John Chrysostom

(Hom. lx. 1) Two evil persons have been mentioned, one that kills, and robs the sheep, another that doth not hinder: the one standing for those movers of seditions; the other for the rulers of the Jews, who did not take care of the sheep committed to them. Christ distinguishes Himself from both; from the one who came to do hurt by saying, I am come that they might have life; from those who overlook the rapine of the wolves, by saying that He giveth His life for the sheep. Wherefore He saith again, as He said before, I am the good Shepherd. And as He had said above that the sheep heard the voice of the Shepherd and followed Him, that no one might have occasion to ask, What sayest Thou then of those that believe not? He adds, And I know My sheep, and am known of Mine. (Rom. 11:12) As Paul too saith, God hath not cast away His people, whom He foreknew.
