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.
