Add to this the dogma of papal infallibility, promulgated July 18, 1870, which asserts for the Pope "the entire plenitude of supreme power" to determine the faith and morals of Christians, and we have reached a point where it becomes plain to any thoughtful person that the Bible is, from the Catholic view-point, not at all such a necessary book as men have believed. Nor can the faith of a Romanist be a fixed and stable quantity. Any papal deliverance may bring about a change, and the conscientious Catholic must study the news from the Vatican with the same vital interest as the merchant studies the market reports in his morning paper, and a very pertinent question that he may ask his wife over his coffee at the breakfast table would be, "Wife, what do we believe to-day?" 12. Luther's Visit at Rome. Catholic writers ask the world not to believe Luther's tales about the city of Rome. Luther, they say, came to Rome as a callow rustic comes to a metropolis. To the wily Italians he was German Innocence Abroad; they hoaxed him by telling him absurd tales about the Popes, the priests, the wonders of the city, etc., and the credulous monk believed all they told him. He left Rome with his faith in the Church unimpaired. Later in life, after his "defection" from Rome, he told as true facts and as reminiscences of his visit at the Holy City many of the false stories which had been palmed off on him. This is said to have given rise to the prevailing Protestant view that during his visit at Rome Luther's eyes were opened to the corruption of the Roman Church and his resolution formed to overthrow that Church. Luther himself is said to be responsible for this false view. He fostered it by his tales of what he had seen and heard at Rome with disgust and horror. His horrid impressions are declared pure fiction, and simply serve to show how little the man can be trusted in anything he states.
