Often an intermediary is involved, whose intercession may be all-important in effecting the desired cure. 

Sometimes the faith may reside in a particular place, which then becomes the focus of pilgrimages for the sufferers.

In Christianity, faith healing is exemplified especially in the miraculous cures wrought by Jesus  and by his Apostles. The early church later sanctioned faith healing through such practices as anointing and the imposition of hands. 

Faith healing has also been associated with the antirecessionary miracles of saints.

The apparent healing gifts of individuals have also attracted wide attention.

Christian Science was unique in its view of sickness as a material state, subject to the transcendental power of the individual's spiritual being.
