Church practices like not rebaptizing may be held without binding as heresy — Cyprian
So we can answer adversaries who attack the sufficiency we give Scripture. They object that our churches hold and teach some things not drawn from Scripture by consequences open and necessary enough to bind the people's faith unless some other divine authority props them up — for example, that those once baptized among heretics are not to be baptized again.
That teaching, and some others, our churches do hold and teach as agreeing with Scripture, and as confirmed by long use and the common vote of the faithful. It is rash to condemn and reject them.
Yet we do not give them such necessity that they bind Christian faith as such — as if whoever thinks otherwise must be struck from the faithful and counted a heretic. We would never want Cyprian so numbered: a holy man and martyr of Christ, who did not hold the same view of heretics' baptism that our churches hold.
Latin
XXIV. Inde vero colligi potest quid sit respondendum adversariis, dum impugnantes sufficientiam, quam Scripturae sacrae tribuimus, objiciunt quaedam in nostris Ecclesiis teneri, & doceri, quae tamen per consequentias tam apertas & necessarias ex Scriptura non deducuntur, ut possint Christiani populi fidem obligare, nisi aliunde divina quadam authoritate fulciantur: ut ex. gr. non esse de novo baptizandos eos qui semel apud haereticos baptismum susceperunt. Etenim dogma istud, & alia nonnulla in Ecclesiis nostris tenentur quidem, & docentur, ut Scripturae consentanea, & praeterea longo usu & communi fidelium suffragio probata, quae propterea temerarium est damnare atque rejicere: nec tamen eam illis tribuimus necessitatem, ut Christianorum fidem necessario obligent, adeo ut qui aliter sentit sit e fidelium numero expungendus, & accensendus haereticis, quibus minime vellemus annumeratum Cyprianum virum sanctum & Christi martyrem, qui de baptismo haereticorum non idem sensit quod Ecclesiae nostrae.
