"Then he took the bread, said the blessing, broke it, and gave it to them, saying, “This is my body, which will be given for you; do this in memory of me.” And likewise the cup after they had eaten, saying, “This cup is the new covenant in my blood, which will be shed for you.”
-Luke 22:19-20
"The holy Eucharist completes Christian initiation. Those who have been raised to the dignity of the royal priesthood by Baptism and configured more deeply to Christ by Confirmation participate with the whole community in the Lord's own sacrifice by means of the Eucharist. At the Last Supper, on the night he was betrayed, our Savior instituted the Eucharistic sacrifice of his Body and Blood. This he did in order to perpetuate the sacrifice of the cross throughout the ages until he should come again, and so to entrust to his beloved Spouse, the Church, a memorial of his death and resurrection: a sacrament of love, a sign of unity, a bond of charity, a Paschal banquet 'in which Christ is consumed, the mind is filled with grace, and a pledge of future glory is given to us."
-CCC 1322-3
"So let us ask ourselves this evening, in adoring Christ who is really present in the Eucharist: do I let myself be transformed by him? Do I let the Lord who gives himself to me, guide me to going out ever more from my little enclosure, in order to give, to share, to love him and others? Brothers and sisters, following, communion, sharing. Let us pray that participation in the Eucharist may always be an incentive: to follow the Lord every day, to be instruments of communion and to share what we are with him and with our neighbor. Our life will then be truly fruitful."
