The extent to which the custom of materialising religion was carried, can only be adequately realised by those who have examined the mediæval literature itself. That which strikes a student in perusing this literature, is not so much the existence of these superstitions, as their extraordinary multiplication, the many thousands of grotesque miracles wrought by saints, monasteries, or relics, that were deliberately asserted and universally believed. Christianity had assumed a form that was quite as polytheistic and quite as idolatrous as the ancient Paganism. The low level of intellectual cultivation, the religious feelings of half-converted barbarians, the interests of the clergy, the great social importance of the monasteries, and perhaps also the custom of compounding for nearly all crimes by pecuniary fines, which was so general in the penal system of the barbarian tribes, combined in their different ways, with the panic created by the fear of hell, in driving men in the same direction, and the wealth and power of the clergy rose to a point that enabled them to overshadow all other classes. They had found, as has been well said, in another world, the standing-point of Archimedes from which they could move this. No other system had ever appeared so admirably fitted to endure for ever. The Church had crushed or silenced every opponent in Christendom. It had an absolute control over education in all its branches and in all its stages. It had absorbed all the speculative knowledge and art of Europe. It possessed or commanded wealth, rank, and military power. It had so directed its teaching, that everything which terrified or distressed mankind drove men speedily into its arms, and it had covered Europe with a vast network of institutions, admirably adapted to extend and perpetuate its power. In addition to all this, it had guarded with consummate skill all the approaches to its citadel. Every doubt was branded as a sin, and a long course of doubt must necessarily have preceded the rejection of its tenets. All the avenues of enquiry were painted with images of appalling suffering, and of malicious dæmons. No sooner did the worshipper begin to question any article of faith, or to lose his confidence in the virtue of the ceremonies of his Church, than he was threatened with a doom that no human heroism could brave, that no imagination could contemplate undismayed.
