How can you remain a believer in dogmatic holy books given these conditions? What counter-arguments counter?

You are making an assumption. You assume that divine intervention cannot surpass the limitations of the physical without divine intervention. That is, even if the regress argument is true, its only true as a human construct, reasoned by men. And even at that, the argument itself may be wrong. But you place it and its power and its unwavering certain validity higher than God himself. THAT is nonsense. IF god exists then of course he can communicate absolute knowledge. The Bible isnt a technical manual or a scientific text book, its absolute moral knowledge. Your argument here is fundamentally flawed on a host of levels. Faith, by definition, is devoid of certain knowledge... that is what makes it faith as opposed to knowledge... and in accordance to many religions, faith is preferred. Faith is not fallacious, nor are any of the religious zealots who admit to having faith. After all, if absolute knowledge truly is impossible from an atheistic perspective, then even the atheist must have faith in what he thinks he knows.
