He that speaks of himself seeks his own glory: but he that seeks his glory that sent him, the same is true, and no unrighteousness is in him.

He that speaketh of Himself, &c But on the other hand Cyril concludes with, "He who seeks not God"s glory but his own, is a liar, and full of deceit"—a liar, because under pretence of observing the law he puts forth his own will; and full of deceit, because he dares to prefer his own commands to those of God. This then is the second proof that Christ gives, that He speaks not of Himself. Put logically it is thus, He that speaks for Himself seeks his own glory. But I seek not my own glory; therefore I speak not of Myself. Heretics and philosophers teach their own opinions, and call their followers after their own names. For in either case, it is desire for fame which causes heresies and sects.
Unrighteousness, that is fraud, craft, deception, for Christ teaches sincerely and truly what he believes will please God and promote His glory, while others seek their own glory, and use flattery and other arts to extort it from men for themselves.
