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. John 15:18-21

Persecution of the early Christians under emperors Diocletuian and Maximilian, A.D. 301

From Syria even unto Rome I fight with wild beasts, by land and sea, by night and by day, being bound amidst ten leopards, even a company of soldiers, who only wax worse when they are kindly treated. Howbeit through their wrong doings I become more completely a disciple. Ignatius: to the Romans (A.D. 35-105) ch.5

And why then have I delivered myself over to death, unto fire, unto sword, unto wild beasts? But near to the sword, near to God; in company with wild beasts, in company with God. Only let it be in the name of Jesus Christ, so that we may suffer together with Him. Ignatius: to the Smyrnaeans (A.D. 35-105) ch.4

"And from the eleventh mountain, where were trees full of fruit, decked with divers kinds of fruits, they that believed are such as these; they that suffered for the Name [of the Son of God], who also suffered readily with their whole heart, and yielded up their lives."… "Listen," said he; "all as many as ever suffered for the Name's sake are glorious in the sight of God, and the sins of all these were taken away, because they suffered for the name of the Son of God. Now hear why their fruits are various, and some surpassing others." Hermas (A.D. 150) Ante-Nicene Fathers vol.2 pg.52

But you that suffer for the Name's sake ought to glorify God, because God deemed you worthy that you should bear this name, and that all your sins should be healed. Reckon yourselves blessed therefore; yea, rather think that you have done a great work, if any of you shall suffer for God's sake. The Lord bestows life upon you, and you perceived it not; for your sins weighed you down, and if you had not suffered for the Name [of the Lord], you had died unto God by reason of your sins. Hermas (A.D. 150) Ante-Nicene Fathers vol.2 pg.52

And those among yourselves who are accused you do not punish before they are convicted; but in our case you receive the name as proof against us, and this although, so far as the name goes, you ought rather to punish our accusers. For we are accused of being Christians, and to hate what is excellent is unjust. Again, if any of the accused deny the name, and say that he is not a Christian, you acquit him, as having no evidence against him as a wrong-doer; but if any one acknowledge that he is a Christian, you punish him on account of this acknowledgment. Justin Martyr (A.D. 160) Ante-Nicene Fathers vol.1 pg.164

And reckon you that it is for your sakes we have been saying these things; for it is in our power, when we are examined, to deny that we are Christians; but we would not live by telling a lie. For, impelled by the desire of the eternal and pure life, we seek the abode that is with God, the Father and Creator of all, and hasten to confess our faith, persuaded and convinced as we are that they who have proved to God by their works that they followed Him. Justin Martyr (A.D. 160) Ante-Nicene Fathers vol.1 pg.165

And if you also read these words in a hostile spirit, you can do no more, as I said before, than kill us; which indeed does no harm to us, but to you and all who unjustly hate us, and do not repent, brings eternal punishment by fire. Justin Martyr (A.D. 160) Ante-Nicene Fathers vol.1 pg.178

For we do not fear death, since it is acknowledged we must surely die; and there is nothing new, but all things continue the same in this administration of things; and if satiety overtakes those who enjoy even one year of these things, they ought to give heed to our doctrines, that they may live eternally free both from suffering and from want. But if they believe that there is nothing after death, but declare that those who die pass into insensibility, then they become our benefactors when they set us free from sufferings and necessities of this life, and prove themselves to be wicked, and inhuman, and bigoted. For they kill us with no intention of delivering us, but cut us off that we may be deprived of life and pleasure. Justin Martyr (A.D. 160) Ante-Nicene Fathers vol.1 pg.182

But if this idea take possession of some one that if we acknowledge God as our helper, we should not, as we say, be oppressed and persecuted by the wicked; this, too, I will solve…Wherefore God delays causing the confusion and destruction of the whole world, by which the wicked angels and demons and men shall cease to exist, because of the seed of the Christians, who know that they are the cause of preservation in nature. Justin Martyr (A.D. 160) Ante-Nicene Fathers vol.1 pg.190

Now it is evident that no one can terrify or subdue us who have believed in Jesus over all the world. For it is plain that, though beheaded, and crucified, and thrown to wild beasts, and chains, and fire, and all other kinds of torture, we do not give up our confession; but the more such things happen, the more do others and in larger numbers become faithful, and worshippers of God through the name of Jesus. For just as if one should cut away the fruit-bearing parts of a vine, it grows up again, and yields other branches flourishing and fruitful; even so the same thing happens with us. Justin Martyr (A.D. 160) Ante-Nicene Fathers vol.1 pg.254

When, again, He says, "When they persecute you in this city, flee you to the other," He does not advise flight, as if persecution were an evil thing; nor does He command them by flight to avoid death, as if in dread of it, but wishes us neither to be the authors nor abettors of any evil to any one, either to ourselves or the persecutor and murderer. For He, in a way, bids us take care of ourselves. But he who disobeys is rash and foolhardy. If he who kills a man of God sins against God, he also who presents himself before the judgment-seat becomes guilty of his death. And such is also the case with him who does not avoid persecution, but out of daring presents himself for capture. Such a one, as far as in him lies, becomes an accomplice in the crime of the persecutor. And if he also uses provocation, he is wholly guilty, challenging the wild beast. Clement of Alexandria (A.D. 195) Ante-Nicene Fathers vol.2 pg.423

But why are you not helped when persecuted? say they. What wrong is done us, as far as we are concerned, in being released by death to go to the Lord, and so undergoing a change of life, as if a change from one time of life to another? Did we think rightly, we should feel obliged to those who have afforded the means for speedy departure, if it is for love that we bear witness; and if not, we should appear to the multitude to be base men. Clement of Alexandria (A.D. 195) Ante-Nicene Fathers vol.2 pg.423

When God gives to the tempter permission to persecute us, then we suffer persecution; and when God wishes us to be free from suffering, even in the midst of a world that hates us, we enjoy a wonderful peace, trusting in the protection of Him who said, "Be of good cheer, I have overcome the world." And truly He has overcome the world. Wherefore the world prevails only so long as it is the pleasure of Him who received from the Father power to overcome the world; and from His victory we take courage. Should He even wish us again to contend and struggle for our religion, let the enemy come against us, and we will say to them, "I can do all things, through Christ Jesus our Lord, which strengthens me." Origen (A.D. 248) Ante-Nicene Fathers vol.4 pg. 666
