ST. JEROME " [Helvidius] produces Tertullian as a witness to (his view) and quotes Victorinus, bishop of Petavium. Of Tertullian, I say no more than that he did not belong to the Church . But as regards Victorinus, I assert what has already been proven from the gospel—that he (Victorinus) spoke of the brethren of the Lord not as being sons of Mary but brethren in the sense I have explained, that is to say, brethren in point of kinship, not by nature. By discussing such things (we) are . . . following the tiny streams of opinion. Might I not array against you the whole series of ancient writers? Ignatius, Polycarp, Irenaeus, Justin Martyr, and many other apostolic and eloquent men, who against (the heretics) Ebion, Theodotus of Byzantium, and Valentinus, held these same views and wrote volumes replete with wisdom. If you had ever read what they wrote, you would be a wiser man "—St. Jerome Against Helvidius: The Perpetual Virginity of Mary 19, [A.D. 383]
