All the great mysteries of the Christian faith (Trinity, Incarnation-Redemption, resurrection of the flesh--which is the mystery of the Church, incorporation of the world into a living body that rises at the consummation of history) are summed up and linked together in the Gospel words we heard for the Feast of Corpus Christi yesterday. The key to it all--the Eucharist mediates the Trinitarian life to humanity:

"Jesus said to the Jewish crowds: 'I am the living bread that came down from heaven; whoever eats this bread will live forever; and the bread that I will give is My flesh for the life of the world.'

"The Jews quarreled among themselves, saying, 'How can this man give us his flesh to eat?' Jesus said to them, 'Amen, amen, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you do not have life within you. Whoever eats My flesh and drinks My blood has eternal life, and I will raise him on the last day. For My flesh is true food, and My blood is true drink. Whoever eats My flesh and drinks My blood remains in Me and I in him. Just as the living Father sent Me and I have life because of the Father, so also the one who feeds on Me will have life because of Me. This is the bread that came down from heaven. Unlike your ancestors who ate and still died, whoever eats this bread will live forever.'" (John 6:51-58)

Trinity: "Just as the living Father sent Me and I have life because of the Father..."

Ecclesial incorporation into the Trinitarian life through the Eucharist: "...so also the one who feeds on Me will have life because of Me."

Incarnation for the sake of Redemption through the Eucharistic sacrifice of the Cross, by which Jesus becomes available to each human being, initiating the resurrected life of an integrated humanity: "I am the living bread that came down from heaven; whoever eats this bread will live forever; and the bread that I will give is My flesh for the life of the world."
