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.
