In order to find the deeper roots of this coincidence between Church and Eucharist we must again go back to the question of the relation between Christology and Pneumatology. All the biblical accounts of Christology seem to speak of Christ as being constituted by the Holy Spirit and in this sense as a corporate personality, the Servant of God or the Son of Man. The Person of Christ is automatically linked with the Holy Spirit, which means with a community. This community is the eschatological company of the Saints who surround Christ in this kingdom. This Church is part of the definition of Christ. The body of Christ is not first the body of the individual Christ and then a community of ‘many’, but simultaneously both together. Thus you cannot have the body of the individual Christ (the One) without having simultaneously the community of the Church (The Many). The Eucharist is the only occasion in history when these two coincide. In the Eucharist the expression ‘body of Christ’ means simultaneously the body of Jesus and the body of the Church.
