Mary Baker Eddy, the founder of Christian Science, had some controversial approaches, but her writings shed light on the power of prayer and divine love to heal the body and the soul.  

“Forsaking matter for Spirit by no means suggests man’s absorption into Deity and the loss of his identity, but confers upon man enlarged individuality, a wider sphere of thought and action, a more expansive love, a higher and more permanent peace.”
Mary Baker Eddy
