The Last Supper refers to, in Christian theology, the last meal between Jesus and his apostles, which was held just prior to his death. This meal was a Seder or Passover meal, since all participants were Jewish. The time of the supper was that of the feast commemorating the "passing over" of the Angel of Death in Egypt, just prior to the Exodus from Egypt.

In the process of the last supper, Jesus told his disciples, "Do this in remembrance of me." This command was understood by the early Christians as a command to recreate the Last Supper in a remembrance service.

Initially, the remembrance service took the form of agape feasts. Agape is one of the Greek words for love. This service apparently was a full meal, with each participant bringing their own food, with the meal eaten in a common room. Some echoes of this meal remain in fellowship or potluck dinners held at some churches.

This service is known as the Mass or Eucharist in Catholic traditions, and as the Divine Liturgy in Orthodox traditions. The name Eucharist is from the Greek word eucharios which means thanksgiving or thank you. Catholics typically restrict the term 'communion' to the distribution to the commmunicants during the service of the body and blood of Christ.

Within many Protestant traditions, the name Communion is used. This name emphasizes the nature of the service as a "joining in common" between God and humans, due to the sacrifice of Christ Jesus.

A final variation of the name of the service is The Lord's Supper. This name tends to be used by the churches of minimalist traditions, such as those strongly influenced by Zwingli.
