Abstract Within the space of monotheistic options, trinitarian monotheism holds a puzzling place. It asserts that God is a single being who is, somehow, also three distinct persons. This form of monotheism has regularly been charged with being either inconsistent, unintelligible, or undermotivated – and possibly all three. While recent explorations of trinitarian monotheism have tended to rely on work in metaphysics, this paper turns to the philosophy of mind, showing that functionalist theories of mind prove to be surprisingly hospitable to trinitarian monotheism. This paper will address only the inconsistency and unintelligibility objections, showing that if role-functionalism (or something near enough) is both consistent and conceivable, then it is both consistent and conceivable that: God is a single being who is exactly three distinct persons because there is one primary divine person who interacts with exactly one system-sharing re-realisation of his own person-type.
