The Eucharist, also known as Holy Communion or the Lord's Supper, is a sacrament that was instituted by Jesus Christ at the Last Supper. It consists of bread and wine that are consecrated by a priest and become the body and blood of Christ. The Eucharist reenacts the sacrifice of Jesus on the cross and is a remembrance of his commandment to "do this in memory of me." It is the source and summit of the Christian faith.
