Aristotle knew more about God through the light is his reason than most souls alive today. He did not have the benefit of Divine Revelation, which we enjoy today. Yet if you read his works, particularly his Meta-Physics, you will see how close he came to knowing and loving God. It is a visual thing, you have to read him. Just at the roads built by the pagan Romans paved the way for Christianity to spread to the entire civilized world, so also the philosophy of the Greeks predisposed the intellectual world for the full flowering of sacred theology, having the divine revelation of Jesus Christ as its foundation. As they say, “philosophy is the hand maid of theology”.
That's what philosophers and Catholics say...God says something entirely different...
Col_2:8 Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ.
Philosophy is man's wisdom, not God's wisdom and is deceitful...
