The Eucharist, also called Holy Communion or Lord's Supper and other names, is one of the two most important Christian sacraments. Almost every Christian denomination celebrates in some form this rite or ritual of worship and remembrance, which Christians generally believe Jesus instituted at his last meal with his disciples before being turned over to his executioners. Beginning in the Early Church as a prayer or blessing over bread and wine associated with a common meal that followed the form of earlier Jewish blessings, it has evolved within the theologies of the various denominations into a broad variety of liturgies that range from the silent communion of the Quaker to the transubstantiation of bread and wine into the actual (though not physical) Body and Blood of Christ of the Roman Catholic Church, in spite of which "there is more of a consensus among Christians about the meaning of the Eucharist than would appear from the confessional debates over the sacramental presence, the effects of the Eucharist, and the proper auspices under which it may be celebrated."The phrase "the Eucharist" may refer not only to the rite but also to the "bread" and "cup" used in the rite, and, in this sense, celebrants may speak of "receiving the Eucharist", rather than "celebrating the Eucharist".
