He said not, Blessed are they who suffer persecution of the Gentiles; that we may not suppose the blessing pronounced on those only who are persecuted for refusing to sacrifice to idols; yea, whoever suffers persecution of heretics because he will not forsake the truth is likewise blessed, seeing he suffers for righteousness.
Moreover, if any of the great ones, who seem to be Christians, being corrected by you on account of his sins, shall persecute you, you are blessed with John the Baptist. For if the Prophets are truly martyrs when they are killed by their own countrymen, without doubt he who suffers in the cause of God has the reward of martyrdom though he suffers from his own people.
Scripture therefore does not mention the persons of the persecutors, but only the cause of persecution, that you may learn to look, not by whom, but why you suffer.
