This treatise explores both the beguiling fancy that without God, moral virtue is not possible, and the dream that human fulfillment awaits the faithful in an afterlife Kingdom. It shows that Jesus’ Parables of the Kingdom of God, once stripped of their deceptive theological overlay, reveal an account of real-time flourishing that is secular, constituted by virtue, and incompatible with the life of faith (total dedication to a deity). Part I establishes that morality and human virtue are indeed fully independent of God’s very existence, while Parts II and III isolate the prized hermeneutical principle whereby the authentic words of Jesus are set in relief. What emerges is Jesus’ own urgent testimony of a this-world kingdom which is the good-life for humans—the summum bonum. This vision, anchored in the very tradition of which Jesus was both participant and critic, reveals human fulfillment as an achievement which is possible only here and now—should we muster the courage to live it.
