Homer, Plato, Virgil, and the Cross
“What then shall we say if we would restore the medieval bridge from Homer, Plato and Virgil to Christ, the Bible and the church? Shall we say that Christianity is not the only truth? Certainly not! But let us also not say that Christianity is the only truth. Let us say instead that Christianity is the only complete truth. The distinction here is vital. By saying that Christianity is the only complete truth, we leave open the possibility that other philosophies, religions and cultures have hit on certain aspects of the truth. The Christian need not reject the poetry of Homer, the teachings of Plato, or the myths of the pagans as one hundred percent false, as an amalgamation of darkness and lies (as Luther strongly suggests), but may affirm those moments when Plato and Homer leap past their human limitations and catch a glimpse of the true glory of the triune God.
I reject the all-or-nothing, darkness-or-light dualism that Luther at times embraced. But I also reject the modern relativist position that truth is like a hill and there are many ways around it. Yes, truth is like a hill, but the truth that stands atop that hill is Christ and him crucified. To arrive at the truth of Christ, the people of the world have pursued many, many different routes. Some have only scaled the bottom rim of the hill; others have made it halfway. But many have reached the top and experienced the unspeakable joy that comes only when the truth they have sought all their lives is revealed to them. …
If we are to accept these verses [Romans 2:14-15] in a manner that is in any way literal, we must confess that unregenerate pagans have an inborn capacity for grasping light and truth that was not totally depraved by the Fall. Indeed, though the pagan poets and philosophers of Greece and Rome did not have all the answers (they couldn’t, as they lacked the special revelation found only in Jesus), they knew how to ask the right questions—questions that build within the readers of their works a desire to know the higher truths about themselves and their Creator.”
