John Chrysostom

"Being filled with the fruits of righteousness which are through Jesus Christ unto the glory and praise of God;" i.e. holding, together with true doctrine, an upright life.

And not merely upright, but "filled with the fruits of righteousness." For there is indeed a righteousness not according to Christ, as, for example, a moral life. "Which are through Jesus Christ to the glory and praise of God." Seest thou that I speak not of mine own glory, but the righteousness of God; and oftentimes he calls mercy itself too righteousness; let not your love, he says, indirectly injure you, by hindering your perception of things profitable, and take heed lest you fall through your love to any one. For I would indeed that your love should be increased, but not so that ye should be injured by it. And I would not that it should be simply of prejudice, but upon proof whether I speak well or no. He says not, that ye may take up my opinion, but that ye may "prove" it. He does not say outright, join not yourself to this or that man, but, I would that your love should have respect to what is profitable, not that ye should be void of understanding. For it is a foolish thing if ye work not righteousness for Christ's sake and through Him. Mark the words, "through Him." Does he then use God as a mere assistant? Away with the thought. Not that I may receive praise, says he, but that God may be glorified.
