At their core, A Course in Miracles is really a channeled perform, and its origins are shrouded in mystery. Helen Schucman, a clinical psychiatrist, and William Thetford, a study psychologist, collaborated in the 1960s to transcribe the internal dictations that Schucman said to get from an interior voice she discovered as Jesus Christ. The method of getting and documenting these messages spanned seven decades and led to the three-volume guide called A Class in Miracles.
