Can Creator create morality from nothing?

If God exists and He created morality, then that morality is by definition absolute and objective, since there can be no higher source to define it. The problems start however if God starts being capricious and altering morality for whatever reason. It then cannot be deemed to be eternal and absolute. I know you did not introduce the element of capriciousness into the equation, but it is very important nonetheless. But if we take your premise at face value then yes, morality is absolute and objective.

Or is it? Because then one has another problem and it is this: if God is omnipotent and omniscient, it does not automatically follow that He is also omnibenevolent. Omnibenevolence, unlike the other two, is not conditional on God's existence. You cannot be God and not be omnipotent or omniscient for example, as they are two requirements of an absolute and eternal deity. But He does not have to be omnibenevolent however. So his morality, even if not subject to capriciousness, can still be suspect. Now you may get round this by just claiming God is omnibenevolent, but unless you can reference said omnibenevolence as an absolute requirement of His existence like the other two, then your premise that absolute morality can exist as an ethical code of existence that cannot be improved upon, cannot be demonstrated.
