CHAPTER XIV — THE DEMONS MISREPRESENT CHRISTIAN DOCTRINE
We who hated and destroyed one another, and on account of their different manners would not live with men of a different tribe, now, since the coming of Christ, live familiarly with them, and pray for our enemies, and endeavour to persuade those who hate us unjustly to live comformably to the good precepts of Christ, to the end that they may become par-takers with us of the same joyful hope of a reward from God the ruler of all.
CHAPTER XVI — CONCERNING PATIENCE AND SWEARING
And concerning our being patient of injuries, and ready to serve all, and free from anger, this is what He said: “To him that smiteth thee on the one cheek, offer also the other; and him that taketh away thy cloak or coat, forbid not. And whosoever shall be angry, is in danger of the fire. And every one that compelleth thee to go with him a mile, follow him two. And let your good works shine before men, that they, seeing them, may glorify your Father which is in heaven.” For we ought not to strive; neither has He desired us to be imitators of wicked men, but He has exhorted us to lead all men, by patience and gentleness, from shame and the love of evil. And this indeed is proved in the case of many who once were of your way of thinking, but have changed their violent and tyrannical disposition, being overcome either by the constancy which they have witnessed in their neighbours’ lives, or by the extraordinary forbearance they have observed in their fellow-travellers when defrauded, or by the honesty of those with whom they have transacted business.
CHAPTER XVII — CHRIST TAUGHT CIVIL OBEDIENCE
And everywhere we, more readily than all men, endeavour to pay to those appointed by you the taxes both ordinary and extraordinary, as we have been taught by Him; for at that time some came to Him and asked Him, if one ought to pay tribute to Caesar; and He answered, “Tell Me, whose image does the coin bear?” And they said, “Caesar’s.” And again He answered them, “Render therefore to Caesar the things that are Caesar’s, and to God the things that are God’s.” Whence to God alone we render worship, but in other things we gladly serve you, acknowledging you as kings and rulers of men, and praying that with your kingly power you be found to possess also sound judgment. But if you pay no regard to our prayers and frank explanations, we shall suffer no loss, since we believe (or rather, indeed, are persuaded) that every man will suffer punishment in eternal fire according to the merit of his deed, and will render account according to the power he has received from God, as Christ intimated when He said, “To whom God has given more, of him shall more be required.”
CHAPTER XXXIX — DIRECT PREDICTIONS BY THE SPIRIT
And when the Spirit of prophecy speaks as predicting things that are to come to pass, He speaks in this way: “For out of Zion shall go forth the law, and the word of the Lord from Jerusalem. And He shall judge among the nations, and shall rebuke many people; and they shall beat their swords into ploughshares, and their spears into pruning-hooks: nation shall not lift up sword against nation, neither shall they learn war any more.” And that it did so come to pass, we can convince you. For from Jerusalem there went out into the world, men, twelve in number, and these illiterate, of no ability in speaking: but by the power of God they proclaimed to every race of men that they were sent by Christ to teach to all the word of God; and we who formerly used to murder one another do not only now refrain from making war upon our enemies, but also, that we may not lie nor deceive our examiners, willingly die confessing Christ.
