James McGrath does not express Christian moral obligations in the same terms I do, but [he agrees that various conceptions of Christian "objective" morality are problematic]. My favorite quote:
And so perhaps, instead of trying to prove that morality is objective, we should be working to make it objective, if morality is something we are concerned about.
Whether subjective or objective, get that plank out of your own eye first.
