Speaking of the incarnation, Freddoso got me thinking again.
It is generally acknowledged by Christians that the Son freely assumed a human nature–a nature hypostatically united to Himself. So it must be that case that He is contingently human. But what of this: Is it likewise true that Christ’s human nature is contingently united to the divine person? Or put differently, is the following proposition true,
(P) There a possible world W and a time t such that (i) Christ’s human nature, N, exists at t in W and (ii) N is not united to a divine person.
I think the question is deceptively complex.
