The Bible had produced the Reformer and begun the Reformation. Luther, in believing, had no need of the testimony of the Church. His faith was derived from the Bible itself; from within, and not from without. His thorough conviction that the evangelical doctrine was immovably founded on the word of God made him regard all external authority as useless. Luther's experience, in this respect, opened a new prospect to the Church. The living spring which had burst forth before the monk of Wittemberg, was destined to become a stream at which nations would quench their thirst. The Church had said that, in order to understand the Word, the Spirit of God must interpret it, and so far the Church was right. But her error consisted in regarding the Holy Spirit as a monopoly conferred on a certain caste, and in thinking that it could be appropriated exclusively to certain assemblies and colleges, to a city or a conclave. "The wind bloweth where it listeth," were the words of the Son of God, when speaking of the Spirit of God; and, on another occasion, "They will ALL be taught of God." The corruption of the Church, the ambition of pontiffs, the animosities of councils, the squabbles of the clergy, and the pomp of prelates, had made this Holy Spirit, this breath of humility and peace, eschew the dwelling of the priesthood. He had deserted the assemblies of the proud, and the palaces of the princes of the Church, and gone to live in retirement among simple Christians and modest priests. He had shunned a domineering hierarchy, which often forced blood from the poor, whom it trampled under foot; he had shunned a proud and ignorant clergy, whose chiefs were skilled, not in the Bible, but in the sword; and he was found sometimes among despised sects, and sometimes among men of talents and learning. The holy cloud, withdrawing from proud basilisks and gorgeous cathedrals, had descended on the obscure dwellings of the humble, or on chambers where studious men calmly pursued their conscientious labours. The Church, degraded by her love of power and riches, dishonoured in the eyes of the people by the venal use which she made of the doctrine of life; the Church which sold salvation in order to fill a treasury, for luxury and debauchery to empty, had lost all respect. Men of sense no longer set any value on her testimony, but, despising an authority so degraded, turned with joy, towards the Divine word, and its infallible authority, as toward the only refuge which remained to them in the general confusion. The age, therefore, was prepared. The bold movement by which Luther changed the point on which the human heart rested its highest hopes, and with a mighty hand transferred those hopes from the walls of the Vatican to the rock of the word of God, was hailed with enthusiasm. This was the work which the Reformer had in view in his reply to Prierio.
