I received from the Lord what I also handed on to you,
that the Lord Jesus, on the night he was handed over,
took bread, and, after he had given thanks,
broke it and said, "This is my body that is for you.
Do this in remembrance of me."
In the same way also the cup, after supper, saying,
"This cup is the new covenant in my blood.
Do this, as often as you drink it, in remembrance of me."
For as often as you eat this bread and drink the cup,
you proclaim the death of the Lord until he comes.
In the ecclesial service of the ordained minister, it is Christ himself who is present to his Church as Head of his Body, Shepherd of his flock, high priest of the redemptive sacrifice, Teacher of Truth. This is what the Church means by saying that the priest, by virtue of the sacrament of Holy Orders, acts
in persona Christi Capitis:
- It is the same priest, Christ Jesus, whose sacred person his minister truly represents. Now the minister, by reason of the sacerdotal consecration which he has received, is truly made like to the high priest and possesses the authority to act in the power and place of the person of Christ himself (virtute ac persona ipsius Christi).
Christ is the source of all priesthood: the priest of the old law was a figure of Christ, and the priest of the new law acts in the person of Christ.
- -- CCC 1548
- It is Christ himself, the eternal high priest of the New Covenant who, acting through the ministry of the priests, offers the Eucharistic sacrifice. And it is the same Christ, really present under the species of bread and wine, who is the offering of the Eucharistic sacrifice.
- -- CCC 1410
"By a tradition handed down from the apostles which took its origin from the very day of Christ's Resurrection, the Church celebrates the Paschal mystery every seventh day, which day is appropriately called the Lord's Day or Sunday." The day of Christ's Resurrection is both the first day of the week, the memorial of the first day of creation, and the "eighth day," on which Christ after his "rest" on the great sabbath inaugurates the "day that the Lord has made," the "day that knows no evening." The Lord's Supper is its center, for there the whole community of the faithful encounters the risen Lord who invites them to his banquet:
- The Lord's day, the day of Resurrection, the day of Christians, is our day. It is called the Lord's day because on it the Lord rose victorious to the Father. If pagans call it the "day of the sun," we willingly agree, for today the light of the world is raised, today is revealed the sun of justice with healing in his rays.
- -- CCC 1166
