I am not about to get into a discussion of epistemology with you. Suffice it to say that if it comes from Revelation, we believe it.

“Faith is certain. It is more certain than all human knowledge because it is founded on the very word of God who cannot lie. To be sure, revealed truths can seem obscure to human reason and experience, but "the certainty that the divine light gives is greater than that which the light of natural reason gives.”
CCC 157
