The origins of A Course in Miracles can be traced back to the cooperation between two persons, Helen Schucman and Bill Thetford, equally of whom were outstanding psychologists and researchers. The course's inception occurred in the first 1960s when Schucman, who was simply a medical and study psychiatrist at Columbia University's College of Physicians and Surgeons, began to see some internal dictations. She defined these dictations as originating from an interior style that discovered it self as Jesus Christ. Schucman originally resisted these experiences, but with Thetford's support, she began transcribing the messages she received.

Around a period of eight years, Schucman transcribed what can become A Course in Miracles, amounting to three volumes: the Text, the Book for Students, and the Manual for Teachers. The Text sits out the theoretical basis of the program, elaborating on the core concepts and a course in miracles. The Workbook for Pupils contains 365 instructions, one for every time of the season, designed to steer the reader through a day-to-day exercise of using the course's teachings. The Manual for Educators provides more guidance on how to understand and teach the principles of A Program in Wonders to others.

One of the main subjects of A Course in Wonders is the thought of forgiveness. The program shows that true forgiveness is the main element to internal peace and awakening to one's heavenly nature. According to its teachings, forgiveness isn't simply a ethical or moral training but a fundamental shift in perception. It involves allowing go of judgments, issues, and the notion of failure, and instead, seeing the entire world and oneself through the lens of enjoy and acceptance. A Class in Miracles highlights that true forgiveness contributes to the recognition that people are interconnected and that separation from each other is an illusion.

Still another significant facet of A Course in Miracles is its metaphysical foundation. The class presents a dualistic view of truth, distinguishing between the pride, which represents separation, fear, and illusions, and the Holy Heart, which symbolizes love, reality, and religious guidance. It implies that the ego is the foundation of enduring and conflict, whilst the Holy Soul offers a pathway to healing and awakening. The goal of the program is to greatly help people surpass the ego's restricted perspective and align with the Sacred Spirit's guidance.
