A dear friend of mine who has abandoned Christian belief to become an agnostic naturalist has challenged me to set forth an absolute Biblical ethic to counter his relative, culture-based ethic. He maintains that the Scriptures present a contradictory account of what is right and wrong, and that there are no truly absolute ethics - even if we look to the Bible as the standard. After I began to present an absolute Biblical ethic based on the Law/Gospel distinction and the twin concepts of love for God as the ultimate good and sin against God as the ultimate evil, and as I was building upon these ideas, my friend replied that if there is no God then this ethic is meaningless and useless. My reply to that:
I don't know if my answers are any good for my friend, although I believe they reflect Truth. What would you say to a friend who has turned from the faith but still wants to talk to you about it?
