Peary,
I have never questioned or doubted that the ECFs unanimously believed and taught the Real Presence.
They did not, however, teach Transubstantiation.
This is not because they didn’t use the word, it’s because they were completely unaware of the idea.
The repeated assumption by Catholics here that they did and that there is a one-to-one correspondence between what they believed and what you believe today is cartoonish.
**There is alot to be said about the ECF’s on the Real presence. What Steadfast has commented here does not in any way disqualify transubstantiation from the ECF’s. Because there was no dispute of the real presence to reveal transubstantiation. Why put a fight where there is none about the real presence. These all believed, with no doubt, did not question the true presence, and like you stated were unanimously were in agreement. Not to mention they taught the true presence.
You are applying late century attacks on the Eucharist to the early church fathers where Christendom never questioned the true presence it was believed as Catholics still believe today.
Trying to find arguments against transubstantiation from the early church fathers is not a reasonable argument, because the early church fathers already accepted the true presence. They did not argue the true presence, only taught it and lived it.
As far as I can see from the ECF’s their belief in the true presence does not disqualify transubstantiation, even though they did not have cause to clarify the true presence it was already believed.
So you have a difference in opinion. The bottom line the ECF’s have a valid Eucharist, and a valid priesthood to properly confect the bread and wine, into the body and blood of Jesus. How this can happen, they believe it to be true and mystical.
When the True presence came under attack, Rome and her Majesterium, gave a definition of transubstantiation to the world intellectuals (science) so that they can understand and come to believe.
Again Transubstantiation does not exhaust the meaning of the Eucharist, it explains what happens to the bread and wine, To the (flesh) human senses. This definition does not conflict with any of the early church fathers, as long as the Spirit aspect of the Eucharist is mentioined which states the bread and wine, consecrated validly becomes the body, blood, soul and divinity. There are two aspects of understanding transubstantiation, one is by the Flesh, bread and wine remain these to our senses. The other is the Spirit, which bread and wine become the body,blood,soul and divinity of Jesus Christ. Which do you believe, Roman Catholics believe both. So which are you flesh, or Spirit. If you are Spirit then you accept the 2000 year old Catholic view, if you are flesh then you are on your own.**
