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.
