The roots of A Program in Miracles may be followed back to the cooperation between two individuals, Helen Schucman and Bill Thetford, equally of whom were prominent psychologists and researchers. The course's inception happened in the first 1960s when Schucman, who was a scientific and study psychiatrist at Columbia University's College of Physicians and Surgeons, started to have a series of inner dictations. She explained these dictations as originating from an interior style that discovered 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 eight years, Schucman transcribed what would become A Class in Miracles, amounting to three sizes: the Text, the Workbook for Pupils, and the Information for Teachers. The Text sits out the theoretical base of the program, elaborating on the key concepts and principles. The Book for Students contains 365 instructions, one for every day of the entire year,  a course in miracles  designed to steer the reader via a daily practice of using the course's teachings. The Handbook for Educators gives more guidance on how best to understand and teach the principles of A Course in Wonders to others.

One of the central subjects of A Program in Miracles is the idea of forgiveness. The program teaches that true forgiveness is the main element to internal peace and awakening to one's divine nature. Based on their teachings, forgiveness isn't merely a ethical or moral exercise but a fundamental change in perception. It requires letting move of judgments, grievances, and the belief of crime, and instead, seeing the planet and oneself through the lens of enjoy and acceptance. A Course in Miracles highlights that true forgiveness contributes to the recognition that individuals are typical interconnected and that separation from one another can be an illusion.

Yet another significant part of A Course in Wonders is its metaphysical foundation. The class gift suggestions a dualistic view of truth, distinguishing between the vanity, which shows separation, fear, and illusions, and the Sacred Nature, which symbolizes enjoy, reality, and spiritual guidance. It suggests that the ego is the source of suffering and struggle, whilst the Holy Spirit offers a pathway to therapeutic and awakening. The target of the course is to greatly help individuals surpass the ego's confined perspective and arrange with the Sacred Spirit's guidance.
