The Eucharist is "the source and summit of the Christian life."
“Since Christ Himself has said, ‘This is My Body,’ who shall dare to doubt that it is His Body?”
And he took bread, and when he had given thanks he broke it and gave it to them, saying, “This is my body which is given for you. Do this in remembrance of me.”
“What you see is the bread and the chalice; that is what your own eyes report to you. But what your faith obliges you to accept is that the bread is the body of Christ, and the chalice is the blood of Christ. This has been said very briefly, which may perhaps be sufficient for faith; yet faith does not desire instruction.”
The Eucharist is the source and summit of the Christian life. The term “Eucharist” originates from the Greek word eucharistia, meaning thanksgiving.
In the celebration of the Eucharist, bread and wine become the Body and Blood of Jesus Christ through the power of the Holy Spirit and the instrumentality of the priest. The whole Christ is truly present — body, blood, soul, and divinity — under the appearances of bread and wine, the glorified Christ who rose from the dead. This is what the Church means when she speaks of the “Real Presence” of Christ in the Eucharist. (Excerpt from USCCB website)
The transformed bread and wine are truly the Body and Blood of Christ and are not merely symbols. When Christ said “This is my body” and “This is my blood,” the bread and wine are transubstantiated. Though the bread and wine appear the same to our human faculties, they are actually the real body and blood of Jesus. (Excerpt from USCCB website)
The Lord Jesus, on the night before he suffered on the cross, shared one last meal with his disciples. During this meal our Savior instituted the sacrament of his Body and Blood. He did this in order to perpetuate the sacrifice of the Cross throughout the ages and to entrust to the Church a memorial of his death and resurrection. The Institution of the Eucharist is written down in the four Gospels below (Excerpt from USCCB website):
Jesus gives himself to us in the Eucharist as spiritual nourishment because he loves us. By eating the Body and drinking the Blood of Christ in the Eucharist, we become united to the person of Christ through his humanity. “Whoever eats my flesh and drinks my blood remains in me and I in him” (Jn 6:56). In being united to the humanity of Christ, we are at the same time united to his divinity. Our mortal and corruptible natures are transformed by being joined to the source of life. (Excerpt from USCCB website)
The Liturgy of the Eucharist begins with the preparation of the gifts and the altar. As the ministers prepare the altar, representatives of the people bring forward the bread and wine that will become the Body and Blood of Christ. The celebrant blesses and praises God for these gifts and places them on the altar, the place of the Eucharistic sacrifice. In addition to the bread and wine, monetary gifts for the support of the Church and the care of the poor may be brought forward. The Prayer over the Offerings concludes this preparation and disposes all for the Eucharistic Prayer.
(Excerpt from USCCB website)
The Eucharistic Prayer is the heart of the Liturgy of the Eucharist. In this prayer, the celebrant acts in the person of Christ as head of his body, the Church. He gathers not only the bread and the wine, but the substance of our lives and joins them to Christ’s perfect sacrifice, offering them to the Father.
The introductory dialogue establishes that this prayer is the prayer of the baptized and ordained, is offered in the presence of God, and has thanksgiving as its central focus. Following this dialogue, the celebrant begins the Preface, which consists of four different Eucharistic Prayers. After these prayers, communion is then given.
The following timeline follows the traditional Liturgy of the Eucharist:
- Presentation of the Gifts and Preparation of the Altar
- Prayer over the Offering
- Eucharistic Prayer
- Preface
- Holy, Holy, Holy
- First half of prayer, including Consecration
- Mystery of Faith
- Second half of prayer, ending with Doxology
- The Lord’s Prayer
- Sign of Peace
- Lamb of God
- Communion
- Prayer after Communion
(Excerpt from USCCB website)
“Jesus awaits us in this sacrament of love.”
The presence of Christ in the Eucharist is real, true, and substantial.
“It is called: Eucharist, because it is an action of thanksgiving to God.”
Eucharist “makes present the one sacrifice of Christ the Savior.”
