 Moreover, theology had reasons of its own to be suspicious of experience and (what passes for) reason. Of central importance in this regard is the idea that one’s rational faculties can be damaged by sin. Although this idea was articulated by a variety of early Christian theologians including Tertullian and Augustine (and has obvious analogues in classical virtue theory), it came to be given special attention within the Protestant tradition. The reformers held that the human intellect had been corrupted by humanity’s fall from grace, and that consequently the truth of Christianity could be apprehended only by faith. Protestant theologians from Luther and Calvin to Karl Barth have thus affirmed the priority of faith not only to “works” but also to natural theology.
