18 But why should I recall instances from history and bring from books types of saintly women, when in your own city you have many before your eyes whose example you may well imitate? I shall not recount their merits here lest I should seem to flatter them. It will suffice to mention the saintly Marcella who, while she is true to the claims of her birth and station, has set before us a life which is worthy of the gospel. Anna “lived with an husband seven years from her virginity”; Marcella lived with one for seven months. Anna looked for the coming of Christ; Marcella holds fast the Lord whom Anna received in her arms. Anna sang His praise when He was still a wailing infant; Marcella proclaims His glory now that He has won His triumph. Anna spoke of Him to all those who waited for the redemption of Israel; Marcella cries out with the nations of the redeemed: “A brother redeems not, yet a man shall redeem,” and from another psalm: “A man was born in her, and the Highest Himself has established her.”
About two years ago, as I well remember, I published a book against Jovinian in which by the authority of scripture I crushed the objections raised on the other side on account of the apostle's concession of second marriages. It is unnecessary that I should repeat my arguments afresh here, as you can find them all in this treatise. That I may not exceed the limits of a letter, I will only give you this one last piece of advice. Think every day that you must die, and you will then never think of marrying again.
