The extremely unfavourable influence the Catholic Church long exercised upon intellectual development had important moral consequences. Although moral progress does not necessarily depend upon intellectual progress it is materially affected by it, intellectual activity being the most important element in the growth of that great and complex organism which we call civilisation. The mediæval credulity had also a more direct moral influence in producing that indifference to truth, which is the most repulsive feature of so many Catholic writings. The very large part that must be assigned to deliberate forgeries in the early apologetic literature of the Church we have already seen; and no impartial reader can, I think, investigate the innumerable grotesque and lying legends that, during the whole course of the Middle Ages, were deliberately palmed upon mankind as undoubted facts, can follow the histories of the false decretals, and the discussions that were connected with them, or can observe the complete and absolute incapacity most Catholic historians have displayed, of conceiving any good thing in the ranks of their opponents, or of stating with common fairness any consideration that can tell against their cause, without acknowledging how serious and how inveterate has been the evil. There have, no doubt, been many noble individual exceptions. Yet it is, I believe, difficult to exaggerate the extent to which this moral defect exists in most of the ancient and very much of the modern literature of Catholicism. It is this which makes it so unspeakably repulsive to all independent and impartial thinkers, and has led a great German historian(436) to declare, with much bitterness, that the phrase Christian veracity deserves to rank with the phrase Punic faith. But this absolute indifference to truth whenever falsehood could subserve the interests of the Church is perfectly explicable, and was found in multitudes who, in other respects, exhibited the noblest virtue. An age which has ceased to value impartiality of judgment will soon cease to value accuracy of statement; and when credulity is inculcated as a virtue, falsehood will not long be stigmatised as a vice. When, too, men are firmly convinced that salvation can only be found within their Church, and that their Church can absolve from all guilt, they will speedily conclude that nothing can possibly be wrong which is beneficial to it. They exchange the love of truth for what they call the love of _the_ truth. They regard morals as derived from and subordinate to theology, and they regulate all their statements, not by the standard of veracity, but by the interests of their creed.
