Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 2
But when Herod was dead, behold, an Angel of the Lord appeareth in a dream to Joseph in Egypt, Saying, Arise, and take the young Child and His mother, and go into the land of Israel; for they are dead which sought the young Child’s life. PSEUDO-DIONYSIUS. (De Cæl. Hierarch. 4.) See how Jesus Himself, though far above all celestial beings, and coming unchanged to our nature, shunned not that ordinance of humanity which He had taken on Him, but was obedient to the dispositions of His Father made known by Angels. For even by Angels is declared to Joseph the retreat of the Son into Egypt, so ordained of the Father, and His return again to Judæa.
See how Joseph was set for ministering to Mary; when she went into Egypt and returned, who would have fulfilled to her this so needful ministry, had she not been betrothed? For to outward view Mary nourished and Joseph defended the Child; but in truth the Child supported His mother and protected Joseph. Return into the land of Israel; for He went down into Egypt as a physician, not to abide there, but to succour it sick with error. But the reason of the return is given in the words, They are dead, &c.
