Note 94 — Chapter IV · THE SPREAD OF ISLAM AMONG THE CHRISTIAN NATIONS OF AFRICA.

In 646, the year before the victorious Arabs advanced from Egypt to the subjugation of the western province, the African Church that had championed so often the purity of Christian doctrine, was stirred to its depths by the struggle against Monotheletism; but when the bishops of the four ecclesiastical provinces in the archbishopric of Carthage, viz. Mauritania, Numidia, Byzacena and Africa Proconsularis, held councils to condemn Monotheletism, and wrote synodal letters to the Emperor and the Pope, there were only sixty-eight bishops who assembled at Carthage to represent the last-mentioned province, and forty-two for Byzacena. The numbers from the other two dioceses are not given, but the Christian population had undoubtedly suffered much more in these than in the two other dioceses which were nearer to the seat of government.94 It is exceedingly unlikely that any of the bishops were absent on an occasion that excited so much feeling, when zeal for Christian doctrine and political animosity to the Byzantine court both combined in stimulating this movement, and when Africa took the most prominent part in stirring up the opposition that led to the convening of the great Lateran Council of 648. This diminution in the number of the African bishops certainly points to a vast decrease in the Christian population, and in consideration of the numerous causes contributing to a decay of the population, too great stress even must not be laid upon the number of these, because an episcopal see may continue to be filled long after the diocese has sunk into insignificance.
