For the central truth, or mystery, of the Christian faith is primarily not a matter of words, and therefore ultimately of ideas or concepts, but a matter of fact, or reality.
The heart of the Christian mystery is the fact of God made man, God with us, in Christ; words, even his words, are secondary to the reality of what he accomplished. To be a Christian is not simply to believe something, to learn something, but to be something, to experience something.
The role of the Church, then, is not simply as the contingent vehicle—in history—of the Christian message, but as the community, through belonging to which we come into touch with the Christian mystery.
