Tertullian, On Exhortation to Chastity 11
There's a double shame in it: in a second marriage two wives close in on the same husband — one in spirit, the other in flesh. You cannot hate the first, not when you reserve a more religious affection for her, now that she's been received by the Lord; you pray for her spirit, you make annual offerings for her. So will you stand before the Lord with as many wives as you name in prayer? Will you offer for two? Will you commend those two through a priest ordained from monogamy, or even consecrated from virginity, surrounded by virgins and men of one wife, and will your sacrifice go up with a free forehead? And among the other desires of a good mind, will you ask for chastity for yourself and your wife?
Latin
Duplex enim rubor est; quia in secundo matrimonio duae uxores eumdem circumstant maritum; una spiritu, alia in carne: neque enim pristinam poteris odisse, cui etiam religiosiorem reservas affectionem, ut jam receptae apud Dominum, pro cujus spiritu postulas, pro qua oblationes annuas reddis. Stabis ergo ad Dominum cum tot uxoribus, quot in oratione commemoras? et offeres pro duabus? et commendabis illas duas per sacerdotem de monogamia ordinatum, aut etiam de virginitate sancitum, circumdatum virginibus ac univiris, et ascendet sacrificium tuum libera fronte? et inter caeteras voluntates bonae mentis, postulabis tibi et uxori castitatem?
