Ladislaus, I checked this article and I understand that bishop Williamson is sometimes rash, writing and speaking many controversial themes that often doesn't have connection (at least not directly) to his state of life, as a traditional Catholic bishop.
This doctor who is skeptic and disproves it as a miracles is an atheist, who thinks that the Novus Ordo or Conciliar Mass is Catholic Mass, etc.
He and some other doctor may be right, that it's some kind of bacteria that occurs with passage of time in damp, public spaces. He and a few other atheistic doctors concluded that this probably happened in some other centuries old Eucharistic Miracles because microscope didn't exit.
But I could also say he too is biased like his colleague, who is a Catholic, at least Novus Ordo Catholic.
The hard truth that WE ALL are biased and have reasons to approve and believe or dispute and a priori conclude that is not possible, so it must be satanic fake miracle.
Both of those statements and mindsets could be dangerous for the faith. This is still matter of personal opinion and subjective, and bishop Williamson should know better that is one of the main characteristics of the (neo)modernism. I didn't know that there hasn't been genetical and some other detailed tests done.
He is also wrong on Garabandal and Maria Valtorta, I don't believe every word he says or writes. But he said he went to Poland, talked with doctors and that priest. Why would he give support to Novus Ordo mass by endorsing "Eucharistic Miracles" that allegedly happened in this type of mass or service?
It goes against archbishop Lefevbre and his fight for Tradition in the Catholic Church.
It doesn't make any sense, unless he is brave enough to search for the truth against all odds, no matter where the truth leads him.
We should be cautious of course, but Devil can't fake true miracle from God. Maybe that wasn't human flesh and blood after all.
