Pseudo-Dionysius the Areopagite

(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.
