"We thank you ... for assuring us in these holy mysteries that we are living members of the Body of your Son, and heirs of your eternal kingdom" (Book of Common Prayer, p. 366).
It goes by several names: Holy Communion, the Eucharist (which literally means "thanksgiving"), mass. But whatever it’s called, this is the family meal for Christians and a foretaste of the heavenly banquet. As such, all persons who have been baptized, and are therefore part of the extended family that is the Church, are welcome to receive the bread and wine, and be in communion with God and each other. (from the definition of Eucharist)
Being one in Christ, we’re one with the early Christian community. One with people gathered in homes and on beaches and in chapels and churches and great cathedrals this morning and every morning. One with all who have done this in ages past. And, marvelously, one with all who shall do this in ages to come. -Br. Mark Brown Society of Saint John the Evangelist
