5.  And again, “My Father is greater than I.” John xiv. 28.  This passage is also employed by the ungrateful creatures, the brood of the evil one.  I believe that even from this passage the consubstantiality of the Son with the Father is set forth.  For I know that comparisons may properly be made between things which are of the same nature.  We speak of angel as greater than angel, of man as juster than man, of bird as fleeter than bird.  If then comparisons are made between things of the same species, and the Father by comparison is said to be greater than the Son, then the Son is of the same substance as the Father.  But there is another sense underlying the expression.  In what is it extraordinary that He who “is the Word and was made flesh” John i. 14. confesses His Father to be greater than Himself, when He was seen in glory inferior to the angels, and in form to men?  For “Thou hast made him a little lower than the angels,” Ps. viii. 5. and again “Who was made a little lower than the angels,” Heb. ii. 9. and “we saw Him and He had neither form nor comeliness, his form was deficient beyond all men.” Isa. liii. 2, 3, LXX.  All this He endured on account of His abundant loving kindness towards His work, that He might save the lost sheep and bring it home when He had saved it, and bring back safe and sound to his own land the man who went down from Jerusalem to Jericho and so fell among thieves. cf. Luke x. 30.  Will the heretic cast in His teeth the manger out of which he in his unreasonableness was fed by the Word of reason?  Will he, because the carpenter’s son had no bed to lie on, complain of His being poor?  This is why the Son is less than the Father; for your sakes He was made dead to free you from death and make you sharer in heavenly life.  It is just as though any one were to find fault with the physician for stooping to sickness, and breathing its foul breath, that he may heal the sick.
