"Christianity, the foolishness of the Cross, the irrational faith that Christ rose from the dead in order to raise us from the dead, was saved by the rationalistic Hellenic culture, and this in its turn was saved by Christianity. Without Christianity the Renaissance would have been impossible. Without the Gospel, without St. Paul, the peoples who had traversed the Middle Ages would have understood neither Plato nor Aristotle. A purely rationalist tradition is as impossible as a tradition purely religious."
