But I need not repeat what I have already said of the Manicheans,—those arrogant and shallow philosophers who made such high pretension to superior wisdom; men who adored the divinity of mind, and the inherent evil of matter; men who sought to emancipate the soul, which in their view needed no regeneration from all the influences of the body. That this soul, purified by asceticism, might be reunited to the great spirit of the universe from which it had originally emanated, was the hopeless aim and dream of these theosophists,—not the control of passions and appetites, which God commands, but their eradication; not the worship of a Creator who made the heaven and the earth, but a vague worship of the creation itself. They little dreamed that it is not the body (neither good nor evil in itself) which is sinful, but the perverted mind and soul, the wicked imagination of the heart, out of which proceeds that which defileth a man, and which can only be controlled and purified by Divine assistance. Augustine showed that purity was an inward virtue, not the crucifixion of the body; that its passions and appetites are made to be subservient to reason and duty; that the law of temperance is self-restraint; that the soul was not an emanation or evolution from eternal light, but a distinct creation of Almighty God, which He has the power to destroy, as well as the body itself; that nothing in the universe can live without His pleasure; that His intervention is a logical sequence of His moral government. But his most withering denunciation of the Manicheans was directed against their pride of reason, against their darkened understanding, which led them not only to believe a lie, but to glory in it,—the utter perverseness of the mind when in rebellion to divine authority, in view of which it is almost vain to argue, since truth will neither be admitted nor accepted.
There was another class of Christians who provoked the controversial genius of Augustine, and these were the Donatists. These men were not heretics, but bigots. They made the rite of baptism to depend on the character of the officiating priest; and hence they insisted on rebaptism, if the priest who had baptized proved unworthy. They seemed to forget that no clergyman ever baptized from his own authority or worthiness, but only in the name of the Father, and the Son, and the Holy Ghost. Nobody knows who baptized Paul, and he felt under certain circumstances even that he was sent not to baptize, but to preach the gospel. Lay baptism has always been held valid. Hence, such reformers as Calvin and Knox did not deem it necessary to rebaptize those who had been converted from the Roman Catholic faith; and, if I do not mistake, even Roman Catholics do not insist on rebaptizing Protestants. But the Donatists so magnified, not the rite, but the form of it, that they lost the spirit of it, and became seceders, and created a mournful division in the Church,—a schism which gave rise to bitter animosities.
