 “The Father”, then, is a disguised description, something like “the God who is in some life unbegotten” (2012b, 335) (For “the Son” we would substitute “begotten” for the last word.) Because the “=” sign can have a temporally non-rigid description on one or both sides of it, then there can be “temporary identities”, that is, identity statements which are true only at some times but not others. Leftow gives as an example the sentence “that infant = Lincoln”; this is true when Lincoln is an infant but false when he has grown up. Such identity statements can only be true or false relative to times, or to something time-like (2004, 324). If the terms “Father” and “Son” are temporally rigid, or at least like such a term in that each applies to God at all portions of his life (which isn’t temporally ordered), then 4 does follow from 1–3. But 4, Leftow argues, is theologically innocuous, as it means something like “the God who is in some life the Father is also the God who is in some life the Son” (2012b, 335). This is “compatible with the lives, and so the Persons, remaining distinct,” seemingly, distinct instances of God (each of which is identical to God), and Leftow accepts 1–4 as sound only if 4 means this (ibid.).
