 Even though the account has it that these three are different Persons, still, it identifies each with God, which entails their identity with one another; being the same thing as God, they must be the same thing as each other. Given this, it would seem that they can’t differ in any way, e.g. the Son becomes incarnate but the Father does not (7). Mooney replies that the Trinity is mysterious, and that probably a sentence like “The Son became incarnate but the Father didn’t” might be understood as not requiring a simultaneous or eternal difference between the being that is the Son and the one which is the Father. In Markosian’s thought experiment, one would think that person-names would track with the different stages in the career of the one object, so that, say, “Alice” would refer to the thing only in its latest stages, and “Bob” would apply to it only in its pre-mummy career. Thus, names like “Father” and “Son” should refer to God only in one or the other of God’s Person-episodes. Mooney suggests, then, that “The Son became incarnate but the Father didn’t” will be true if and only if the Son but not the Father is the same person as someone who became incarnate, that is, God becomes incarnate in the Person-episode associated with the name “Son” but not in the one associated with “Father” (8).
