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

Jesus Christ in the eucharist--body, blood, soul, and divinity--is unique to the Catholic faith; it is, in fact, central to it.  During the Last Supper Christ shows us how to fulfill what He says in the above passage.  The priests of the Catholic Church have repeated it continuously ever since.

The Truth of the eucharist is what brought me fully into the Catholic faith.  The Church, the Body of Christ on earth, will stumble, but it will never be abandoned by the Holy Spirit; people will sin, but we will never be separated from God.  I, too, forgive and am forgiven, endure and am renewed because of the eucharist.Here is art depicting the eucharist:
