Enormous revenues flowed into various monasteries and churches in all parts of Europe from relics noted for their healing powers. The ecclesiastics perceived that the physician would interfere with these revenues and gifts of the shrines, and deemed it the will of God to persecute and condemn physicians. St. Ambrose declared, "The precepts of medicine are contrary to celestial science, watching and prayer." St. Augustine declared, "All diseases of Christians are to be ascribed to these demons, chiefly do they torment fresh baptized Christians, yea, even the guiltless, new-born babe." Gregory of Nazianzus declared that bodily pains are provoked by demons, and that medicines are useless, but that they are often cured by the laying on of consecrated hands. St. Niles and St. Gregory of Tours gave examples to show the sinfulness of resorting to medicine instead of trusting to the intercession of saints.
Even as late as 1517, Pope Leo X, for a consideration, issued tickets bearing a cross and the following inscription, "This cross measured forty times makes the height of Christ in His humanity. He who kisses it is preserved for seven days from falling sickness, apoplexy, and sudden death."
The Council of Le Mons, in 1248, forbade monks to engage in surgery. At the beginning of the twelfth century, the Council of Rheims forbade monks to study medicine; and shortly after the middle of the twelfth century, Pope Alexander III forbade monks to study or practice medicine. In the thirteenth century, the Dominican Order forbade all ecclesiastics to have any connection with medicine; and when we remember that the policy of the Church had made it impossible for any learned man to enter any other profession, the only resource left for a scholar was the Church; so effectively did the Church kill all scientific endeavors.
