The present paper deals with the issue of mutual submission of spouses that we find in 5th chapter of Ephesians in the context of Pius XI’s Casti connubi encyclical, st. John Paul II’s Original Unity of Man and Woman catecheses on marriage, and the Tradition of Church. It aims to deepen the understanding of the meaning of the relationship between a man and a woman in sacramental marriage and to draw attention to the continuity of the Church’s teaching on this issue before and after the Second Vatican Council.
