In this paper, I consider the philosophical consequences of one tradition in Trinitarian theology, which emphasizes that each of the persons of the Trinity is wholly God. I pay special attention to Leftow’s claim that the persons of the Godhead must be divine in the same sense of the word ‘divine’ as the Godhead itself. I argue that the existing philosophical account of the Trinity which best captures this view is what I have termed the ‘Strong Theory of Relative Identity,’ (...) first proposed Peter Geach. I then develop what I take to be the most pressing objection to this account of the Trinity, namely that it cannot be supplemented with a coherent model-theoretic semantics. I end with a suggestion for responding to this objection. (shrink)

In this article I object to Le Poidevin's contention that relative identity is beset with an infinite metaphysical regress. I argue, first, that since Le Poidevin's regress argument presupposes a direct theory of reference, it does not apply to accounts of relative identity which reject this account of reference. I argue, second, that Le Poidevin's regress is not inevitable for one who accepts a direct account of reference, since it does not apply to the formal logic of relative identity which (...) van Inwagen uses to articulate and defend the mysteries of the Trinity and the Incarnation.
