The Fifteen Anathemas against Origenist teachings are associated with the 2nd Council of Constantinople (553 AD). Anathema VII caught my eye (http://www.ccel.org/ccel/schaff/npnf214.xii.ix.html):

If anyone shall say that Christ (of whom it is said that he appeared in the form of God and that he was united before all time with God the Word and humbled himself in these last days even to humanity) had (according to their expression) pity upon the divers falls which had appeared in the spirits united in the same unity (of which he himself is part), and that to restore them he passed through divers classes, had different bodies and different names...let him be anathema.

These all addressed Origenist abuses (pre-existence of souls, etc.). But what’s interesting here is the first parenthetical about Christ. The anathematized items get introduced with the bold “had.” What’s in the parenthesis is orthodox summary.

Anyhow, what interests me is that Christ is said to have been “united before all time with God the Word.” Now THAT is interesting, because it’s obviously recognized that the Word “appeared” and “humbled himself in the last days,” i.e., the Word “became” flesh. So how is it that “Christ” (who is the incarnate Logos) is "forever united to God the Word"? See the problem?
