John Chrysostom

"Brethren, be ye imitators of me, and mark them which so walk even as ye have us for an ensample."

He had said above, "beware of dogs," from such he had led them away; he brings them near to these whom they ought to imitate. If any one, saith he, wishes to imitate me, if any one wishes to walk the same road, let him take heed to them; though I am not present, ye know the manner of my walk, that is, my conduct in life. For not by words only did he teach, but by deeds too; as in the chorus, and the army, the rest must imitate the leader of the chorus or the army, and thus advance in good order. For it is possible that the order may be dissolved by sedition.

The Apostles therefore were a type, and kept throughout a certain archetypal model. Consider how entirely accurate their life was, so that they are proposed as an archetype and example, and as living laws. For what was said in their writings, they manifested to all in their actions. This is the best teaching; thus he will be able to carry on his disciple. But if he indeed speaks as a philosopher, yet in his actions doth the contrary, he is no longer a teacher. For mere verbal philosophy is easy even for the disciple: but there is need of that teaching and leading which comes of deeds. For this both makes the teacher to be reverenced, and prepares the disciple to yield obedience. How so? When one sees him delivering philosophy in words, he will say he commands impossibilities; that they are impossibilities, he himself is the first to show, who does not practice them. But if he sees his virtue fully carried out in action, he will no longer be able to speak thus. Yet although the life of our teacher be careless, let us take heed to ourselves, and let us listen to the words of the prophet; "They shall be all taught of God." (Isa. liv. 13) "And they shall teach no more every man his brother, saying, Know the Lord, for they shall all know me from the least of them to the greatest of them." (Jer. xxxi. 34) Hast thou a teacher who is not virtuous? Still thou hast Him who is truly a Teacher, whom alone thou shouldest call a Teacher. Learn from Him: He hath said, "Learn of Me, for I am meek." (Matt. xi. 29) Take not heed, then, to thy teacher, but to Him and to His lessons. Take thence thy examples, thou hast a most excellent model, to it conform thyself. There are innumerable models laid before thee in the Scriptures of virtuous lives; whichsoever thou wilt, come, and after the Master find it in the disciples.
