The origins of A Course in Wonders could be traced back once again to the collaboration between two individuals, Helen Schucman and William Thetford, both of whom were prominent psychologists and researchers. The course's inception occurred in early 1960s when Schucman, who was a medical and research psychiatrist at Columbia University's College of Physicians and Surgeons, started to experience some internal dictations. She defined these dictations as coming from an inner voice that identified itself as Jesus Christ. Schucman originally resisted these experiences, but with Thetford's encouragement, she started transcribing the messages she received.

Around a period of eight years, Schucman transcribed what would become A Course in Wonders, amounting to three sizes: the Text, the Workbook for Pupils, and the Manual for Teachers. The Text lays out the theoretical base of the class, elaborating on the core acim online and principles. The Book for Pupils contains 365 lessons, one for every time of the year, developed to guide the audience by way of a day-to-day training of using the course's teachings. The Information for Educators provides further advice on how to realize and teach the principles of A Course in Wonders to others.

Among the central subjects of A Class in Miracles is the notion of forgiveness. The program shows that correct forgiveness is the key to inner peace and awakening to one's heavenly nature. According to its teachings, forgiveness isn't simply a ethical or moral training but a elementary shift in perception. It requires allowing go of judgments, issues, and the belief of failure, and instead, seeing the entire world and oneself through the lens of love and acceptance. A Course in Wonders emphasizes that correct forgiveness results in the acceptance that we are interconnected and that divorce from each other can be an illusion.

Still another significant aspect of A Program in Miracles is their metaphysical foundation. The class gift suggestions a dualistic see of fact, unique between the pride, which represents divorce, concern, and illusions, and the Holy Heart, which symbolizes love, truth, and religious guidance. It suggests that the pride is the foundation of putting up with and struggle, whilst the Holy Nature provides a pathway to healing and awakening. The target of the course is to greatly help persons transcend the ego's confined perception and align with the Sacred Spirit's guidance.
