Chap. ii.—2. Nevertheless, I see what may still be required of me, viz. that I should answer those plausible arguments, by which, in even earlier times, Agrippinus, or Cyprian himself, or those in Africa who agreed with them, or any others in far distant lands beyond the sea, were moved, not indeed by the authority of any general or even provincial Council, but by a mere epistolary correspondence, to think that they ought to adopt a custom which had no sanction from the ancient custom of the Church, and which was expressly forbidden by the most unanimous resolution of the Catholic world, in order that an error which had begun to creep into the minds of some men, through discussions of this kind, might be cured by the more powerful truth and universal healing power of unity coming on the side of safety. And so they may see with what security I approach this discourse. If I am unable to gain my point, and show how those arguments may be refuted which they bring forward from the Council and the epistles of Cyprian, to the effect that Christ's baptism may not be given by the hands of heretics, I shall still remain safely in the Church, in whose communion Cyprian himself remained with those who differed from him.
