The Most Holy Eucharist is the source and summit of the Christian life because the Eucharist is the True Body and Blood, soul and Divinity of Our Lord Jesus Christ. The Eucharist - Jesus - is the source from which the Christian life flows; and the Eucharist - Jesus - is the summit, or the highest point of our life and our worship of Almighty God.
The Eucharist is the daily bread that Jesus told us to pray for in the Our Father. The Eucharist is the nourishment that strengthens us to live a life of holiness because the Eucharist is the food that transforms us to become more like Christ. Nothing in the world is more important for us to become who God created us to be than to receive Jesus in the Eucharist.
The Eucharist, the living and real presence of Jesus Christ, completes Christian initiation. Through this sacrament of initiation we participate with the whole community of believers in the Lord’s own sacrifice of the cross.
The Eucharist (from the Greek word "eucharistia" - "thanksgiving") is the Sacrament of the Body and Blood of Christ, who is present under the appearance of bread and wine. In the Eucharist, Christ offers Himself in the Holy Sacrifice of the Mass and gives Himself as spiritual food to the faithful.
At the Last Supper, the Lord instituted the Eucharistic sacrifice of His own Body and Blood. He did this in order to perpetuate the sacrifice of the cross throughout the ages until He should come again, and so to entrust to the Church a Memorial of His death and resurrection.
The Eucharist is the source and summit of the Christian life. As Catholics, we fully participate in the celebration of the Eucharist when we receive Holy Communion. We are encouraged to receive Communion devoutly and frequently. In order to be properly disposed to receive Communion, participants should not be conscious of grave sin and normally should have fasted for one hour.
A person who is conscious of grave sin is not to receive the body and blood of Christ without prior sacramental confession, except for a grave reason where there is no opportunity for confession. In this case, the person is to be mindful of the obligation to make an act of perfect contrition, including the intention of confessing as soon as possible (Code of Canon Law, Canon 916). A frequent reception of the sacrament of reconciliation is encouraged for all.
