That is mistaken, in regards to the men whom I made mention of, for Calvin (or someone near to that man) was one of the first who wrote of "Real Presence" in capital letters, with Calvin writing of pneumatic or spiritual presence.
So as I said, (being that you not understand them) you have no real standing to criticize those persons who you do not fully enough understand.
They were not all of them Zwingli --- and in Calvin's instance at the least, he did very openly disagree with Zwingli as to this issue.
That is in error as well. The presence is in the body as well as soul and divinity. Calvin did not understand the Real Presence of Christ in the Eucharist, nor, in fact much of anything else.
