More information is needed here. I am skeptical of scientists who seem to specialize in researching miracles, then sell books and lecture about it.
This guy reminded me of a used car salesman in the video.
They need to publish the details of the experiments and make them available to the public. Is that too much to ask? Or are we supposed to take their word for it. Why wouldn't they publish a paper about this amazing find?
Why hasn't the Church approved of the miracle as worthy of belief? After all, the Cardinal of that diocese is now Pope. What a great miracle to have in your own diocese. Why would you not prioritise a full on investigation and approval process if you are trying to grow people's faith.
They also need to have more objective scientists examine the sample and have the study peer reviewed. Zugibe and Castanon are known religious scientists who may be biased and may have ulterior motives. Zugibe examined and approved of Catalina Rivas who is a fake stigmatist - so I am very cautious about his conclusions on the supposed eucharistic miracle.
Not sure I believe that Zugibe was clueless about the nature of the sample he was examining, since he is known for miracle research and received it from a scientist who is known for miracle research. Castanon should have sent a sample to a more objective scientist or several scientists for the sake of credibility. Plus, the story about the host has two versions - one says it was discovered stuck to a candlestick holder in the back of the church and another version says it was dropped during communion. Which is it? Castanon and Zugibe also have differing stories about the experimental process as well.
Finally, if Our Lord was going to turn a host into his physical cellular flesh then why not find a host consecrated at a Tridentine Mass? Using a host from a New Mass sends a message that the new mass is hunky dory with God. Given how they hand the host out like chewing gum, that would seem to me to be self defeating.
Yeah, yeah, Transubstantiation is real. Here, put your grubby hands out.
So I remain unconvinced.
