Abstract
In this paper I argue that the classic concept of eternity, as it is presented in Boethius, Anselm and Aquinas, must be understood to involve not only the claim that all temporal things are epistemically present to God, but also the claim that all temporal things areexistentially present to God insofar as they coexist timelessly in the eternal present. I further argue that the concept of eternity requires a tenseless view of time. If this is correct then the existence of an eternal God logically depends on the truth of the tenseless account of time. I conclude by suggesting that the Christian theologian ought to reject a tenseless ontology.
