Communion (Eucharist, Lord's Supper)
The sacrament or ordinance of bread and wine commemorating Christ's Last Supper.
Communion is the sacrament (Catholic, Orthodox, Anglican) or ordinance (Baptist, evangelical, most Pentecostal) of bread and wine instituted by Christ at the Last Supper. The Catholic and Orthodox traditions call it the Eucharist (Greek: thanksgiving) and hold it as the central act of Christian worship, with the bread and wine becoming the body and blood of Christ. Most Protestant traditions call it Communion or the Lord's Supper and hold a range of theological positions on what is happening (Lutheran sacramental union, Reformed spiritual presence, evangelical memorial). Specific practice on who may receive (open versus closed communion) varies sharply across Christian traditions.
