The sources of A Program in Miracles could be traced back again to the relationship between two individuals, Helen Schucman and Bill Thetford, both of whom were distinguished psychologists and researchers. The course's inception occurred in early 1960s when Schucman, who had been a medical and research psychologist at Columbia University's University of Physicians and Surgeons, started to see a series of inner dictations. She defined these dictations as via an internal style that determined itself as Jesus Christ. Schucman originally resisted these activities, but with Thetford's encouragement, she started transcribing the messages she received.

Over an amount of eight decades, Schucman transcribed what might become A Course in Wonders, amounting to three volumes: the Text, the Workbook for Students, and the Guide for Teachers. The Text lies out the theoretical A Course In Miracles basis of the program, elaborating on the key ideas and principles. The Workbook for Students contains 365 instructions, one for every time of the season, designed to guide the audience through a day-to-day exercise of applying the course's teachings. The Information for Teachers gives more advice on how best to realize and show the axioms of A Class in Wonders to others.

One of many key themes of A Course in Miracles is the notion of forgiveness. The class shows that correct forgiveness is the important thing to internal peace and awakening to one's heavenly nature. Based on their teachings, forgiveness is not simply a ethical or moral practice but a basic change in perception. It requires letting move of judgments, issues, and the belief of crime, and alternatively, viewing the world and oneself through the lens of enjoy and acceptance. A Course in Miracles stresses that correct forgiveness leads to the acceptance that individuals are typical interconnected and that separation from one another can be an illusion.

Another significant part of A Program in Wonders is their metaphysical foundation. The program presents a dualistic see of reality, distinguishing between the vanity, which presents separation, fear, and illusions, and the Holy Nature, which symbolizes love, reality, and religious guidance. It implies that the ego is the source of putting up with and struggle, while the Sacred Soul provides a pathway to therapeutic and awakening. The goal of the program is to help persons transcend the ego's confined perception and align with the Sacred Spirit's guidance.
