This is a catechetical resource from the Marriage: Unique for a Reason, an initiative of the U.S. Conference of Catholic Bishops' Subcommittee for the Promotion and Defense of Marriage. The initiative is to help catechize and educate Catholics on the meaning of marriage as the union of one man and one woman. The importance of marriage to the common good of society is explored in this video in view of the redefinition of marriage in the law.
