Origen on Christians Living in Lawless Cultures Around 250CE

Tell us whether the laws of the Scythians, which permit the murder of parents, are right laws; or those of the Persians, which do not forbid the marriages of sons with their mothers, or of daughters with their own fathers. But what need is there for me to make selections from those who have been engaged in the business of enacting laws among the different nations, and to inquire how the laws are rightly enacted among each, according as they please the superintending powers? …

Tell us how it would be an act of impiety to get rid of those ancestral laws which permit the marriages of mothers and daughters; or which pronounce a man happy who puts an end to his life by hanging, or declare that they undergo entire purification who deliver themselves over to the fire, and who terminate their existence by fire; and how it is an act of impiety to do away with those laws which, for example, prevail in the Tauric Chersonese, regarding the offering up of strangers in sacrifice to Diana, or among certain of the Libyan tribes regarding the sacrifice of children to Saturn. …

Each one of us, then, is come “in the last days,” when one Jesus has visited us, to the “visible mountain of the Lord,” the Word that is above every word, and to the “house of God,” which is “the Church of the living God, the pillar and ground of the truth.” … And this house is exalted above the hills, i.e., those individuals among men who make a profession of superior attainments in wisdom and truth; and all the nations come to it, and the “many nations” go forth, and say to one another, turning to the religion which in the last days has shone forth through Jesus Christ: “Come ye, and let us go up to the mountain of the LORD, to the house of the God of Jacob; and He will teach us of His ways, and we will walk in them.”…

Moreover, the word of the Lord came forth from that very Jerusalem, that it might be disseminated through all places, and might judge in the midst of the heathen, selecting those whom it sees to be submissive, and rejecting the disobedient, who are many in number. And to those who inquire of us from where we come, or who is our founder, we reply that we have come agreeably to the counsels of Jesus to “cut down our hostile and insolent ‘wordy’ swords into ploughshares, and to convert into pruning-hooks the spears formerly employed in war.” For we no longer take up “sword against nation,” nor do we “learn war any more,” having become children of peace, for the sake of Jesus, who is our leader, instead of those whom our fathers followed, among whom we were “strangers to the covenant,” and having received a law, for which we give thanks to Him that rescued us from the error of our ways.

Shepherd of Hermas on Marriage and Adultery in 150CE

“I charge you,” he said, “to guard your chastity, and let no thought enter your heart of another man’s wife, or of fornication, or of similar iniquities; for by doing this you commit a great sin. But if you always remember your own wife, you will never sin. For if this thought enters your heart, then you will sin; and if, in like manner, you think other wicked thoughts, you commit sin. For this thought is a great sin in a servant of God. But if any one commits this wicked deed, he works death for himself. Attend, therefore, and refrain from this thought; for where purity dwells, there iniquity ought not to enter the heart of a righteous man.”

I said to him, “Sir, permit me to ask you a few questions.” “Go on,” he said. And I said to him, “Sir, if any one has a wife who trusts in the Lord, and if he detects adultery in her, does the man sin if he continues to live with her?” And he said to me, “As long as he remains ignorant of her sin, the husband commits no transgression in living with her. But if the husband knows that his wife has gone astray, and if the woman does not repent, but persists in her fornication, and yet the husband continues to live with her, he also is guilty of her crime, and a sharer in her adultery.”

And I said to him, “What then, sir, is the husband to do, if his wife continues in her vicious practices?” And he said, “The husband should put her away, and remain by himself. But if he puts his wife away and marries another, he also commits adultery.” And I said to him, “What if the woman put away should repent, and wish to return to her husband: shall she not be taken back by her husband?” And he said to me, “Assuredly. If the husband does not take her back, he sins, and brings a great sin upon himself; for he ought to take back the sinner who has repented. But not frequently. For there is but one repentance to the servants of God.

In case, therefore, that the divorced wife may repent, the husband ought not to marry another, when his wife has been put away. In this matter man and woman are to be treated exactly in the same way. Moreover, adultery is committed not only by those who pollute their flesh, but by those who imitate the heathen in their actions. Therefore if any one persists in such deeds, and does not repent, withdraw from him, and cease to live with him, otherwise you are a sharer in his sin.

Therefore the injunction has been laid on you, that you should remain by yourselves, both man and woman, for in such persons repentance can take place. But I do not,” said he, “give opportunity for the doing of these deeds, but that he who has sinned may sin no more. But with regard to his previous transgressions, there is One who is able to provide a cure; for it is He, indeed, who has power over all.”
