Today's conflicts between religions are grounded largely in historical injustices and grievances but partly in serious conceptual disagreements. This essay agrees with Miroslav Volf that a nontritheistic Christian account of the Trinity is highly desirable. Three traditional models of the Trinity are examined. In their pure, unmixed form, two of them should logically be acceptable to Jews, Muslims, and strict monotheists who regard Christianity as inherently tritheistic, despite lip service to one God. In the social model, three distinct self-aware subjects (...) are unified by being in perfect harmony with each other. Despite Volf's best defense of this, to conceive of three gods, this is how one would go about it. In the psychological model, one divine subject has three psychological capacities—memory, understanding, and will. In the functional model, one subject relates to the world in three different ways—as creator, redeemer, and companion. These two are genuinely monotheistic. Finally, a monotheistic account of the unity of Jesus with God is proposed for consideration. (shrink)

In this thesis, I argue that the Functional Monotheism model is not tri-theistic, but is a model of pro-Nicene Trinitarianism. In establishing this thesis, I focus on countering a specific objection prevalent in the Analytic Theology literature; the Tri-Theism Objection, which has charged the Functional Monotheism model with “tri-theism”. This objection, formulated by Kelly James Clark and Edward Feser, asserts that the Functional Monotheism model is tritheistic and thus should be rejected as a possible model of scriptural monotheism and “orthodox” (...) Trinitarianism. I argue against this objection by demonstrating that the Functional Monotheism model, once certain necessary philosophical clarifications and modifications are made, is not tri-theistic (in the classical sense of the term), but is in fact in line with “strict” (Second Temple) Jewish monotheism and “orthodox” (pro-Nicene) Trinitarianism. The Functional Monotheism model, contra the proponents of the objection, is therefore not subject to a charge of tri-theism, and thus should be taken as a viable model of “orthodox” Trinitarianism that can aid analytic theologians in their Trinitarian theorising.
