 , Catholic medics have asserted that there have been 67 miracles and 7,000 unexplainable medical cures at Lourdes since 1858.In a 1908 book, it says these cures were subjected to intense medical scrutiny and were only recognized as authentic spiritual cures after a commission of doctors and scientists, called the Lourdes Medical Bureau, had ruled out any physical mechanism for the patient's recovery.In some Pentecostal and Charismatic Evangelical churches, a special place is thus reserved for faith healings with laying on of hands during worship services or for campaigns evangelization.
