In this paper, I will offer an analogy between the Trinity and extended simples that supports a Latin approach to the Trinity. The theoretical tools developed to discuss and debate extended simples in the literature of contemporary analytic metaphysics, I argue, can help us make useful conceptual distinctions in attempts to understand what it could be for God to be Triune. Furthermore, the analogy between extended simples and the Trinity might surprise some who find one of these at least plausibly (...) possible and the other incoherent. (shrink)

Roughly, the problem of the Trinity is the problem of how God can be one and yet be the Father, the Son, and the Holy Spirit, which are three, not one. That one thing is identical with three distinct things seems to violate traditional laws of identity. I propose a solution to this problem according to which it is just an ordinary claim of one-many identity. For example, one pair of shoes is identical with two shoes; and my one body (...) is identical with its six limbs of arms, legs, head, and torso. The pair of shoes is not identical with each one of the two shoes, nor is my body identical with each one of its six limbs, but rather identical with all of them taken together, or collectively. I argue that the problem of the Trinity should be understood accordingly: God is identical with the Father, the Son, and the Holy Spirit collectively, but not with each one of them distributively. According to the way I develop this proposal, no traditional laws of identity are violated, but merely generalized in an intuitive way. I argue that this is compatible with Christian Orthodoxy as given by the Athanasian Creed. I end by responding to some anticipated objections. (shrink)

Relative-identity theories of the Trinity and Incarnation are worth another look. But not all such theories are the same. One important difference among them concerns restricted quantification. Peter Geach proposes two theses: the sortal relativity of identity and the irreducibility of restricted quantification. Every relative-identity theory of the Trinity and Incarnation applies Geach’s first thesis. But only what I call “the Geachian theory” applies both theses. I argue that any such Geachian theory faces significant theoretical disadvantages. Towards the end, I (...) propose a closely related but non-Geachian relative-identity theory that doesn’t share those theoretical disadvantages. (shrink)

I have used a time travel story to model the “Latin” version of the Trinity. William Hasker’s “A Leftovian Trinity?” criticizes my arguments. This piece replies.

Jeffrey Brower and Michael Rea have proposed a model for the Trinity using a particular understanding of the relation of material constitution. I examine this model in detail and conclude that it cannot succeed. I then suggest, but do not fully develop, a model of the Trinity using an alternative notion of constitution.

This paper discusses how the possibility of multi-located entities can resolve problems both with the Trinity and with the existence of souls.

This paper employs recent developments in the theory of truthmakers to offer a novel solution to the most discussed philosophical challenge presented by the Christian doctrine of the Trinity. According to the view developed, the Father, Son, and Spirit each serve as the only substantial constituent of equally minimal truthmakers for claims about God. Because they do, there is a clear and robust sense in which each is a substance that “is” God as much as anything is, while the three (...) remain distinct from each other. The view is shown to hold certain prima facie advantages over rival extant approaches. (shrink)
