This brief book, excerpted from the papal exhortation Amoris Laetitia, distills for those about to be married, just married, or living their marriage, the essence of the value of a lifelong union and the beauty of the vocation to marriage. In addition, Pope Francis speaks of the reality of family and of children, who are a living reflection of the couple's love, a permanent sign of their conjugal unity, and a living and inseparable synthesis of their being a father and a mother.
