Theophylact of Ohrid
Catena Aurea · Johannesevangelium 15
These things I command you, that ye love one another. If the world hate you, ye know that it hated me before it hated you. If ye were of the world, the world would love his own: but because ye are not of the world, but I have chosen you out of the world, therefore the world hateth you. 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. But all these things will they do unto you for my name’s sake, because they know not him that sent me.
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.
