Transubstantiation is certainly an interesting topic. If analysis indeed confirmed that the wine literally turned into blood, and the wafer literally turned into flesh, I don't see how any natural phenomenon could resolve that. That certainly would be miraculous.
Yeah, but let us frame that in a reasonable manner.
If wafers and wine were turned into flesh and blood, in every church on earth, at a single time and day, which was published worldwide in local newspapers at least a week in advance...that would be a simple miracle.
Anything else is just hearsay. God knows that. So do we.
P.S. It would take many, many of those to make up for the crap we endure. I'd expect to see a miracle a day, from now on.
Is that too much to ask?
