The Epistle
The epistle is taken from St. Paul's letter to the Ephesians (5:20-33). It presents the cornerstone of the Christian vision of marriage: the love of man and woman parallels the love of Christ and the Church. As Christ gives Himself totally to and for His Church, so the husband is to give himself totally to and for his wife. As the Church, in turn, is subject to Christ, so the wife subjects herself to her husband. Thus the two become one in a life of mutual love and mutual subjection to each other in Christ.
