Seems interesting. I fear that we will quickly end up having to come to acceptable definitions; such as, what precisely is meant by a moral theory.
Take for instance the moral theory of marriage as prescribed by the religious right in the U.S.: marriage is only permissible between one man and one woman. Those that espouse this certainly would consider it morally absolute; however, there are so many valid arguments against it that we would be safe in considering it relative. What if we considered the prohibition of an adult marrying a child? Would this be morally absolute? What is the proper age of consent? Is consent really dependent on age? What of the mentally handicapped? Are arranged marriages moral? If some answer no, what of the cases where all participants are willing?
