucharistic miracles" to be tantamount (loosely speaking I hope) to a sin against the Holy Ghost. Never has the Catholic Church required belief in private miracles and private revelations. I could see some other reasons for Bishop Williamson not wanting to cooperate with Father Hewko, but this?
+Williamson's statement was actually even a bit more broad, stating that the rejection of scientific evidence might constitute such a sin against the Holy Spirit, so it could just be a matter of time before he says that rejecting the "scientific evidence" for a Globe Earth would be a sin also.
And that speaks to "scientific evidence", much of which is very subject to interpretation and often falsification. Bishop Williamson's only window into the scientific evidence is from links on the internet (which we all know are all true). Also, there's the very simple problem that the devil can easily simulate such "miracles".
