Humanae Vitae

“The marriage of those who have been baptized is, in addition, invested with the dignity of a sacramental sign of grace, for it represents the union of Christ and His Church.”

Sacro autem baptismate ablutis, matrimonium eiusmodi praeditum est dignitate, ut gratiae sacramentale signum exsistat, cum Christi et Ecclesiae coniunctionem designet.
