Even that Ultimate Truth trick that theists do is merely a line in the sand. It means that beyond that they will not argue. The believer says “X”. The non-believer says “Y”. The believer says, “No, it’s X because God says it’s X!” And for the believer, that’s the end of the argument. If they hold firm to the starting notion that there IS a God and that whatever holy text they reference is correct, they have basically let you know “Beyond this I will not reason with you. Logic means nothing to me.”
Some perhaps, but then you haven’t met Mr. Acquinas.

There are religious folks who haven’t examined their beliefs either. Or at least don’t care much for epistemology.
Logic is a great tool, but it is limited to a subset of reality. We know, or act as though we know, a great deal (some would say the most important things) that cannot be known using reason/logic alone.
We say these thing transcend logic. Not contradict it, not irrational, but go beyond what the tool of logic can be used to know.
