Memorialism is the belief held by many Christian denominations that the elements of bread and wine (or juice) in the Eucharist (more often referred to as The Lord's Supper by memorialists) are symbolic of the body and blood of Jesus, the feast being primarily a memorial meal. The theory comes largely from the work of Reformed theologian Huldrych Zwingli. The term comes from the verse that says "Do this in memory of me" and the attendant interpretation that the Lord's Supper's chief purpose is to help the participant remember Jesus.
