Before finally quitting the earth Our Lord founded His Church, a hierarchical society of men, to continue the work which He had begun for the sanctification and salvation of the whole human race. His last solemn commission to His apostles was a command to teach men to observe all that He had commanded; certain truths had been revealed to them concerning God, as well as moral rules for their guidance, but even the truths concerning God were not merely speculative; they, too, were revealed for the sanctificat,ion and salvation of men. A duty of submission of the intellect, under pain of eternal damnation, was laid on all who heard the Gospel preached. The basis of Christian morality thus rests firmly established on the word of God, requiring unwavering faith, not on the uncertain and shifting sands of human opinion. That Gospel contained not only moral precepts which are obligatory on all, but counsels also of great perfection which those who had the moral strength were encouraged to adopt as rules for the conduct of their lives. The perfect holiness of God Himself was held up as the model which they were to imitate and the lofty ideal at which they were ever to aim.
