Yes and no. “Eucharist” is a Greek word that means “thanksgiving”. At first it was the name for the prayer that preceded the transformation of the bread and the wine into Christ’s Body and Blood in the liturgy of the early Church. Later the term was applied to the whole celebration when the Church gathered for prayer. The Catechism teaches that we chose this word as the title of our liturgy because everything we do when we gather is an act of thanking God for creation, salvation and sanctification.
“Mass” is an English rendering of the Latin term “missa.” In Latin the Mass ends with “Ite missa est,” which translated into English means “Go, it is sent,” the “it” being the Church. From the Latin word “missa” comes the English word “dismiss.” So “Mass” actually means “dismissal.” The celebration takes its name from the sending forth that occurs at the end of every liturgy, because to be sent (in the name of Christ) is the mission of every disciple.
The Mass has 5 parts: the gathering, the liturgy of the Word, the presentation of the offerings (gifts), the Eucharistic (thanksgiving) prayer, and Holy Communion. Each time we participate in Mass and receive the Eucharist worthily, we become what we receive – the Body of Christ. And in so doing, we become the Church.
The Eucharist is also a sacrament – it’s the sacrament. It is the mysterious center of all that the Church is and does, because the historic sacrifice of Jesus on the cross, and the salvation he won for us, is made present to us during the words of consecration. And so the Fathers of Vatican II could write that the Eucharist is the “source and summit of the Christian life”. St. Teresa of Calcutta challenges us to cultivate a deeper relationship with Christ in the sacrament: “Your life must be woven around the Eucharist”, not just for an hour on Sunday, but every day.
