Those “apologetic” theologians who insist that reason and faith can be reconciled are sometimes called “natural theologians” or “compatibilists”. They often argue that God’s existence can be proved with reason. “Natural Theology” goes back at least as far as Plato (427–347 BC) and Aristotle (384–322 BC), who both appealed to transcendent entities like “The Good” and “The Unmoved Mover”.
