Primary elements of the Christian service of Holy Communion. This is based on Jesus’ Last Supper with his disciples, in which he blessed bread and wine, saying, “This is my body” and “This is my blood.” Some Christians, especially Catholics and Orthodox, believe that the consecrated bread and wine are literally transformed into the actual body and blood of Christ, although they continue to look and taste like bread and wine (known as the doctrine of transubstantiation). Other groups believe the representation is purely symbolic, while many take a middle course, believing that Jesus is somehow spiritually present in the blessed bread and wine (known as the doctrine of consubstantiation). Never use the word symbol in reference to the bread and wine unless you know that the church you are covering uses that word. In situations involving Catholics, you can refer to the bread as the host, the consecrated wine as the cup, and to either or both elements simply as Communion. See Communion and Eucharist.
