There are many pieces of evidence that fall into the "I just don't know" category. Things you could give Mr. Moran the benefit of the doubt about.
However, when you find a SINGLE smoking gun, something that shows deception, con artistry, or catching him in a fraud, all the other issues become just so many distractions or "chaff" flying around the *central point*.
If evidence #17, #19, or #21 is really true (since it's hardly conclusive one way or the other), then why would Ambrose produce evidence #666 (the proven forgery)?
That is how a rational man sorts through this. It's not that difficult.
But some people don't know how to think.
You can have a mountain of potential evidence -- some 10% convincing, some 30% convincing, some not convincing at all. But when you have a SINGLE FRAUD in the pile, that isn't just thrown out as "not convincing" or "let's ignore it" -- it actually serves as NEGATIVE PROOF of what you were seeking to prove (e.g., the Catholicity, valid priesthood, or valid episcopal orders of William "Ambrose" Moran)
In other words, you can't have a valid priest or bishop who owns a single forged docuмent. It just doesn't occur naturally in the wild. When you find evidence of forgery, you have a con artist, plain and simple. One has moral certainty of this. Yes, we might lack metaphysical certainty, but moral certainty is sufficient to make decisions for our souls and the souls in our charge.
There are lots of facts about me that prove (to varying degrees) or fail to prove, that I'm a decent Catholic, a good man, etc. But if a person were to find a single smoking gun that I'm a monster (bodies buried in my yard, satanic paraphernalia, etc.) all the various evidence for my goodness would fall by the wayside, right? What does it matter that I paid all my bills on time, have a good credit score, keep my lawn mowed, have happy children, etc. if there were some glaring evidence that I was a psychopath?
Maybe it's my Seminary training helping me here -
