and died suddenly, under very suspicious circumstances, in A.D. 336. Throughout this century the struggle proceeded furiously, each party in turn getting the upper hand, as the emperor of the time inclined towards Catholicism or towards Arianism, and each persecuting the adherents of the other. Among Arian subdivisions we find Semi-Arians, Eusebians, Aetians, Eunomians, Acasians, Psathyrians, etc. Then we have the Apollinarians, who maintained that Christ had no human soul, the divinity supplying its place; the Marcellians, who taught that a divine emanation descended on Christ. Allied to the Manichæan heresy were the Priscillians, the Saccophori, the Solitaries, and many others; and, in addition, the Messalians or Euchites, the Luciferians, the Origenists, the Antidicomarianites, and the Collyridians. A quarrel about the consecration of a bishop gave rise to fierce struggles not connected with the doctrine, so much as with the discipline of the Church. The Bishops of Numidia were angered by not having been called to the consecration of Cæcilianus Bishop of Carthage, and, assembling together, they elected and consecrated a rival bishop to that see, and declared Cæcilianus incompetent for the episcopal office. Donatus, Bishop of Casa Nigra, was the foremost of these Numidian malcontents, and from him the sect of Donatists took its name; they denied the orders of those ordained by Cæcilianus, and hence the validity of the Sacraments administered by them. Excommunicated themselves, "they boldly excommunicated the rest of mankind who had embraced the impious party of Cæcilianus, and of the traditors, from whom he derived his pretended ordination. They asserted with confidence, and almost with exultation, that the apostolical succession was interrupted, that _all_ the bishops of Europe and Asia were infected by the contagion of guilt and schism, and that the prerogatives of the Catholic Church were confined to the chosen portion of the African believers, who alone had preserved inviolate the integrity of their faith and discipline. This rigid theory was supported by the most uncharitable conduct. Whenever they acquired a proselyte, even from the distant provinces of the east, they carefully repeated the sacred rites of baptism and ordination; as they rejected the validity of those which he had already received from the hands of heretics or of schismatics" (Gibbon's "Decline and Fall," vol. iii. pp. 5, 6). A number of Donatists, known as Circumcelliones, "maintained their cause by the force of arms, and overrunning all Africa, filled that province with slaughter and rapine, and committed the most enormous acts of perfidy and cruelty against the followers of Caecilianus" (p. 109). To complete the darkly terrible picture of the Church in the fourth century, we need only note the various orders of fanatical monks, filthy in their habits, densely ignorant, hopelessly superstitious, amongst whom may be numbered the travelling mendicants called Sarabaites.
