Finishing up a late night with a good book on Catholic apologetics.
Faith and reason are interdependent. One of the great secrets of the universe is that reason leans on faith every but as faith leans on reason. Rightly did St. Augustine say, “I believe that I may understand.” It’s not that people who lack Christian faith cannot know anything. But anyone who knows anything must first put faith in principles that are tacit, unproven, and unprovable. We have good reasons to believe such things. But we don’t have proof. We believe that we may understand.
