John 15:20

"The servant is not greater than his lord. If they have persecuted Me, they will also persecute you." He showed that in this point they would be most His imitators. For while Christ was in the flesh, men had war with Him, but when He was translated, the battle came in the next place upon them. Then because owing to their fewness they were terrified at being about to encounter the attack of so great a multitude, He raiseth their souls by telling them that it was an especial subject of joy that they were hated by them; "For so ye shall share My sufferings. Ye should not therefore be troubled, for ye are not better than I," as I before told you, "The servant is not greater than his lord." Then there is also a third source of consolation, that the Father also is insulted together with them.

(Tract. lxxxviii. 1) Our Lord, in exhorting His servants to bear patiently the hatred of the world, proposes to them an example than which there can be no better and higher one, viz. Himself: Remember the word that I said unto you, The servant is not greater than his lord. If they have persecuted Me, they will also persecute you: if they have kept My saying, they will keep yours also. (Tract. lxxxviii. 1) The servant is not greater than his Lord. Here the servant is the one who has the purified fear, which abideth for ever.

The Lord, in exhorting His servants to endure with patience the hatred of the world, proposes to them no greater and better example than His own; seeing that, as the Apostle Peter says, "Christ suffered for us, leaving us an example, that we should follow His steps." And if we really do so, we do it by His assistance, who said, "Without me ye can do nothing." But further, to those to whom He had already said, "If the world hate you, know that it hated me before it hated you," He now also says in the word you have just been hearing, when the Gospel was read, "Remember my word that I said unto you, The servant is not greater than his lord: if they have persecuted me, they will also persecute you; if they have kept my saying, they will keep yours also." Now in saying, "The servant is not greater than his lord," does He not clearly indicate how He would have us understand what He had said above, "Henceforth I call you not servants"? For, you see, He calleth them servants. For what else can the words imply, "The servant is not greater than his lord: if they have persecuted me, they will also persecute you"? It is clear, therefore, that when it is said, "Henceforth I call you not servants," He is to be understood as speaking of that servant who abideth not in the house for ever, but is characterized by the fear which love casteth out; whereas, when it is here said, "The servant is not greater than his lord: if they have persecuted me, they will also persecute you," that servant is meant who is distinguished by the clean fear which endureth for ever. For this is the servant who is yet to hear, "Well done, thou good servant: enter thou into the joy of thy Lord."

Or thus: If, Me says, they have persecuted your Lord, much more will they persecute you; if they had persecuted Him, but kept His commandments, they would keep yours also.

They observed it in order to calumniate it, as we read in the Psalms, The ungodly seeth the righteous.
