1 Hence it follows that God is not only the cause of 2 things coming into existence, but also of their continuing in 3 existence, that is, in scholastic phraseology, God is cause of 4 the being of things (essendi rerum). For whether things exist, 5 or do not exist, whenever we contemplate their essence, we see 6 that it involves neither existence nor duration; consequently, 7 it cannot be the cause of either the one or the other. God must 8 be the sole cause, inasmuch as to him alone does existence 9 appertain. (Prop. xiv. Coroll. i.) Q.E.D. 10 11
