In defense of a supernatural foundation to morality: reply to Shermer

In my original paper, I claimed that our moral obligations are real, objective, and grounded in the supernatural. In particular, I endorsed the claim that God's will is the basis or source of our moral obligations, where "God" is to be understood as the theistic being who is omnibenevolent, omniscient, and omnipotent, who created the universe, and who is still actively involved in the universe after creating it. In his critical article, Michael Shermer has raised a number of important challenges to my view. Here I try to defend the position and respond to at least his most serious objections.
