*The belief that Jesus Christ is actually physically and sacramentally present in the bread and the wine at the Lord’s Table, or Holy Communion. The biblical basis for this view includes a literal understanding of Jesus’ words of instruction, “This is my body. … This is my blood” (Mk 14: 22,24) as well as the supposed allusion to the Eucharist in Jesus’ bread-of-life discourse (Jn 6: 53-58). The real presence is taught by Lutherans and Roman Catholics (with substantial differences).
