22 How great inconveniences are involved in wedlock and how many anxieties encompass it I have, I think, described shortly in my treatise— published against Helvidius — on the perpetual virginity of the blessed Mary. It would be tedious to go over the same ground now; and any one who pleases may draw from that fountain. But lest I should seem wholly to have passed over the matter, I will just say now that the apostle bids us pray without ceasing, and that he who in the married state renders his wife her due cannot so pray.
Either we pray always and are virgins, or we cease to pray that we may fulfil the claims of marriage. Still he says: “If a virgin marry she has not sinned. Nevertheless such shall have trouble in the flesh.” At the outset I promised that I should say little or nothing of the embarrassments of wedlock, and now I give you notice to the same effect. If you want to know from how many vexations a virgin is free and by how many a wife is fettered you should read Tertullian “to a philosophic friend,” and his other treatises on virginity, the blessed Cyprian's noble volume, the writings of Pope Damasus in prose and verse, and the treatises recently written for his sister by our own Ambrose. In these he has poured forth his soul with such a flood of eloquence that he has sought out, set forth, and put in order all that bears on the praise of virgins.
