Eucharist (from the Greek εὐχαριστία, or eucharistia, meaning thanksgiving or giving thanks) is a holy mystery (or sacrament) that is celebrated during the Divine Liturgy within the Orthodox Church where the consecrated bread and wine, through the power of the Holy Spirit becomes the Precious Blood and Body of Jesus Christ, that is consumed by prepared Orthodox Christians. Other names for the Eucharist include: the Holy Gifts, Communion, and the Body and Blood of our Lord Jesus Christ Orthodox Christians believe that the Real Presence of God (not merely a sign) is present after the consecration of the Gifts.
