Luther And Zwingli Comparison

As Reformers, Zwingli and Luther agreed on most of each other's doctrines. Both rejected the authority of the Pope and held to the authority of Scriptura sola; rejected the view of the Catholic Mass as a sacrifice; rejected the doctrine of Transubstantiation; agreed to the principle of justification by faith alone; and agreed liturgy should be in the vernacular. But among all these similarities, at the heart of their disagreement was how to interpret the nature of Christ’s presence in the bread and wine in the Eucharist. On this Zwingli and Luther could not agree on, and became the dividing factor between Lutherans and Zwinglians.
Zwingli accounts in the expression, “This is my body,” that the word “is” must not be understood literally,
Thus, Luther disagrees with Zwingli and says Christ’s body is everywhere, and furthermore, the right hand of God is everywhere. Contrary to Zwingli, Luther did not believe that God and man were two separate beings that could be divided, but were in fact one supernatural being. Luther speaks of three modes of the one body of Christ: 1) physical/circumscribed, the body of Christ when he walked on earth; 2) supernatural/uncircumscribed, the body of Christ when he left the grave, came through closed doors, or became the substance in the bread and wine in the Supper, and 3) the body of Christ that is one with God, the divine and heavenly body. However, Luther said that the words, “This is my body,” is what is meant in that Christ is in heaven, and his body is in the Supper. He asserts that the right hand of God is not a specific place but is everywhere which means God is in all places and in all things. He further develops this claim by explaining, what Luther calls, the “modes of existence.” For Luther, understanding these modes of existence requires faith, and if others cannot disprove this knowledge then they cannot say that it is not true. In the modes of existence Christ is able to occupy varying spaces. He can take human form to occupy a certain space with specific measurements as well as occupy an entire space such as a room which
