Question: What is the wafer at communion??
Answer:
What is the wafer at communion?
Sacramental bread, sometimes called altar bread, Communion bread, the Lamb or simply the host (Latin: hostia), is the bread used in the Christian ritual of the Eucharist (also referred to as the Lord's Supper or Holy Communion, among other names). Along with sacramental wine, it is one of two "elements" of the Eucharist. The bread may be either leavened or unleavened (appearing as a wafer), depending on tradition.
