At the Last Supper, on the night he was betrayed, our Lord Jesus Christ 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.'

​

At the heart of the Eucharistic celebration are the bread and wine that, by the words of Christ and the invocation of the Holy Spirit, become Christ's Body and Blood. Faithful to the Lord's command the Church continues to do, in his memory and until his glorious return, what he did on the eve of his Passion: "He took bread…" "He took the cup filled with wine…" The signs of bread and wine become, in a way surpassing understanding, the Body and Blood of Christ; they continue also to signify the goodness of creation. Thus in the Offertory we give thanks to the Creator for bread and wine, fruit of the "work of human hands," but above all as "fruit of the earth" and "of the vine" - gifts of the Creator. (See CCC 1323, 1333)

​

The Church obliges the faithful to take part in the Divine Liturgy on Sundays and feast days and, prepared by the sacrament of Reconciliation, to receive the Eucharist at least once a year, if possible during the Easter season. But the Church strongly encourages the faithful to receive the Holy Eucharist on Sundays and feast days, or more often still, even daily.

​

To prepare for worthy reception of this sacrament:

• The faithful should abstain from food and drink for one hour before receiving Communion

• Anyone conscious of a grave sin must first receive the sacrament of Reconciliation

​

Youth and adults who have participated in RCIA complete their initiation with the Holy Eucharist.  Children who have been baptized prepare for their first Eucharist (see below) after their first Reconciliation.
