God gives his grace to us through the means of grace — the Gospel, Baptism, the Lord’s Supper and Absolution. The Lord’s Supper is unique in that it is known by several names. Each emphasizes a different aspect of this great gift to us.
The name the Lord’s Supper reminds us that this sacrament belongs to our Lord Jesus, who instituted it and whose Body and Blood we eat with its bread and wine. The Lord’s Supper is both very simple and yet completely beyond our understanding. We trust the Lord who gives it to us and so call it his supper.
When we call the Lord’s Supper the Sacrament of the Altar, we focus on the sacrifice of Jesus. Following his command, we remember that he offered up the body that we eat and the blood that we drink as a sacrifice for our sins. The blessings this sacrament gives — forgiveness of sins, life and salvation — are ours because of this sacrifice.
We speak of Holy Communion because the Lord unites us with himself and with our brothers and sister in Christ in this meal. (1 Corinthians 10:16-17) The Lord’s Supper brings together bread with his body given for us and wine with his blood shed for us. When we eat it, we are united with him in the same way that Baptism unites us with his death and resurrection. We are also brought together as one body with Christians of all times and places and are united with them.
We call the service of worship in which the Lord’s Supper is offered the Eucharist, which is from the Greek word εὐχαριστήσας which means thanksgiving. It refers to our thankfulness for the gift of this precious sacrament. It is sometimes called the Mass (yes, even by Lutherans!), which comes from that Latin words that conclude the liturgy: “Ite, missa est” (“Go, you are sent”) It reminds us that we are sent by God into the world. Most frequently, however, Lutherans prefer the term Divine Service (from the German word Gottesdienst). This term reminds us that two things happen in worship. God serves us, giving us his gifts of his word and sacraments and we serve God, returning to him our thanks and praise for his mercy.
