In the course of centuries, the primitive simplicity of the Gospel and the purity of life which distinguished the first Christians had been lost in the complex theology, in the unseemly contests for precedence, in the crimes and the licentiousness which distracted the society of the Eternal City. From a simple priest, whose tenure of office was dependent on the pleasure of his associates, the Bishop of Rome had been exalted into a mighty sovereign, responsible only to the powers of Heaven. The palace of the Vatican exhibited all the vices of the most corrupt of courts. The assumption of infallibility,--an inevitable result of the preposterous claims of the Papacy,--through the contradictory interpretations of different individuals whose interests were conflicting led to the most opposite conclusions, often to results fatal to the peace and honor of the Church. The faith of the populace was weakened. Infidelity in the priesthood became too common to excite remark. The universal depravity was incredible and appalling. The general demoralization resulting from the example of the clergy, whose atheism and debauchery were proverbial, threatened the existence of society, a catastrophe which the thorough organization of the hierarchy alone prevented. Even in the fifteenth century Machiavelli wrote, “The nearer a nation is to Rome the more impious are the people.” When the German Schopp called the famous scholar, Casaubon, an atheist, the latter retorted: “If I were an atheist I should now be at Rome, where I have often been invited.” The effects of this superb ecclesiastical organization were not long in manifesting themselves. The legitimate resources of power were aided by every device of fraud, of oppression, of imposture, of forgery. A succession of able and unprincipled pontiffs fastened on Christendom a yoke which the intelligence and the science of subsequent generations have not even yet been able to entirely remove. The temporal supremacy of the Cæsars was re-established over Europe; the dogmas of Catholicism were preached in distant continents unknown to the ancient world; and a tyranny far more terrible in its consequences than that experienced under the cruel rule of Nero and Domitian was imposed upon the intellectual aspirations of mankind.
