Compare Cyprian’s epistle to Quintus concerning the baptism of heretics (Ep. 70, al. 71). Cyprian there takes the position stated here, that those who have been baptized in the Church and have afterward gone over to heresy and then returned again to the Church are not to be re-baptized, but to be received with the laying on of hands only. This of course does not at all invalidate the position of Cyprian and the others who re-baptized heretics, for they baptized heretics not because they had been heretics, but because they had not received true baptism, nor indeed any baptism at all, which it was impossible, in their view, for a heretic to give. They therefore repudiated (as Cyprian does in the epistle referred to) the term re-baptism, denying that they re-baptized anybody.
