Thus Spake the Philosopher

Here's something rather pithy I found in Aristotle's Nicomachean Ethics.

It is to be noted that nothing that is past is an object of choice, e.g. no one chooses to have sacked Troy; for no one deliberates about the past, but about what is future and capable of being otherwise, while what is past is not capable of not having taken place; hence Agathon is right in saying
For this alone is lacking even to God,
To make undone things thathave once been done.

I think Aristotle makes an incorrect claim about God here, in as much as I will affirm the traditional Christian notion that God is the creator of, and hence above, time. In that context, it is really irrelevant to speak in terms of what has already occurred when referring to God. Thoughts?
