Much of the ill success with which the Crusaders met during several of these expeditions, may be traced to jealousies and heart-burnings between the different princes and nobles who took part in them, whilst disagreements on a larger scale were amongst the evil fruits of the unhappy division between Eastern and Western Christendom. Latin Christians appear in too many instances to have made use of the opportunities afforded them to injure and oppress their weaker brethren of the Greek Church, even whilst marching against the common foe of both, and the Fourth Crusade (A.D. 1203) was actually diverted from its legitimate purpose in order to conquer Constantinople, and establish a Latin Emperor, as well as a Latin Patriarch within its walls.
Good directly brought about by them.
Still, whatever may have been the want of single-mindedness on the part of many of the professed soldiers of the Cross, whatever the amount of failure with regard to the immediate objects of the Crusades, it is clear that much good was brought about through them by God's Providence, not only in the check given to the encroachments of the unbelievers, but also more indirectly in the quenching of rising heresies, in the greater purity of life which in many cases accompanied the taking of the Cross, the weakening of the feudal system, the impulse given to learning and civilization. Earnestness and self-devotion such as were shown by Godfrey de Bouillon, St. Louis of France, and no doubt by many more amongst the Crusaders, were rewarded and blessed, though not in what might have seemed at first sight the only way of success.
Section 5. State of Religions Relief and Practice during the Middle Ages.
Popular idea of the Middle Ages,
There is a wide-spread notion that the Middle Ages were also "Dark Ages," full of ignorance and superstition, with hardly a ray of knowledge or true religion to enlighten the gloom, and also that the Church was the great encourager of this state of things; indeed, that it was mainly due to the influence of the monks and of the Clergy generally.
not founded in history.
This belief is however quite unhistorical. No doubt there was abundance of ignorance as well as of superstition, its natural consequence, but there are ample means of accounting for both in the political condition of Europe at that time, nor is it needful to blame the Church for what was in fact due to the sins and errors of the world.
