Abstract
R. T. Mullins has questioned the tenability of a model of divine eternity according to which God exists timelessly sans creation and temporally since the moment of creation. His puzzlement about the model can be largely resolved by recognizing that two different understandings of causation may be applied to the origin of the universe, a medieval understanding of efficient causation by a causal agent and a modern understanding of causation as a relation between two events. Mullins’s more fundamental reservations about a relational theory of time can be resolved by allowing an event to occur at a moment or by defining “change” in such a way that a change need not occur over two moments of time. Finally, Mullins needs to do more to justify his own model involving an undifferentiated, successionless, precreation time.
