I don't think it can used as an excuse for not having to act yourself. (Well, not if you want to be taken seriously ) It's been an excuse for not having to answer the question why god couldn't do a better job at this, or why evil exists in the first place. People use religion as an excuse far too often. I think that as soon as you act in the name of *insert name of god here*, you're on the wrong track. Actions should be taken in your own name because you're the only one responsible for them.
