Donatus and Donatism. The Donatists were the first Christians who
separated from the church on the ground of discipline, though the church had already been torn by heresies, such as Gnosticism and Manicheism, which had affected doctrines. It is important to remember that Donatism was not heresy, as the word is ordinarily understood. All heretics are, in one sense, schismatics, but all schismatics are not heretics; and the Donatists themselves protested, with justice, against being considered heretics.
Mensurius was bp. of Carthage during and after Diocletian's persecution (
303). Having been required by consul Anulinus to give up any copies of Holy Scripture in his possession, he had hid them, and passed off

heretical works
in their stead. The consul, learning the "pious fraud," declined to take further
action. Mensurius felt it his duty to check the growing and inordinate reverence
for martyrdom. He saw that there were too many would-be martyrs whose character
would not bear close scrutiny, and, together with his archdeacon Caecilian, did
his best to discountenance the reverence of good but mistaken Christians for these undeserving men. This naturally brought him into odium with those to whom martyrdom was the becoming conclusion of the Christian life.

During his lifetime the storm was brewing, and it fairly broke out when Caecilian succeeded him ( 311). That appointment was felt to be a blow to all who magnified martyrdom. His opponents rested their principal objection on the fact that he had been ordained by a traditor, Felix of Aptunga; and proceeded to elect Majorinus as successor to Mensurius. The charge was a strange one to be made by Caecilian's chief opponent, , bp. of Tigisis, for documents exist which prove Secundus himself a traditor, in spite of his boast to Mensurius. From that date Donatism, as it was afterwards called, had a separate and schismatical existence. Both sides appealed to Constantine, and the emperor at once subjected the alleged traditorship of Felix to a thorough examination by a council at Rome ( 313), which decided in favour of Felix, cleared his character, and consequently declared the ordination of Caecilian valid. The subject was again exhaustively discussed before the consul Aelianus, who, at the bidding of Constantine, gave the Donatists another opportunity ( 314), at Carthage, of proving their charge against Felix. The finding of the tribunal was unanimous: "Nemo in eum (Felicem) aliquid probare potuerit quod religiosissimas scripturas tradiderit vel exusserit."

Bp. Majorinus died 315, but
had been a leader of little consequence. His followers had called themselves, for convenience' sake, the party of Majorinus; but after his death, if not before, they took the name—Donatists—by which they are best known. There were perhaps 2 bishops named Donatus; (1) of Casae Nigrae, who, before Caecilian's elevation, had shewn his schismatical tendencies; (2) the successor of Majorinus and surnamed "the Great." But this distinction has lately been questioned; see Sparrow Simpson, St. Aug. and Afr. Ch. Divisions (1910), p. 31; Monceaux, Revue de l’Hist. de Religion (1909).
