>>Then he wouldn’t be fully man.<<

By jove, then I think we are on to something here! If He Got his God nature from being God, then He must have gotten his fully human nature from a fully human ie sinfull nature, mother. That would mean that Mary could not have been without sin or Jesus would not have been able to carry our sin for us!

If Christ got a fully sinful human nature, from his fully sinful mother then how could he be without sin?

Not possible.

As for the Atonement, recall the “Passover Lamb without blemish”? Christ bore our sins because he was perfect, because he was sinless. Else the whole kit’n’kaboodle doesn’t work.

Exactly...Jesus could not have been tempted by sin unless he had the same nature as everyone else on the planet...
