Generally, I agree with what you’ve said.

For myself, though, the concern with real and relativism that you expressed is misplaced and overblown. Relativism is a concern that absolutist usually voice—I mean, relativism presupposes an absolute point that one can be relative to. I presume neither relativism nor absolutism—I say that we are all embedded in communities of faith and practice. Nowhere in the Bible does the concern for real and relativism take shape. Both are basically modern concerns. I would add that in concrete practice, “everything is all right” isn’t a genuine concern—opposition practically always emerges around small and large issues. Hence, I say that ultimately people must persuade and fight for what they believe is right, good and moral. There is no external foundation, but there are people who will disagree and fight. In practice, “relativism” and “absolutism” are rhetorical tropes used in the fight to establish some vision of morality over another.
