I appreciated your post a ways up, Vinnie, but one quibble:
Keep in mind that “traducianist” was how his opponents like Julian described him, not Augustine’s own opinion. Augustine refused to take a side on how a newborn’s soul is made, whether from a part of one parent (traducianism) or freshly made by God (creationism). His view of original sin tries to sidestep that issue.
Here’s one place in one of his last works, Unfinished Work in Answer to Julian, where Julian makes the accusation and Augustine responds:
(JULIAN.) According to our custom, then, I was planning to do just this one thing, namely, to free from the interpretations of the traducianists the parts of the law which were subject to insult, by showing that those passages are correct because they are divine.
(AUGUSTINE.) With insulting lips you call traducianists Cyprian, Ambrose, Gregory, and the rest of their companions who admit original sin. But it is not surprising that new heretics give a new name to the Catholics from whom they departed. Others have also done this when they too departed.
(book 1, chapter 6, Roland Teske translation)
So, I think it’s fair to say Augustine wasn’t thrilled with being described that way.
