The sexual revolution brought a terribly distorted vision of the body and sex into the mainstream. How should Christians respond? With his illuminating Theology of the Body, Pope John Paul II challenged the modern world not to stop at the surface, but to enter the depth of the "great mystery" that the body and sex reveal: a mystery that lies at the heart of the Gospel itself. Since he first discovered John Paul II's teaching in 1993, Christopher West has devoted himself to sharing its life-transforming message with the world. In this highly anticipated work, West leads us into the depth of Christ's "nuptial union" with the Church, demonstrating how authentic Catholic teaching on the body and sex saves us from both the libertine perspective of popular culture and the cold puritanism that has sometimes infected Christianity. In the process, West provides a blueprint for reaching our sexually broken world in the "new evangelization."
