I understand... The reason I posted what I did is that, historically, when people take up this particular question, they end up resorting to human logic to solve the equation and human logic fails every time resulting in the above mentioned heresies. Not saying you are going there, just mentioning that the line of thought seems to lead people there time after time.
And, here is one reason why that is... We end up in a position were we have to say, "I think..." and then prognosticate about what we really don't know for sure. Yes, there are theophanies in the OT, where Christ appeared (or so the context leads) in bodily form before His incarnation, and yes, there are post ascension appearances (to Paul and John in some form or fashion) where Christ is still corporeal. It is difficult to explain those instances away without doing harm to the text, but it is also difficult to rationalize how a pre-existing adult Messiah could be born as an infant and grow in all ways human -- stature, mind, emotions, etc. -- yet that is exactly what the Scriptures present!
If I had to "think" about this and take a stance, I might be inclined to say that Christ has always had a corporeal glorified body, and that He set that aside to be born as a man in all respects human. He returned to that body when He finished His work. But I cannot back that up with any scholarship, nor can I do more than (perhaps) proof-text the idea, so take it with a grain of salt and add it to the list of things that you want to discover for certain when you meet Him face-to-face. :laugh:
