Thank you for your responses. Some thoughts in reply:
Running Man: I noticed that you fail to quote any of the New Testament in your post. You do qoute from the old testament in part but you fail to put these events in context, nor do you mention the consequences of the behavior that some of the men you mention engaged in. David for example paid a huge price for his sins. You also fail to mention the biggest principle of the Christian faith and that is forgiveness for our sins by the same God who you call cruel.
It seems that without a moral code that is based on any standard that an aethist will develop a personal moral code that seems right for him. This of course leads to everyone doing what they want and telling everyone else to let them. If it is based upon culture alone, than if a culture allowed murder and rape without consequences you would have to say that that is alright. If everyone can do what they want, why would an aethist attempt to impose the morality of their culture on another culture, such as when the government imposes sanctions on another country for "human rights" violations. It would appear hypocritical for an aethist who has devloped his own moral code to support such an action.
Larc, some folks may go to church in an attempt to stay moral, however I don't believe that is the reson the majority go. We go to worship our God, learn his word and fellowship with fellow believers.
