John Chrysostom — as excerpted in the Catena Aurea on Mark 10:28-31

“(Hom. in Matt. 64) But it seems to me that by these words He intended covertly to proclaim that there were to be persecutions, as it would come to pass that many fathers would allure their sons to impiety, and many wives their husbands.1 Again He delays not to say, for my name’s sake and the Gospel’s, as Mark says, or for the kingdom of God, as Luke says; the name of Christ is the power of the Gospel, and of His kingdom; for the Gospel is received in the name of Jesus Christ, and the kingdom is made known, and comes by His name.”
