The beginnings of A Program in Miracles may be traced back to the collaboration between two persons, Helen Schucman and Bill Thetford, equally of whom were distinguished psychologists and researchers. The course's inception occurred in early 1960s when Schucman, who had been a scientific and study psychiatrist at Columbia University's College of Physicians and Surgeons, started to experience a series of internal dictations. She defined these dictations as coming from an internal voice that determined itself as Jesus Christ. Schucman initially resisted these activities, but with Thetford's support, she started transcribing the messages she received.

Over an amount of seven decades, Schucman transcribed what might become A Program in Wonders, amounting to three sizes: the Text, the Book for Pupils, and the Manual for Teachers. The Text lies out the theoretical basis of the program, elaborating on the core the christ  and principles. The Book for Pupils contains 365 lessons, one for each time of the year, developed to steer the reader via a daily exercise of applying the course's teachings. The Handbook for Educators provides more guidance on how to realize and train the principles of A Program in Wonders to others.

Among the main styles of A Class in Miracles is the idea of forgiveness. The class shows that true forgiveness is the important thing to inner peace and awareness to one's divine nature. In accordance with their teachings, forgiveness isn't simply a moral or moral practice but a essential shift in perception. It involves allowing move of judgments, issues, and the perception of crime, and as an alternative, seeing the planet and oneself through the lens of enjoy and acceptance. A Program in Miracles stresses that true forgiveness contributes to the acceptance that individuals are interconnected and that divorce from each other can be an illusion.

Another substantial part of A Course in Wonders is its metaphysical foundation. The program gift suggestions a dualistic see of truth, unique between the pride, which represents separation, anxiety, and illusions, and the Holy Heart, which symbolizes love, reality, and spiritual guidance. It shows that the vanity is the origin of putting up with and struggle, as the Sacred Heart supplies a pathway to healing and awakening. The goal of the course is to greatly help people transcend the ego's confined perspective and align with the Sacred Spirit's guidance.
