Show me the money

The idea of re-writing the Ten Commandments to reflect modern language and thought has much to commend it, although replacing "thou shalt not steal" by "prosper with a clear conscience" seems to me to be rather dodging the issue, but the thing that struck a decidedly bum note with me is that, if you want to study these new Commandments it will cost you.  You'll have to shell out for a book or DVD or "tool kit" - anything from £30 upwards.  I don't recall God charging Moses.  Is this prospering with a clear conscience?
