Great quote here:
Some of the priests, like Father Samaan of Cairo, have acquired such a reputation for their ability to exorcise demonsand evil spirits that I once witnessed the arrival of a Muslim woman, with her mentally disturbed daughter, who had traveled all the way from Syria to seek his aid.
