It now becomes our duty to follow this changed system of education, which is indeed but a mixture of Christian and pagan, and hence not a separate and distinct system at all. It was designated by the apostle to the Gentiles as “the mystery of iniquity.” As found in the third century, Mosheim described it thus: “It is necessary, however, to observe that the methods now used of defending Christianity, and attacking Judaism and idolatry, degenerated much from the primitive simplicity, and the true rule of controversy. The _Christian doctors_, who had been _educated in the schools of the rhetoricians and sophists_, rashly employed the arts and evasions of their subtle masters in the service of Christianity; and, intent only upon defeating the enemy, they were too little attentive to the means of victory, indifferent whether they acquired it by artifice or plain dealing. This method of disputing, which the ancients called economical, and which _had victory for its object, rather than truth_, was, in consequence of the prevailing taste for rhetoric and sophistry, almost universally approved.”[68] The effect of the Christian schools’ teaching Greek literature, sophistry, and rhetoric was bearing its fruit in an unmistakable way. The simplicity of the gospel and of the man of God, who was the _truth_, was fast passing away. Even at this early date we find the germ of the order of Jesuits, who, in the Middle Ages, carried out the theory of the Platonists, and asserted “that it was no sin for a person to employ falsehood and fallacies for the support of truth, when it was in danger of being borne down.” It was at this time, and under the influence of these same doctors and teachers, that there arose the practice of attributing the writing of certain books to illustrious authors; “hence, the book of canons, which certain artful men ascribed falsely to the apostles, ... and many other productions of that nature, which, for a long time, were too much esteemed by credulous men.”[69] How far men had departed from the simplicity of the gospel is evident. [Sidenote: Error introduced by teachers] The spread of ideas contrary to the purity of the gospel was almost universally begun in the schools professing to be Christian; and teachers were, almost without exception, the leaders in these intellectual moves, which in reality form the basis for every change in government or religion. Throughout the history of the centuries, men have arisen who were noted for their intellectual prowess, men of strong mind, who were searching for truth. By tracing the work of a few representative teachers through the first three or four centuries, _we see the papacy appearing as the direct result of educational principles_.
