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.
7. Who said, “Faith seeks understanding” and what does the phrase mean?
St. Anselm made this statement. Basically, what it means is that if you truly love someone, you always seek to deepen the relationship. So, if you love, you always want to know more. If we are passive or don’t care to learn more about God, then we have to question the depth of our relationship with God. Our faith is a lifelong quest.
6. Is faith a human act? Why?
Faith is a human act in that it requires our participation. Faith is only possible through grace, but we need to consent with our free will. We have to consciously choose to submit to God. Faith is not predetermined, and is not predetermined at any point in our lives.
5. What are Fides qua and Fides quae?
Already answered here.
Fides qua is the personal adherence; the belief that you have; the fact that you cling to Him. Fides quae is the assent to the whole Truth which God has revealed — it is the “stuff” of faith; the content of your faith; “what” you believe. The Creed symbolizes the fides quae.
2. What are the limits of such “proofs”?
The limit to these proofs is that the certainty which we can get is incomplete. We can know that God exists, but we cannot know God. Intimacy with God comes from faith and theophany (God’s self-revelation).
