1 That it is possible then to make use of deceit for a good purpose, or rather that in such a case it ought not to be called deceit, but a kind of good management worthy of all admiration, might be proved at greater length; but since what has already been said suffices for demonstration, it would be irksome and tedious to lengthen out my discourse upon the subject. And now it will remain for you to prove whether I have not employed this art to your advantage.
Basil: And what kind of advantage have I derived from this piece of good management, or wise policy, or whatever you may please to call it, so as to persuade me that I have not been deceived by you?
Chrysostom: What advantage, pray, could be greater than to be seen doing those things which Christ with his own lips declared to be proofs of love to Himself? For addressing the leader of the apostles He said, “Peter, do you love me?” and when he confessed that he did, the Lord added, “if you love me tend my sheep.” The Master asked the disciple if He was loved by him, not in order to get information (how should He who penetrates the hearts of all men?), but in order to teach us how great an interest He takes in the superintendence of these sheep. This being plain, it will likewise be manifest that a great and unspeakable reward will be reserved for him whose labors are concerned with these sheep, upon which Christ places such a high value. For when we see any one bestowing care upon members of our household, or upon our flocks, we count his zeal for them as a sign of love towards ourselves: yet all these things are to be bought for money:— with how great a gift then will He requite those who tend the flock which He purchased, not with money, nor anything of that kind, but by His own death, giving his own blood as the price of the herd. Wherefore when the disciple said, “You know Lord that I love You,” and invoked the beloved one Himself as a witness of his love, the Saviour did not stop there, but added that which was the token of love. For He did not at that time wish to show how much Peter loved Him, but how much He Himself loved His own Church, and he desired to teach Peter and all of us that we also should bestow much zeal upon the same. For why did God not spare His only-begotten Son, but delivered Him up, although the only one He had? It was that He might reconcile to Himself those who were disposed towards Him as enemies, and make them His peculiar people. For what purpose did He shed His blood? It was that He might win these sheep which He entrusted to Peter and his successors. Naturally then did Christ say, “Who then is the faithful and wise servant, whom his lord shall make ruler over His household.” Again, the words are those of one who is in doubt, yet the speaker did not utter them in doubt, but just as He asked Peter whether he loved Him, not from any need to learn the affection of the disciple, but from a desire to show the exceeding depth of his own love: so now also when He says, “Who then is the faithful and wise servant?” he speaks not as being ignorant who is faithful and wise, but as desiring to set forth the rarity of such a character, and the greatness of this office. Observe at any rate how great the reward is— “He will appoint him,” he says, “ruler over all his goods.”
