God's Plan for a Joy-Filled MarriageChristopher West
God's Plan for a Joy-Filled Marriage is a new, supplemental marriage preparation program by renowned Catholic author and teacher Christopher West. Based on Pope John Paul II's revolutionary Theology of the Body and the book Good News About Sex & Marriage, this program has a two-fold goal: to present a summary of Catholic teaching on God's plan for marriage, and to offer engaged couples practical suggestions for embracing this plan in their own lives. The Holy Father teaches that human life's dignity and balance depends at every moment on ?who woman will be for man and who man will be for woman.? God's plan of life and love is literally stamped in our bodies. Here, you will find a much-needed testimony to the essential interrelation between love, life, and sexuality, and discover how a deep appreciation for this interrelation is the path to a blessed and joy-filled marriage. The Theology of the Body has been called "one of the boldest reconfigurations of Catholic Theology in centuries," according to George Weigel, the pope's official biographer. It addresses some of the most fundamental and important questions of human existence, including: Why were we created male and female? Where do we come from and why? What is the meaning of life? How do we experience it? Why is there evil in the world and how do we overcome it? The God's Plan workbook and the DVD series are perfect for Marriage Prep classes or for use as a supplement with an existing Pre-Cana program.

Theology of the Body for BeginnersChristopher West
What is the "Theology of the Body"? According to Pope John Paul II, if we live according to the true meaning of our sexuality, we "fulfill the very meaning of [our] being and existence." The human body is a "theology" because it is meant to be a sign of God's own life and love in the world. With clarity and precision, Christopher West unpacks John Paul II's Theology of the Body, translating it into a language everyone can understand.
