 To show how, Stump and Kretzmann coin the notion of Eternal-Temporal Simultaneity (“ET-simultaneity”). First, define an “eternal present” to be an infinitely extended, pastless, futureless duration (strictly speaking, on the terminology used here, it should be “timeless present”). Then let Temporal Simultaneity (“T-simultaneity”) be existence/occurrence at the same time, and let Eternal Simultaneity (“E-simultaneity”) be existence/occurrence at the same eternal present. Each involves only one mode of existence, namely either the temporal or the eternal. ET-simultaneity, by contrast, relates items in different modes of existence, one temporal, and one eternal.
