Linus, sometimes the scriptures show a separation like as you pointed out, Christ not knowing the hour of the end. But not always, like in Acts (where I had mentioned), where Paul equates Christ’s blood on the cross with God’s, not just the man part of Jesus. There is still a mystery to it, but there are times when there seem to be some kind of “overlap”. And even if this were not the case, because we are not talking about attributes or origination, but purely physical location (ie, the God-man was in Mary’s womb, passed through her womb and came out her womb) then Mary is Mater Dei, or Theotokos because the entire person of Jesus is in view. This is analogous to saying “Jesus walked down the beach”, we wouldn’t say "only the “man” part walked down the beach because God is omnipresent, we would say Jesus walked down the beach, and if you saw him you would worship him, not just the “God” part but the entire person. The distinction is maintained via acknowledging that Christ at times was limited and at other times was not. This is the part were we have a mystery that the councils did not explain, nor does scripture. But I fail to see how your logic is working to get around this idea.
