If Jesus assumed the form of humanity, we would then have to ask if this form is universal. If the forms pre-exist in the mind of God, which most traditions would affirm, then this form is universal. Advocates that Jesus assumed the form of humanity have to come to the conclusion that he assumed a universal humanity–yet no one affirms this.
This is why I reject the popular Patristic thought that Jesus assumed all that was human in order to “heal” it. Jesus didn’t assume all of humanity. He didn’t assume both Male and Female. He wasn’t a German. He assumed a local, particular Hebrew body in a Hebrew maid. Verbalist ontologies do not have this problem. Estrangement ontologies do.
