Not surprisingly, due to this widespread use of charms throughout the ancient world, the early Christian church eventually inherited the use of amulets. The usual inscription on these Christian charms was, "ichthys," the Greek word for "fish". This word was chosen because it contained the initials of the Greek words for Jesus Christ, Son of God, and Savior. Christians sometimes wore a copy of St. Johns Gospel on a cross or necklace, or put a copy of the Lords Prayer in their shoes. (Microsoft Encarta Encyclopedia 2000, titled "Amulet")[snip]Amulets became so common among Christians that in the fourth century AD the clergy were forbidden to make or sell them in fear of deprivation of holy orders. In the 7th century the wearing of amulets was solemnly condemned. (Microsoft Encarta Encyclopedia 2000) This condemnation did little to stop or slow the popularity of amulets. Unceasing faith in charms was to continue for many hundreds of years.
Acts 19: 11-12
God did extraordinary miracles through Paul, so that even handkerchiefs and aprons that had touched him were taken to the sick, and their illnesses were cured and the evil spirits left them.
