What proof is there for faith?

[Quaremerepulisti]

- Bayes' Theorem shows that once 100% certainty is reached no later evidence at all can result in a reduction of that certainty. 

It does?  Bayes' theorem is either undefined (dividing by 0), or trivially true (P(A) = P(A)), at the extremes of 0 or 1 probability.  IOW's Bayes' thm is only useful in the mushy middle.

I'm talking about prior probability.  If the prior probability is 100% the posterior probability will likewise be 100% no matter what the likelihood of the new evidence given the model.  (Unless the likelihood is exactly zero, in which case the posterior probability is undefined.)

Well, of course, but I am saying that the mystical faculty allows one to see the integral holiness of the Catholic religion, not just that parts of it are good as in Islam.

Can you shed some light, dear Quare, as to how you think your particular mystical experiences permitted you to see the integral holiness of the Catholic religion?  Perhaps that might help...

How can the Catholic Church be from God and yet the religion not be true?  True, you don't know this truth in the same way you know the answer to a differential equation.

Because God can, and does, plant partial truths, and some select goods, in all religions.  These are all necessarily from God.  Please note that I did not make the claim that the Catholic Church was integrally from God in my post above.  This is precisely what I want to settle vis a vis the act of faith.

Sure.  That is trivially true...you did not need Bayes' thm for something so obvious.  If you are a priori certain about something, no evidence can change that, otherwise you were not certain to begin with.

No, I can't, unfortunately.  I can't lay out the manner in which mystical sight works the same way I can draw a lens, retina, optic nerve, etc.

But just as you can see that certain parts of the Quran are good, I can see Catholicism in its totality is good.

Ah, OK.  But you were able to identify some evil in the Quran and in Islam along with the good.  Is there any evil you can identify in Catholicism?

I think this is an apples and oranges fallacy, since I am not claiming that I know that certain parts of the Quran are good from a mystical experience.  Ironically, it logically follows that the Quran possesses some truth if one knows a priori that Catholicism is true, since the Quran teaches a subset of the (integrally correct from your view) Catholicism (homosexuality one obvious example).

No, I cannot, at least not definitively.  I suppose this is a sign that I have supernatural faith, but does not prove it to be so.
