A better-known individual was Phineas Quimby (1802-1866). He explored a combination of magnetism and hypnotism to create a type of “natural healing.” He actually mentored Mary Baker Eddy, who became a founder of the first major movement of healing through faith. This was the Christian Scientists.
Another group with faith as a basis for healing is more recent. This is the work founded by Kenneth E. Hagin (1917-2003), a prominent Pentecostal preacher. His approach is responsible for the more modern approach to healing through one’s faith.
