"What God reveals is intelligible; we can understand it with our intellect. He doesn’t ask us to throw away our minds in order to become Christians. There are people who think that to become a Christian, one must leave one’s brain somewhere in the parking lot. The only leap that the New Testament calls us to make is not into the darkness but out of the darkness into the light, into that which we can indeed understand. That is not to say that everything the Christian faith speaks of is manifestly clear with respect to rational categories. I can’t understand, for example, how a person can have a divine nature and a human nature at the same time, which is what we believe about Jesus. That’s a mystery—but mysterious is not the same as irrational."
