I watched the video.
I didn’t like it because of the jokes, but I can see the point.
I used to know an FBI crime scene investigator as a distant acquaintance, and he said sometimes bodies actually do not decay normally. I thought this was untrue because places like “body farms” actually do studies on the decomposition rates of corpses for forensic purposes. The information is actually used in courts of law for chronological purposes. But even in secular forensic cases, like the death of Pauline Reade, where the victim is found decades later looking like they were alive yesterday, it seems to confound the body farm types of studies. In any case, all this stuff is probably why the Vatican only looks “favorably” upon incorruptibility as miraculous.
It’s worth noting, as the ancient accounts have it, there is usually a lot of other secondary supernatural phenomena accompanying miraculous incorruptibility.
Take the relic of Bernadette Soubirous. The mere picture of her incorrupt body was the beginning of my reversion in later life. But it wasn’t just her relic. Look at the entire story of Lourdes. The miracles that occurred within her order, occur around her relic, and occur at Lourdes itself still today. There’s so much supernatural evidence to draw from - whether a Saint is incorruptible or not seems “favorable”, but it’s probably secondary to whatever graces and blessings are “in effect” within a given area…
