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." ˜Catechism of the Catholic Church
The Holy Eucharist is the greatest gift ever given to man. The second Sacrament of initiation, it is the greatest of all the sacraments since it is truly the living presence of Jesus Christ, Body and Blood, Soul and Divinity, which nourishes the Mystical Body with His very Flesh. That is why this sacrament is called the Blessed Sacrament, it is more than just an outward sign, it is the very Person of Christ and the very pinnacle of our faith.
