Not according to Paul who writes:
"For as often as you eat this bread and drink this cup, you do proclaim the Lord's death until He comes." [I Corinthian 11:26]
According to Paul, even after consecration, it is still bread and that is what you are eating -- despite what the Aristotelians in the church contend.
>> Not according to Paul <<
So do you now believe in consubstantiation, or is this another time-waster? I’m going off on my own here, but:
Was Paul referring to bread as a substance, or as an accident of substance? Bread is formed from baking dough; bread isn’t bread if it isn’t baked. Hence, I would propose that what we mean by bread refers to an accident. Taking this to an extreme, I suppose you could propose that all of energy-matter is of a single substance, since all of energy and matter can be transmuted without being transubstantiated. But even at that apparently ridiculous extreme of the definition, the transubstantiation upholds its definition: even if all of matter is but of one substance, then the Eucharist still is transubstantiated, because what was simply matter is now Spiritual.
