13 “Nevertheless among the chief rulers also many believed on Him; but, because of the Pharisees, they did not confess Him, lest they should be put out of the synagogue: for they loved the glory of men more than the glory of God.” See how the evangelist marked and disapproved of some, who yet, he said, believed on Him: who, if ever they did advance though this gateway of faith, would thereby also overcome that love of human glory which had been overcome by the apostle, when he said, “God forbid that I should glory, save in the cross of our Lord Jesus Christ, by whom the world is crucified unto me, and I unto the world.” For to this end also did the Lord Himself, when derided by the madness of human pride and impiety, fix His cross on the foreheads of those who believed on Him, on that which is in a manner the abode of modesty, that faith may learn not to blush at His name, and love the glory of God more than the glory of men.
