“If the name above every name was given by the Father to the Son, Who was God, and every tongue owned Him Lord, after the incarnation, because of His obedience, then before the incarnation He neither had the name above every name nor was owned by all to be Lord.  It follows then that after the incarnation He was greater than before the incarnation, which is absurd.”  So of Matt. xxviii. 18. “We must understand this of the incarnation, and not of the Godhead.”
