The New Testament uses the language of the Body of Christ so as to drum in a message about unity not simply as cooperation but as a sort of mutual creation: we constitute each other… In the central act of worship, the Eucharist, we come together to be fed—fed buy a reality wholly other to us yet made wholly accessible to us; fed so that we can feed one another. The Eucharist isn't an occasion when we set out to celebrate our togetherness and to encourage each other by the degree of our warm fellowship and close agreement. It is as we meet that we are fed by Christ, and because we are fed by him that we become able to feed each other. Somehow, no account of unity that doesn't bring us to this place is going to be adequate.
