The choice of a layman by the emperor shows that an ecclesiastic at that time had not the qualities indispensable for a task so delicate. In fact, St. Augustine remarks that a bishop of Bresse, called Philastrius, whose work is to be found in the collection of the fathers, having collected all the heresies, even including those which existed among the Jews before the coming of Jesus Christ, reckons twenty-eight of the latter and one hundred and twenty-eight from the coming of Christ; while St. Epiphanius, comprising both together, makes the whole number but eighty. The reason assigned by St. Augustine for this difference is, that what appears heresy to the one, does not appear so to the other. Accordingly this father tells the Manichæans: "We take the greatest care not to treat you with rigor; such conduct we leave to those who know not what pains are necessary for the discovery of truth, and how difficult it is to avoid falling into errors; we leave it to those who know not with what sighs and groans even a very slight knowledge of the divine nature is alone to be acquired. For my own part, I consider it my duty to bear with you as I was borne with formerly myself, and to show you the same tolerance which I experienced when I was in error." If, however, any one considers the infamous imputations, which we have noticed under the article on "Genealogy," and the abominations of which this professedly indulgent and candid father accused the Manichæans in the celebration of their mysteries--as we shall see under the article on "Zeal"--we shall be convinced that toleration was never the virtue of the clergy. We have already seen, under the article on "Council," what seditions were excited by the ecclesiastics in relation to Arianism. Eusebius informs us that in some places the statues of Constantine were thrown down because he wished the Arians to be tolerated; and Sozomen says that on the death of Eusebius of Nicomedia, when Macedonius, an Arian, contested the see of Constantinople with Paul, a Catholic, the disturbance and confusion became so dreadful in the church, from which each endeavored to expel the other, that the soldiers, thinking the people in a state of insurrection, actually charged upon them; a fierce and sanguinary conflict ensued, and more than three thousand persons were slain or suffocated. Macedonius ascended the episcopal throne, took speedy possession of all the churches, and persecuted with great cruelty the Novatians and Catholics. It was in revenge against the latter of these that he denied the divinity of the Holy Spirit, just as he recognized the divinity of the Word, which was denied by the Arians out of mere defiance to their protector Constantius, who had deposed him.
