The roots of A Course in Wonders could be traced back to the relationship between two individuals, Helen Schucman and William Thetford, both of whom were outstanding psychologists and researchers. The course's inception occurred in early 1960s when Schucman, who was a medical and study psychologist at Columbia University's School of Physicians and Surgeons, started to have some internal dictations. She described these dictations as via an interior style that recognized it self as Jesus Christ. Schucman originally resisted these activities, but with Thetford's encouragement, she began transcribing the communications she received.

Around a period of seven decades, Schucman transcribed what can become A Course in Wonders, amounting to three sizes: the Text, the Book for Pupils, and the Guide for Teachers. The Text sits out the theoretical base of the program, elaborating on the key concepts and principles. The Workbook for Pupils contains 365 instructions, one for each day of the year, made david hoffmeister  guide the audience via a day-to-day training of applying the course's teachings.
