Couldn't help but oversee your conversation with Glen.
We live in a funny world, we read Plato last week for PHIL, and this week we're reading Meditations. 0.o It's a conspiracy!
Anyway, we tackled a similar problem in class. Is good good because God so commands it? Or is God commanding it because it is good? Either way there are some uneasy assumptions.
But our professor seems to have solved it pretty well.
First off, one must accept that morality is agent-based, not act-based. That is, morality is more about the character of a person. If a man led a perfectly good life, but had evil thoughts of anger and hatred in his mind all the time, he is definitely not as moral as the man who le\d a perfectly good life and had a perfectly good mind. See, it's not the actions, it's the character.
Now, according to Plato what people consider "moral actions" actually flow from a moral character. You do not shuffle threw your little file cabinet for the "right thing to do" every time you have to make a decision (as my prof would put it). If you are a moral person, you naturally want to do what your nature dictates you do, thus your actions are moral because you are a moral person. A moral person would naturally act according to their nature, not necessarily because of some outside standard.
God is good. That is simply His nature. Naturally He commands us according to His nature. He commands what is good because that’s simply who He is. He doesn’t have a list of “to do and not to dos” which He has to refer to. Goodness is not an outside standard. And good is not good merely because He says so, it is good because of who He is. Good is His nature, and His commands merely reflect that.
Did that sound like completely random ramblings or did it actually make some sense? (If I were actually able to make sense, my prof would be so proud of me!)
