 As we shall see, there are a variety of features of morality that can be appealed to in the first steps of the arguments, as well as a variety of ways in which God might be thought to provide an explanation of those features in the second steps. The use of the somewhat vague phrase “objective moral facts” is intended to allow for this variety in Premise 1. The similarly vague notion of God providing the best explanation of such facts allows for the variety of ways moral features may depend on God—divine commands one salient option among them. Both types of premises are obviously open to challenge. For example, the first premise of such an argument can be challenged by popular metaethical views that see morality as “subjective,” or “expressive,” rather than something that consists of objective facts. Moral skeptics and “error theorists” also challenge the first premise. The second premise can be challenged on the basis of rival explanations of the features of morality, explanations that do not require God. Arguments about the second premise then may require comparison between theistic explanations of morality and these rival views, with an attentive eye on the relevant evidence in need of explanation.
