Agnostic theism, also known as spiritual agnosticism, is the philosophical view that encompasses both theism and agnosticism. Per theism, an agnostic theist believes that the proposition at least one deity exists is true, but, per agnosticism, believes that the existence of gods are unknown or inherently unknowable. The agnostic theist may also or alternatively be agnostic regarding the properties of the god(s) they believe in.
