We all want to be happy. Every day, in whatever we do, we seek this goal. But what exactly is happiness? And how can we find it? The saints and psychologists agree: there can be no real happiness without authentic love. This work explores some of the most interesting and vexing issues concerning contemporary marriage, including contraception, reproductive technology, and divorce. Appealing to reason rather than religious authority, the book tackles the most controversial and talked about moral teachings of the Catholic Church and argues for their reasonableness. The book's interdisciplinary approach, following the precedent of Thomas Aquinas, looks to human happiness and fulfillment, properly understood, in seeking the answers to questions about how to live. It aims to show to skeptical readers that what the Catholic Church teaches about marriage is rationally justified by considering evidence from psychology, sociology, and philosophy. Professor Christopher Kaczor and his wife, Jennifer, explore the nature of covenant marriage and the love spouses promise to each other -- a self-giving love that is the choice to do good for the other. They also examine alternatives to covenant marriage, such as polygamy, same-sex "marriage", and cohabitation. Finally the book discusses the place of children within the family. To make sense of Catholic teaching on contraception, the Kaczors explain, we must first reconsider the value of having children. Hard-cover. 210 pages.
