I find personally that, despite the radical sensationalist doctrine of some branches of the Church, reason and faith are not opposing forces. God made us in his image, and no matter how flawed that image may now be, our ability to reason is part of that image. Therefore, let man and woman worship the Creator with the mind, the blessed gift from God.
“The things of sense, from whence human reason takes its beginning of knowledge, retain in themselves some trace of imitation of God, inasmuch as they are, and are good; yet so imperfect is this trace that it proves wholly insufficient to declare the substance of God himself. . . Still it is useful for the human mind to exercise itself in reasonings, however feeble, provided there be no presumptuous hope of perfect comprehension or demonstration.”
– Thomas Aquinas, Summa Contra Gentiles 1.8
Despite how “feeble” our attempts are to understand God, do not fear reason, for it is ours from God. Anyone whose heart is filled with the love of Christ will be guided by him. So have faith in God that he will direct your reason toward the Truth, toward Him.
-Until reason leads one to dictate there is no God. In the end, faith has to lead a person; a person’s reason is faulty and can lead to deception.
Reason might also find God to be evil, unwise, and possibly existent only in the beings of mankind (1 Cor 15). I can’t just lay out Aquinas’ argument right here in full, but essentially he says that reason will ultimately approach truth when used properly. It will never reach perfect truth, and we should never assume it will because we cannot ascend to God. Also, we may reach false conclusions when our reason is misused or misguided. The problem is that our sin has affected our ability to reason properly, and now we don’t always see things clearly. But there is one truth which all men will approach in some way. For this reason secular philosophers like Plato and Aristotle found some hint of truth. Plato was close to the nature of God, and Aristotle close to the nature of Joy. God has perfect reason, and we are the image of God. Our reason is in likeness to his, but perverted by sin.
