Transubstantiation vs. Real Presence

Transubstantiation vs. Real Presence (blog.kennypearce.net):





"Here is the metaphysical background: Aristotle was a proponent of what is called a "hylomorphic" metaphysics. That is, he affirmed that material objects were made up of "matter" (Gr. hylas) and "form" (Gr. morphos). There is a lot more complexity than this, but this is the basic idea. This is related to his distinction between "substance" or "essence" (Gr. ousia) and "accident" (I don't know the Greek word for this). The matter of an object is the stuff it's made out of, and it's form is its shape or organization. For the Scholastics, the Latin "species" seems to have been related to Aristotle's "form" but been more closely related to our cognition (the Catholic Encyclopedia article on this didn't make that much sense to me). Objects also have an essence, which is that in virtue of which it is the thing it is, and various accidents, or properties that could change without the object being destroyed. Often, the essence of an object is thought to be a collection of essential properties; thus I might be essentially human."



The last thing I want to cover is the issue of the Platonist leanings of many of the early fathers, notably the Alexandrians and Augustine. I shouldn't have to take pains to show this, because the Catholic Encyclopedia says, "even Augustine was deprived of a clear conception of Transubstantiation, so long as he was held in the bonds of Platonism." Nevertheless, I will at least try to explain it.
Platonism holds that material objects are what they are in virtue of their "participation" (more literally: "having a share") in a transcendant, changeless, immaterial "form" (not morphos, but eidos or idea, which Aristotle also uses, but in a somewhat different meaning than morphos, I think). You and I are both human because we participate in the form of Human, or, as Plato often says Humanity Itself. The bread is bread because of its relationship to Bread Itself. Things are, of course, generally participants in multiple forms, and everything is a participant in Goodness Itself to a greater or lesser degree because Plato holds to a privation theory of evil (which is where Augustine got it), so anything that had no goodness at all would not exist. Christian Platonists generally want to avoid the idea that the forms are co-eternal with and independent of God, so they say that they exist in God's understanding.
A Platonist does not have a concept of an essence as an Aristotelian does. Furthermore, Plato himself, and I believe most Platonists following him, generally cashes out "participation" in terms of "being patterned after." It is very difficult to see how the bread could change from being patterned after bread to being patterned after the body of Christ without any perceptible change. In what would the patterning consist? How does this object resemble a human body, and how Christ's body in particular? Now, there must be some way of getting this to work, because Father Nicolas Malebranche was a very intelligent Platonist Catholic priest in the 17th/18th century, after the Council of Trent, and he must have come up with something, but I don't know what he said.
At any rate, it is highly unlikely that any Christian Platonist held to anything like transubstantiation prior to Malebranche, and a great many of the early fathers, including, as I have said, the Alexandrian school and Augustine, were Platonists.
The situation is even worse for idealists such as myself (or 18th century Anglican Bishop George Berkeley). We don't believe that there is any such thing as the essence or substance or matter of the bread. All that exists, according to idealism, is what the Scholastics would call the "species." Transubstantiation is thus puzzling for the Aristotelian, more puzzling for the Platonist, and completely incoherent for the idealist. I should also note that most contemporary philosophers don't believe in any of these three theories, but transubstantiation is probably also incoherent for them, since material objects don't have undetectible essences (though they may have essential properties).
Now, a Christian idealist does have to come up with some explanation for the bodily resurrection and be able to say that the body that is raised is in some sense the same body although it is radically transformed in terms of its phenomenal properties. Whatever solution one comes up with for this problem could probably also be used to make sense of the doctrine of the Real Presence. However, this view cannot possibly look anything like transubstantiation, for the reasons discussed above.
