The passages the Scriptorium holds on screen, word for word from a public-domain translation. Written in Koine Greek.
“They dwell in their own countries, but only as sojourners… Every foreign country is a fatherland to them, and every fatherland is foreign. They marry like all other men and they beget children; but they do not cast away their offspring… Their existence is on earth, but their citizenship is in heaven. They love all men, and they are persecuted by all.”
Epistle to Diognetus 5.5–11 (trans. Lightfoot, public domain, lightly modernized).
“In a word, what the soul is in a body, this the Christians are in the world. The soul is spread through all the members of the body, and Christians through the divers cities of the world. The soul has its abode in the body, and yet it is not of the body; so Christians have their abode in the world, and yet they are not of the world.”
Epistle to Diognetus 6.1–3 (trans. Lightfoot, public domain, lightly modernized).
“The soul is enclosed in the body, and yet itself holds the body together; so Christians are kept in the world as in a prison-house, and yet they themselves hold the world together.”
Epistle to Diognetus 6.7 (trans. Lightfoot, public domain, lightly modernized).
“He sent him, as sending God; he sent him, as a man unto men; he sent him, as Saviour, as using persuasion, not force: for force is no attribute of God. He sent him, as summoning, not as persecuting; he sent him, as loving, not as judging.”
Epistle to Diognetus 7.4–5 (trans. Lightfoot, public domain, lightly modernized).
“He himself parted with his own Son as a ransom for us, the holy for the lawless, the guileless for the evil, the just for the unjust, the incorruptible for the corruptible, the immortal for the mortal. For what else but his righteousness would have covered our sins?”
Epistle to Diognetus 9.2–3 (trans. Lightfoot, public domain, lightly modernized).
“O the sweet exchange, O the inscrutable creation, O the unexpected benefits: that the iniquity of many should be concealed in One Righteous Man, and the righteousness of One should justify many that are iniquitous!”
Epistle to Diognetus 9.5 (trans. Lightfoot, public domain, lightly modernized).
Notes
Anonymous. The author calls himself only Mathetes — "a disciple." Written to an inquiring pagan of rank named Diognetus, whom nobody has ever identified. Dated anywhere from c. A.D. 130 to c. 220.
"O the sweet exchange" — ὢ τῆς γλυκείας ἀνταλλαγῆς. The sins of many hidden in one righteous man; the righteousness of one counted to many unrighteous. That is imputation, stated in the second or third century.
Not one ancient or medieval writer mentions this letter. It survived in a single manuscript at Strasbourg, which burned in the bombardment of 1870. Every copy since rests on transcriptions made before the fire.
