O.S. Luke:
I have no disagreement that the Early Church and Fathers believed that the bread and wine become Christ’s body and blood. My problem is that for several centuries, no one “explained” the change - it just happened and no one wanted or demaded an explanation (a common Western trait).
I don’t really think the explanation is the important thing for Catholics. Transubstantiation really isn’t a detailed philosophical explanation–not as dogmatized by Trent. The point is simply that it now
is the Body of Christ and hence Christ can be worshipped as present in the Sacrament without danger of idolatry. If you’re willing to engage in Eucharistic Adoration, then I don’t think RC’s will ask too many questions about your metaphysics. If you aren’t, then something more than philosophical niceties is at stake.
O.S. Luke:
The problem is… I don’t know any faith that “uses” Thomism anymore except the Catholic Church and some Evangelical traditions, and R.C.'s, to my knowledge, only use it in the case of Transubstantiation.
I don’t think that’s true, although that’s where Thomas influenced dogma most heavily. I think the problem with a lot of criticisms of the role of Thomism in Catholicism (William Abraham’s
Canon and Criterion comes to mind) is that people assume that Thomism either functions as a whole philosophical system, or doesn’t function at all. But that’s not the way Catholicism works. It’s quite deliberately eclectic. Thomism is perhaps the single most important philosophical/theological system in the history of the Catholic Church. But Catholic doctrine doesn’t depend on any one system. I don’t see that as a problem.
O.S. Luke:
I don’t think it’s a stretch to say that for Thomas A., the reality of the Sacrament exists only in the ideal world of thought - because that’s where you have to be in order to understand substance and accidents. In my opinion, such thought is almost semi-Calvinist. Strict Calvinists destroyed the Sacrament is many Protestant circles, most notably Zwingli.
Zwingli wasn’t a strict Calvinist–he came before Calvin and wasn’t a Calvinist at all. I agree that Aquinas’s view, while not the same as Calvin’s, isn’t as different from it as people think. But I’m not sure why that’s a problem for you. (Wesley’s view of the sacrament, as far as I can tell, was more or less identical to Calvin’s but less afraid of using sacrificial language.) I don’t think it’s true that the reality of the Sacrament exists only in the ideal world of thought. Rather, Christ’s natural body exists under its proper dimensions in heaven. In the Thomist view, Christ’s body also is present in the Eucharist in a mysterious, spiritual manner, but the real physical body is nonetheless present. Yes, he uses a certain kind of metaphysics to make the point. But the point is one that isn’t (as far as I can tell ) significantly different from that of the Eastern Church. And if you think Calvin was too “low” in his view of the Eucharist, then you really have no reason for objecting to Aquinas either.
O.S. Luke:
The main problem is that Thomism rests on the presupposition that “God exists” is rationally demonstrable.
I don’t think Thomism rests on any one presupposition. That was one of Aquinas’s beliefs. But his various theological and philosophical views don’t stand or fall together. The idea that philosophies have one basic principle from which everything else is developed is a peculiar modern monomania (mostly German).
O.S. Luke:
You can show that a First Cause exists possessed of certain attributes. I’m not sure the evidence is demonstrative, as Aquinas thought it was. But more to the point, Aquinas didn’t think that the God whose existence he could prove was identical in all specifics to the Christian God. So I think the common criticism of him on this point misses the mark. Few theologians have been more aware of the limitations of language in talking about God than Aquinas.
O.S. Luke:
Luther and the Eastern church went more of the way of nominalism:
I can’t see that Eastern theology has any similarities to nominalism, except in their common rejection of rational explanation of God.
It’s all very well to cite the East over against Thomism. But we both know that most Methodist churches don’t teach or practice a doctrine of the Real Presence that the Orthodox would think worth shaking a candlestick at. I say this as someone who can probably no longer remain Episcopalian, and for whom the only current alternative to Catholicism appears to be Methodism. So it’s a serious issue for me. The Methodist invocation of Eastern mystery seems a bit specious to me, when actual practice is so radically different.
In Christ,
