I assume that references to Christmas as the celebration of the Incarnation reflect the inadequate knowledge of human biology of some our traditional sources. In this day and age, I think that, as a matter of principle, Christians should emphasize Christ’s Incarnation - the fact that He was fully God and fully man - from the moment of His conception.
I was also thinking, at the time of my original post, of the fact that posts on this forum sometimes indicate some confusion about Christ’s fully human and divine Personhood.

I doubt that. Looking at his language, Luke certainly knew quite well Christ was present at conception.
Excellent comments, by the way. Just a clarification: Christ is one Divine Person (the Word), but with two natures: human and divine. That’s the Incarnation, and I agree that we do well to emphasize this (not that we shouldn’t celebrate Christmas to the full).
God bless!
