Disturbed and heartsick, I grieve to learn of yet another respected Christian leader’s secret immoral life, especially for the wounded victims shattered in his wake. Perhaps Jude—the half-brother of Jesus, the younger son of Mary of Nazareth—would have discerned this because he wrote the book (literally) on how to spot ungodly people, as he calls them. So I turn to Jude’s tiny New Testament letter to help me make sense of what I see in the world.
