Whether God can do what He does not?

Objections

Objection 1 : It seems that God cannot do other than what He does. For God cannot do what He has not foreknown and pre-ordained that He would do. But He neither foreknew nor pre-ordained that He would do anything except what He does. Therefore He cannot do except what He does.
Objection 2 : Further, God can only do what ought to be done and what is right to be done. But God is not bound to do what He does not; nor is it right that He should do what He does not. Therefore He cannot do except what He does.
Objection 3 : Further, God cannot do anything that is not good and befitting creation. But it is not good for creatures nor befitting them to be otherwise than as they are. Therefore God cannot do except what He does.
