Why does the Catholic Church care so much about marriage?
The Catholic Church cares about marriage because marriage is a fundamental good in itself and foundational to human existence and flourishing. Following the example of Jesus, the Church cares about the whole person, and all people. Marriage (or the lack thereof) affects everyone. Today, people all over the world are suffering because of the breakdown of the family – divorce, out-of-wedlock childbearing, and so on.
Marriage is never just a “private” issue; it has public significance and public consequences. One only has to think of the connection between fatherless families and young men in jail to know that this is true. In addition, the proposal to “redefine” marriage to include two men or two women is really a proposal to “redefine” the human person, causing a forgetfulness of what it means to be a man or a woman. This is a basic injustice to men and women, children, and fathers and mothers. Marriage is truly one of the most important social justice issues of our time.
