Theistic morality

[Purple Rabbit]

Ah, so morality isn't just what society believes, but has an underlying utilitarian justification.

At some point the underlying justification is what society "believes", it's relative just the same.

You confused me by referring to your view as 'moral relativism', which is generally the view that morality is relative to society's view. It seems your view would be better described as moral consequentialism, the view that morality is judged by an action's consequences. This seems like a very sensible approach to me.

The view I described is a moral relativism because its acceptance still depends on shared opinion.

Relative to the situation, yes. Not to anything else, like society's opinion.

Of course it is dependent on society's opinion, the shared opinion whether the rationale is valid or not. If it was not dependent on society's opinion, every society would have the same rationale which is not the case.
