The Treatises of Cyprian

In Jeremiah: “Thus says the Lord, Walk not according to the way of the Gentiles.” Of this same thing, that one ought to separate himself from the Gentiles, lest he should be a companion of their sin, and become a partaker of their penalty, in the Apocalypse: “And I heard another voice from heaven, saying, Go forth from her, my people, lest you be partaker of her crimes, and lest you be stricken with her plagues; because her crimes have reached even to heaven, and the Lord God has remembered her iniquities.

Therefore He has returned unto her double, and in the cup which she has mixed double is mingled for her; and in how much she has glorified herself and possessed of delights, in so much is given unto her both torment and grief. For in her heart she says, I am a queen, and cannot be a widow, nor shall I see sorrow. Therefore in one hour her plagues shall come on her, death, grief, and famine; and she shall be burned with fire, because the Lord God is strong who shall judge her. And the kings of the earth shall weep and lament themselves for her, who have committed fornication with her, and have been conversant in her sins.” Also in Isaiah: “Go forth from the midst of them, you who bear the vessels of the Lord.”
