Encyclical Quamquam Pluries
His Holiness Pope Leo XIII
August 15, 1889
. . . in giving Joseph the Blessed Virgin as spouse, God appointed him to be not only her life's companion, the witness of her maidenhood, the protector of her honor, but also, by virtue of the conjugal tie, a participator in her sublime dignity.
And Joseph shines among all mankind by the most august dignity, since by divine will, he was the guardian of the Son of God and reputed as His father among men. Hence it came about that the Word of God was humbly subject to Joseph, that He obeyed him, and that He rendered to him all those offices that children are bound to render to their parents . . .
