Have you even read Ignatius or Justin Martyr? They're both very explicit that it's not symbolic. Seriously, this is possibly the single best-attested Christian doctrine in history.
As I said, early on there was an automatic assumption that the act inferred participation in a *real* Christ. Drinking the wine represented participation in a real Christ, in what his *real* blood represented.
The emphasis likely was not on using a proper language to explain how the wine constituted the "blood of Christ." Likely we were just made to focus on the need to participate in Christ's "real presence," which was what the act portrayed and intended to lead us into.
It wasn't just wine--it represented something much more sophisticated, which would've been the object of any discussion of the subject. It wasn't ordinary blood, like wine was an ordinary drink. Rather, it was blood with real redemptive powers.
That was the focus. I should think that Transubstantiation was not the early focus. But I can be corrected. Errors can happen at any time--even early in history.
I've read a smattering of the Church Fathers. I'd have to research to find out precisely what they said. I can imagine they did not import a future controversy into the subject, and simply stated things as Jesus stated them.
It can be assumed something is symbolic while we state that the symbolism reflects a very *real* truth.
The wine is clearly symbolic. The bread is clearly symbolic. You would have to lack a gear in your clock if you think otherwise.
It grieves the Lord, I think, that Christians are so silly that in order to prove Christ is real, and that his word is true, they have to prove that an obvious metaphor is serious and real. We do not have to declare a metaphor is not a metaphor simply to prove we *really* participate in Christ when we express this in the Eucharist! Use of a metaphor does not make a religious act a fake.
Sorry, I'm not buying.
When do you think that happened?
When do I think church denominations become egocentric and feel their doctrine alone is the best path? It happens all the time with every one of them. It's something we always have to watch out for.
In history, the Catholic Church, like all future church denominations, was mixed, true believer with purely nominal believer. The nominal believer views sacraments differently from how the true believer views them. But in time, believers can gradually allow the nominal believers to view things in a purely external way. And the sacrament then becomes a means of grace and not a reminder of grace we've already experienced.
I really don't know how long this process took, to turn religious sacraments into a means of grace. Institutionalization of holy requirements is as old as the Pharisees and Saducees. The laws and sacred acts become a false door into God's house. True believers enter in by faith in Christ, and not by faith in the rituals themselves.
I don't care to denounce the Catholic Church since it was the only Church in the West for a long time. I might as well put down my own denomination, because they are mixed, as well, and have errors. We just need to clean things up for ourselves, even if we can't clean up the whole organization. But that's just how I see it, and I have no personal axe to grind.
