Sanctae Familiae Mariae Jesu Joseph: God was subject to man

From the Holy Gospel according to Luke
Luke 2:42-52
And when he was twelve years old, they going up into Jerusalem, according to the custom of the feast, And having fulfilled the days, when they returned, the child Jesus remained in Jerusalem; and his parents knew it not. And so on.

Homily of St. Bernard Abbot
Homilia super Missus est, n. 7-8
And he was subject unto them. Who was subject? And to whom? God to man! God, I repeat, to whom the Angels are subject, whom the Principalities and Powers do obey, was subject to Mary; and not only to Mary, but to Joseph also for Mary's sake. Marvel, therefore, both at God and man, and choose that which giveth greater wonder, whether it be the most loving condescension of the Son, or the exceeding great dignity of his Mother. Both amaze us, both are marvellous. That God should obey a woman is lowliness without parallel, that woman should rule over God, an elevation beyond comparison. In praise of virgins it is sung of them alone, that they follow the Lamb whithersoever he goeth. Of what praise do ye judge that woman to be worthy who is thus placed before the Lamb of God.
