human
Having the nature or attributes of a man.
Are you saying that Jesus was NOT fully man yet also fully God? He surely "shared in our humanity" and He was "found in appearance as a man".
I hope Campion will forgive me for responding here.
The idea here is that Jesus IS fully God and fully man; but He is one Person (one Being, one Essence) and not two; and the kind of Person He is, is a divine Person; thus a divine Being.
He is also fully man: a divine person, a divine being, with a human nature.
I'm using some specialized, precise definitions here, of "person," "being," "essence" and "nature," which sometimes makes people (like me) feel like tearing out their hair, but it ends up being important because otherwise you end up with Jesus = 2 "beings," and that ain't right.
