Whether God can annihilate anything?

Objections

Objection 1 : It would seem that God cannot annihilate anything. For Augustine says (Questions. 83, qu. 21) that "God is not the cause of anything tending to non-existence." But He would be such a cause if He were to annihilate anything. Therefore He cannot annihilate anything.
Objection 2 : Further, by His goodness God is the cause why things exist, since, as Augustine says (De Doctr. Christ. i, 32): "Because God is good, we exist." But God cannot cease to be good. Therefore He cannot cause things to cease to exist; which would be the case were He to annihilate anything.
Objection 3 : Further, if God were to annihilate anything it would be by His action. But this cannot be; because the term of every action is existence. Hence even the action of a corrupting cause has its term in something generated; for when one thing is generated another undergoes corruption. Therefore God cannot annihilate anything.
