The Eucharist is “the source and summit of the Christian life (CCC 1324). It is the most important of the seven sacraments because, in it and in no other sacrament, we receive the very body and blood, soul and divinity of Jesus Christ. The Eucharist strengthens the Church and the individual.
Jesus summarized the reasons for receiving Communion when he said:
“Truly, truly, I say to you, unless you eat the flesh of the Son of man and drink his blood, you have no life in you; he who eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day. For my flesh is real food, and my blood is real drink. He who eats my flesh and drinks my blood abides in me, and I in him. As the living Father sent me, and I live because of the Father, so he who eats me will live because of me. This is the bread which came down from heaven, not such as the fathers ate and died; he who eats this bread will live forever” (John 6:53–58).
