In the first chapter of his letter to the Christians in Rome, St. Paul wrote, “For the wrath of God is revealed from heaven against all ungodliness and wickedness of men who by their wickedness suppress the truth. For what can be known about God is plain to them, because God has shown it to them. Ever since the creation of the world his invisible nature, namely, his eternal power and deity, has been clearly perceived in the things that have been made. So they are without excuse” (Romans 1:18-20).

History bears out the truth of St. Paul’s statement. You don’t need a Bible to know that God exists and that he is eternal, powerful, intelligent, just, and creative. We all live on the same planet, see the same nature, and are able to come to the same obvious conclusions—even if some people refuse.

Nonetheless, Christianity is not a nature religion. It is a revealed religion. God has spoken through the words of the inspired writers of Scripture and through the Church.

So where are the boundaries between what any human can understand about God through reason and what requires revelation?

Prof. Kyle Washut has been discussing just that with our Wyoming Catholic College sophomores as they read St. Thomas Aquinas’ Compendium Theologiae together.
