Moral arguments for God's existence have undergone something of a resurgence in recent years. For quite a while they were out of vogue for a variety of reasons, but recent advances in the philosophy of language and philosophical and natural theology have reinvigorated moral apologetics. This is the first book to consolidate these gains into one coherent treatment, which will rigorously demonstrate to a wide readership how effectively various objections to moral apologetics have been answered. The authors show how strides in answering the problem of evil, the Euthyphro Dilemma, and epistemic vacuity and arbitrariness challenges to theistic ethics make possible a compelling cumulative moral argument that can greatly contribute to the rational case for God's existence—and God's goodness. The authors hope to reach a readership of not just philosophers, apologists, and theologians, but bright college students up through graduate school and beyond. Christians and non-Christians alike, those interested in apologetics, moral theology, atheology, and morality and religious ethics should find the book a significant contribution to their field.
