Chap. x.—13. Therefore Cyprian writes to Jubaianus as follows, "concerning the baptism of heretics, who, being placed without, and set down out of the Church," seem to him to "claim to themselves a matter over which they have neither right nor power. Which we," he says, "cannot account valid or lawful, since it is clear that among them it is unlawful." Neither, indeed, do we deny that a man who is baptized among heretics, or in any schism outside the Church, derives no profit from it so far as he is partner in the perverseness of the heretics and schismatics; nor do we hold that those who baptize, although they confer the real true sacrament of baptism, are yet acting rightly, in gathering adherents outside the Church, and entertaining opinions contrary to the Church. But it is one thing to be without a sacrament, another thing to be in possession of it wrongly, and to usurp it unlawfully. Therefore they do not cease to be sacraments of Christ and the Church, merely because they are unlawfully used, not only by heretics, but by all kinds of wicked and impious persons. These, indeed, ought to be corrected and punished, but the sacraments should be acknowledged and revered.
