“A time came when the Catholics, having long relied on force, were compelled to appeal to opinion. That which had been defiantly acknowledged and defended required to be ingeniously explained away. The same motive which had justified the murder now prompted the lie. Men shrank from the conviction that the rulers and restorers of their Church had been murderers and abetters of murder, and that so much infamy had been coupled with so much zeal. They feared to say that the most monstrous of crimes had been solemnly approved at Rome, lest they should devote the Papacy to the execration of mankind. A swarm of facts were invented to meet the difficulty: The victims were insignificant in number; they were slain for no reason connected with religion; the Pope believed in the existence of the plot; the plot was a reality; the medal is fictitious; the massacre was a feint concerted with the Protestants themselves; the Pope rejoiced only when he heard that it was over. These things were repeated so often that they have been sometimes believed; and men have fallen into this way of speaking whose sincerity was unimpeachable, and who were not shaken in their religion by the errors or the vices of Popes. Möhler was pre-eminently such a man. In his lectures on the history of the Church, which were published only last year, he said that the Catholics, as such, took no part in the massacre; that no cardinal, bishop, or priest shared in the councils that prepared it; that Charles informed the Pope that a conspiracy had been discovered; and that Gregory made his thanksgiving only because the King's life was saved. Such things will cease to be written when men perceive that truth is the only merit that gives dignity and worth to history.”
