Memorialism
Memorialism is the belief held by some Christian denominations that the elements of bread and wine in the Eucharist are purely symbolic representations of the body and blood of Jesus Christ, the feast being established only or primarily as a commemorative ceremony. The term comes from the Gospel of Luke : "Do this in remembrance of me", and the attendant interpretation that the Lord's Supper's chief purpose is to help the participant prayerfully remember Jesus and his sacrifice on the Cross, and symbolically renew commitment.
This viewpoint is commonly held by Anabaptists, the Plymouth Brethren, many Restorationist denominations, some Baptists, Pentecostals, and most Non-denominational churches, as well as those identifying with liberal Christianity.
It is not held by most branches of Christianity, who affirm various doctrines, generally referred to as real presence.
History
Early Christianity
While many Church Fathers imply a real presence of Christ in Holy Communion, Clement of Alexandria and Tertullian used the word "symbol" to define the Eucharist: "the Holy Scripture named wine a mystical symbol of the holy blood ", and interpret John 6:53-56 to be about allegories about faith. However, it is disputed if Clement held a symbolic view of the Eucharist, and some have argued that Tertullian held to a view of spiritual presence in the Eucharist.Medieval
Many of the Waldensians rejected a real presence in the Lord's Supper, seeing it as a symbol. The same view was held by Peter Kániš who held to memorialism, against whom Bishop Nicholas wrote a treatise defending the real presence of Christ in the Eucharist against him.Pico della Mirandola argued that Christ is not literally present in the Eucharist but instead it is symbolic of the blood and body of Christ.
Huldrych Zwingli
The theology of Huldrych Zwingli, a Protestant Reformer of Switzerland, is commonly associated with memorialism. Zwingli, who was a former Roman Catholic priest, affirmed that Christ is truly present to the believer in the sacrament or amid a Christian congregation that remembers with strong intensity the events of the Last Supper through the power of God. However, the sacrament - for Zwingli - is not used instrumentally to communicate with Christ, as John Calvin taught.Zwingli argued that the Eucharist is more about the presence of Christ in the minds of people instead of his presence in the elements. This indicates that, although its liturgies remain an important aspect of being a Christian, its potential benefits are not found in any metaphysical interpretation related to the bread and wine used in the ritual.
In addition, unlike Lutheran theology that upholds a sacramental union, Zwingli maintained that the Scripture and the creeds support the idea that Christ sits at the right hand of God the Father in heaven.
