In the eucharistic assembly God’s Word reaches man and creation not from outside, as in the Old Testament, but as “flesh” – from inside our own existence, as part of creation. For this reason, the Word of God does not dwell in the human mind as rational knowledge or in the human soul as a mystical inner experience, but as communion within a community. And it is most important to note that in this way of understanding Christ as truth, Christ Himself becomes revealed as truth not in a community, but as a community. So truth is not just something “expressed” or “heard,” a propositional or logical truth; but something which is, i.e. an ontological truth: the community itself becoming the truth.
