The Eucharist, also known as Communion or the Lord’s Supper, is a sacrament commanded by Christ for the remembrance of his life, death and resurrection until his coming again in glory. The word Eucharist comes from the Greek εὐχαριστία/eucharistia, which means Thanksgiving. The Eucharist is, to the Church, the central act of Christian worship. Within most Anglican Parish Churches in the Western world it is celebrated at most every day, and at least once a month, but typically once a week.
The evening before he was Crucified Jesus had a meal with his closest disciples; the Last Supper. During the meal he took Bread and shared it with the disciples saying it was his Body, and then took Wine and shared it with them saying it was his Blood of the New Covenant.
As a sacrament it consists of both an outward and visible sign, and an inward and spiritual grace. In the Eucharist the outward and visible sign is the Bread and Wine which is given and received according to Christ’s own command to us. The inward and spiritual grace given is the Body and Blood of Christ which is received by faith.
