It was to our Lord Himself that the theologians attributed all merit; but in the popular mind the merits of the saints took an ever more important place, since the Church seemed to make the priesthood a barrier against, rather than a channel for, the flow of God's mercy to man; but popular feeling sought to find intercessors before the throne of grace in the holy men and women of the faith. For a long time it was the bishops who decided the title to saintship. But in 993 Pope John XV, in a Council at Rome and in response to a request of the Bishop of Augsburg, ordered that a former bishop of that see should be venerated as a saint. This was the process afterwards called Canonisation, which involved the insertion of a name in the Canon or list, and gave it currency not merely in a single diocese, but throughout western Christendom. In 1170 Alexander III claimed such recognition as the exclusive right of Rome. But despite this assumption of authority, popular feeling very often dictated to the Pope whom he should admit into the list. Death followed by miracles at the tomb, and sometimes the building of an elaborate shrine with an altar, forced the Pope to grant the claims of a popular favourite. [Sidenote: Miracles and relics.] A rapid increase in the number of applications for such official recognition would be the result of any widely popular movement. Such was the effect of the Crusades in the twelfth century, and of the foundation of the Mendicant Orders in the thirteenth. And the multiplication of saints meant an increase in the number of relics and an ever-growing belief in the miraculous. Miracles frequently took place in connection with living persons of saintly life. Abailard scornfully pointed out that some of the attempts made by Norbert or Bernard to work miraculous cures were quite unsuccessful, while in successful cases medicine as well as prayers had been employed. But such rationalism was beyond the grasp of an ignorant age, and collections of stories of miracles, such as remain to us in the "Golden Legends" of Jacob de Voragine, a Dominican of the thirteenth century, fed the popular belief. Miracles so commemorated often occurred in connection with relics; and the traffic in relics and so styled "pious" frauds, not to say the forcible means used to procure reputed relics of authentic or supposititious saints, forms a curious if a discreditable feature in mediæval history. An occasional protest was uttered against the manner in which credit was often obtained for relics of more than doubtful authenticity; but the manufacture of them was easy and profitable, and pilgrims returning from Palestine could palm off anything upon the credulity of a willing and ignorant populace. The growth of a legend in connection with relics is fitly illustrated by the history of the eleven thousand Virgins of Köln. Martyrologies of the ninth century celebrate the martyrdom of eleven virgins in the city of Köln. Perhaps these were described as XI.
