Book III

Augustin contends that the Donatists by their schism from especially the Eastern churches had violated the principle of toleration, which their boasted leader had so strenuously enforced. There follows then a seriatim consideration of the points made by Cresconius, similar to those maintained by Petilian, as to the importance of the origin and the head and root in baptism, or the character of the celebrant, and the rebaptism by Paul of John's disciples. The case of Optatus and the Maximianists next come under review, as witnesses against their testimonies. Cresconius says he will neither absolve nor condemn Optatus, and as to the Maximianists, he professes to have made special inquiry into the whole history. The Synod had granted a season of delay during which all who returned should be held innocent. Of this very many availed themselves; the baptism of these was valid; those who remained outside lost both baptism and the church. Augustin refutes the statement from its inherent contradictions and from the language of the Synod against the Maximianists. Cresconius also brings forward the Sardican council's letter to Donatus as a proof of sustained fellowship. Augustin declares it to be an Arian council; and he insists on paralleling all Cresconius would say about Cæcilianism with the career of the Maximianists. With reference to persecution, he cites in extenso their own persecutions, the case of Severus, bishop of Thubursicubur; the acts of Optatus; his own treatment at a collation by the Circumcelliones; the case of Crispinus, the Donatist bishop of Calama; their own invocation of the state against the Maximianists. Thence he returns to the doctrine of the unity as universal with many of the familiar Scripture texts, and asserts by the documents that the Donatists were the occasion of the rupture.
