sacrament necessarily becomes void in the case of the wicked, both must become void; if it remain valid with the wicked, this must be so with both. If, therefore, the baptism be acknowledged which he could not lose who severed himself from the unity of the Church, that baptism must also be acknowledged which was administered by one who by his secession had not lost the sacrament of conferring baptism. For as those who return to the Church, if they had been baptized before their secession, are not rebaptized, so those who return, having been ordained before their secession, are certainly not ordained again; but either they again exercise their former ministry, if the interests of the Church require it, or if they do not exercise it, at any rate they retain the sacrament of their ordination; and hence it is, that when hands are laid on them,[7] to mark their reconciliation, they are not ranked with the laity. For Felicianus, when he separated himself from them with Maximianus, was not held by the Donatists themselves to have lost either the sacrament of baptism or the sacrament of conferring baptism. For now he is a recognised member of their own body, in company with those very men whom he baptized while he was separated from them in the schism of Maximianus. And so others could receive from them, whilst they still had not joined our society, what they themselves had not lost by severance from our society. And hence it is clear that they are guilty of impiety who endeavour to rebaptize those who are in Catholic unity; and we act rightly who do not dare to repudiate God's sacraments, even when administered in schism. For in all points in which they think with us, they also are in communion with us, and only are severed from us in those points in which they dissent from us. For contact and disunion are not to be measured by different laws in the case of material or spiritual affinities. For as union of bodies arises from continuity of position, so in the agreement of wills there is a kind of contact between souls. If, therefore, a man who has severed himself from unity wishes to do anything different from that which had been impressed on him while in the state of unity, in this point he does sever himself, and is no longer a part of the united whole; but wherever he desires to conduct himself as is customary in the state of unity, in which he himself learned and received the lessons which he seeks to follow, in these points he remains a member, and is united to the corporate whole.
