In this collection of texts, Father Kentenich explores life-defining questions related to human sexuality and the virtue of purity. He considers the God-willed role of the drives in general and the sex drive in particular, what it means to be man and woman, and the unique features of the celibate and married vocations. He explores the topic from the ethical, pedagogical, and theological perspectives, and sheds light on the special role that Mary, the Mother of God, can play in bringing harmony to this often conflicted area of life. The texts in this book have been selected to give a broad context for appreciating the gift of human sexuality and the gift of purity.
