We do not consider the difference significant since both Reform camps deny the real presence of the body and blood of Christ in the unity of the person.
In what does the "Real Presence" consist, Speratus? To say that Christ's body and blood are present with the bread and wine is not the same as to say that they are the bread and wine. The phrase in Latin, hoc est corpus meum ("this is my body"), which Luther insisted on does not indicate that the body is present with the bread. The Romanists go still further and say that the bread and wine become the body and blood, but even that is not to say that they are the body and blood, for Christ never said they the bread and wine become anything, but that they already are.
We know from scripture that the bread and wine remain unchanged and that the body and the blood of Christ are distributed to and received by those who eat and drink. In the communication of the divine attributes, the body and blood of Christ are present in, with, and under the bread and wine in the incomprehensible spiritual mode in which He neither occupies nor vacates space.
Quote
Formula of Concord quoting Luther, the incomprehensible, spiritual mode, according to which He neither occupies nor vacates space, but penetrates all creatures wherever He pleases ; as, to make an imperfect comparison, my sight penetrates and is in air, light, or water, and does not occupy or vacate space; as a sound or tone penetrates and is in air or water or board and wall, and also does not occupy or vacate space; likewise, as light and heat penetrate and are in air, water, glass, crystal, and the like, and also do not vacate or occupy space; and much more of the like . This mode He used when He rose from the closed (and sealed) sepulcher, and passed through the closed door (to His disciples), and in the bread and wine in the Holy Supper, and, as it is believed, when He was born of His mother.
