From the perspective of developmental psychology, this book examines human sexuality and celibate chastity over the course of a lifetime. Issues such as identity, intimacy, relationships, genital, gender, and sex role identity, and sexual orientation are explored as well as the spiritual foundation upon which celibate chastity must rest. The author aims to help men and women who have embraced a life of celibate chastity to understand better this way of being a sexual person. The book, though, has a much wider audience than Catholic priests and men and women religious. People of all faiths, living the single life, may feel called to just such a lifestyle. The ideas presented in this book will enrich their reflection about this important dimension of their life and add a significant new contribution to today's ongoing conversation about the topic.
