Chapter 20.
22. Wherefore all this about the generation of vipers, and the poison of asps under their lips, and all the other things which they have said against those which have not known the way of peace, are really, if they would but speak the truth, more strictly applicable to themselves, since for the sake of the peace of Donatus they received the baptism of these men, in respect of which they used the expressions quoted above in the wording of the decree of the Council; but the baptism of the Church of Christ dispersed throughout the world, from which peace itself came into Africa, they repudiate, to the sacrilegious wounding of the peace of Christ. Which, therefore, are rather the false prophets, who come in sheep's clothing, while inwardly they are ravening wolves, -they who either fail to detect the wicked in the Catholic Church, and communicate with them in all innocence, or else for the sake of the peace of unity are bearing with those whom they cannot separate from the threshing-floor of the Lord before the Winnower shall come, or they who do in schism what they censure in the Catholic Church, and receive in their own separation, when manifest to all and condemned by their own voice, what they profess that they shun in the unity of the Church when it calls for toleration, and does not even certainly exist?
Chap. 21.-23. Lastly, it has been said, as he himself has also quoted, "Ye shall know them by their fruits:" let us therefore examine into their fruits. You bring up against our predecessors their delivery of the sacred books. This very charge we urge with greater probability against their accusers themselves. And not to carry our search too far, in the same city of Constantina your predecessors ordained Silvanus bishop at the very outset of his schism. He, while he was still a subdeacon, was most unmistakeably entered as a traditor in the archives of the city. If you on your side bring forward documents against our predecessors, all that we ask is equal terms, that we should either believe both to be true or both to be false. If both are true, you are unquestionably guilty of schism, who have pretended that you avoid offenses in the communion of the whole world, which you had commonly among you in the small fragment of your own sect. But again, if both are false, you are unquestionably guilty of schism, who, on account of the false charges of giving up the sacred books, are staining yourselves with the heinous offence of severance from the Church. But if we have something to urge in accusation while you have nothing, or if our charges are true whilst yours are false, it is no longer matter of discussion how thoroughly your mouths are closed.
