8.  Can faith contradict reason inherently?

No.  Faith is certain because it is founded upon Truth.  God is god of all knowledge.  If God is all-knowing and all-good, then having faith in Him cannot logically be contrary to reason — to believe this would violate the principle of non-contradiction, and that would violate reason.

“Though faith is above reason, there can never be any real discrepancy between faith and reason.  Since the same God who reveals mysteries and infuses faith has bestowed the light of reason on the human mind, God cannot deny himself, nor can truth contradict truth.”  (Vatican I, Dei Filius 4)

To the extent that we perceive a breach between faith and reason, it means that we lack understanding.
