"The schisms and commotions that arose in the church, from a mixture of the oriental and Egyptian philosophy with the Christian religion were, in the second century, increased by those Grecian philosophers who embraced the doctrine of Christ. The Christian doctrine, concerning the Father, Son, and Holy Ghost, and the two natures united in our blessed Savior, were by no means reconcilable with the tenets of the sages and doctors of Greece, who therefore endeavored to explain them in such a manner as to render them comprehensible. Praxeas, a man of genius and learning, began to propagate these explications at Rome, and was severely persecuted for the errors they contained. He denied any real distinction between the Father, Son, and Holy Ghost; and maintained that the Father, sole Creator of all things, had united to Himself the human nature of Christ. Hence his followers were called Monarchians, because of their denying a plurality of persons in the Deity; and also Patropassians, because, according to Tertullian's account, they believed that the Father was so intimately united with the man Christ, His Son, that He suffered with Him the anguish of an afflicted life and the torments of an ignominious death. However ready many may have been to embrace this erroneous doctrine, it does not appear that this sect formed to themselves a separate place of worship, or removed themselves from the ordinary assemblies of Christians."--(Mosheim, "Ecclesiastical History," Cent. II, Part II, ch. 5:20.) 5. _Spurious Writings in the Apostolic Period_. "Not long after Christ's ascension into heaven, several histories of His life and doctrines, full of pious frauds and fabulous wonders, were composed by persons whose intentions, perhaps, were not bad, but whose writings discovered the greatest superstition and ignorance. Nor was this all: productions appeared which were imposed upon the world by fraudulent men, as the writings of the holy apostles. These apocryphal and spurious writings must have produced a sad confusion, and rendered both the history and the doctrine of Christ uncertain, had not the rulers of the church used all possible care and diligence in separating the books that were truly apostolical and divine from all that spurious trash."--(Mosheim, "Ecclesiastical History," Cent. I, Part II, ch. 2:17.) CHAPTER VIII. **Internal Causes.--Continued**. 1. As one of the effective causes leading to the apostasy of the Primitive Church we have specified: _Unauthorized additions to the ceremonies of the Church, and the introduction of vital changes in essential ordinances_.
