6. But as the Church was to last to the end of time, something more was required besides the bestowal of the Sacred Scriptures. It was obviously necessary that the Divine Founder should take every precaution, lest the treasure of heavenly-given truths, possessed by the Church, should ever be destroyed, which would assuredly have happened, had He left those doctrines to each one's private judgment. It stands to reason, therefore, that a living, perpetual "magisterium" was necessary in the Church from the beginning, which, by the command of Christ himself, should besides teaching other wholesome doctrines, give an authoritative explanation of Holy Writ, and which being directed and safeguarded by Christ himself, could by no means commit itself to erroneous teaching. God has provided for these needs most wisely and effectively through His Only-begotten Son Jesus Christ, Who placed the true sense of the Scriptures in safety, when He laid upon His Apostles as His primary and most momentous injunction, not to devote themselves to writing, nor to spreading the volumes of the Old Testament indiscriminately and unguardedly among the multitude, but to teach all nations with the living voice, and to lead them by speech to the knowledge and profession of His Heavenly doctrine: "Going into the whole world preach the Gospel to every creature." (Mark xvi. 15.) But the supreme teaching authority was committed to one, on whom, as on its foundation, the Church must rest. For Christ when He gave the keys to Peter, gave him at the same time the power to govern those who were charged with the "ministry of the word:" "Confirm thy Brethren" (Luke xxii. 32). And since the faithful must learn from the "magisterium" of the Church whatever pertains to the salvation of their souls, it follows that they must also learn from it the true meaning of Scripture.
