Towards the close of the century, this schism attracted the attention of Augustine, then a priest of Hippo Regius in Numidia. The controversy seems to have had for him a special attraction, not merely because of its intrinsic importance, but also because of the field which it presented for his unrivalled powers as a dialectician. These the Donatists had recently provoked, by inconsistently receiving back into their body a deacon of Carthage named Maximianus who had separated himself from them, and by recognising as valid all baptism administered by his followers. Hence they naturally shrank from engaging in a contest with an antagonist who was sure to make the most of such a deviation from the very principles on which they based their schism; and, on the other hand, Augustine was so firmly convinced that his own position was impregnable, that he seems to have thought that if he could only secure a thorough and dispassionate discussion of the matter, the Donatists must necessarily be brought to acknowledge not only their theoretical errors, but also the practical sinfulness of their separation from the Church. Throughout the controversy, however, he appears to have put out of sight two considerations: first, the influence of party spirit and prejudice in blinding men to argument; and, secondly, the necessity of treating his opponents in a logical discussion as on an equal footing with himself. The first was in some degree an unavoidable element of disappointment; but Augustine made concession yet more difficult on the part of his opponents, by expecting them to acknowledge his superior position as a member of the Catholic Church, whose duty it was to expose the error of their views. He practically begs the very point at issue, by assuming that he, and not the Donatists, was in the Catholic communion; and though his argument is conducted independently of this premiss, yet it naturally rendered them more unwilling to admit its force. This dogmatism was of less consequence in the first pamphlet which Augustine published on the subject,--his _Alphabetical Psalm_, in which he set forth the history and errors of the Donatists in a popular form,--since it was not intended as a controversial treatise, but only as a means of enlightening the less educated as to the Catholic tenets on the question in dispute. His next work, written in answer to a letter of Donatus of Carthage, in which the latter tried to prove that the baptism of Christ existed only in his communion, is unfortunately lost; and we can only gather hints as to the further part which he took in the controversy during the next few years from certain of his letters, especially those to the Donatist Bishops Honoratus and Crispinus.[2] From the former he claims the admission that the exclusiveness of the Donatists proves that they are not the Church of Christ; and his letter to the latter contains an invitation to discuss the leading points at issue, which Crispinus seems to have declined.
