O God, who have called us to participate
in this most sacred Supper,
in which your Only Begotten Son,
when about to hand himself over to death,
entrusted to the Church a sacrifice new for all eternity,
the banquet of his love,
grant, we pray,
that we may draw from so great a mystery,
the fullness of charity and of life.
Through our Lord Jesus Christ, your Son,
who lives and reigns with you in the unity of the Holy Ghost,
one God, for ever and ever.
By celebrating the Last Supper with his apostles in the course of the Passover meal, Jesus gave the Jewish Passover its definitive meaning. Jesus' passing over to his father by his death and Resurrection, the new Passover, is anticipated in the Supper and celebrated in the Eucharist, which fulfills the Jewish Passover and anticipates the final Passover of the Church in the glory of the kingdom. (CCC 1340)
I give you a new commandment, says the Lord: love one another as I have loved you.
