This fourth and last of four study guides covers the sections of the Theology of the Body entitled The Sacramentality of Marriage and Reflections on Humanae Vitae.  This new study guide for the text of the Theology of the Body is designed to assist you in exploring the depths of John Paul II's theology and in applying his life-changing reflections to daily life. Anastasia Northrop gives a brief summary and overview of each audience, followed by thought-provoking questions to inspire lively and fruitful discussion for those using it in a group setting, and food for thought for those reading it on their own. Definitions are provided for John Paul II's tough vocabulary words. Included are recommendations for beginning and facilitating a study group.
