The beginnings of A Class in Miracles could be tracked back to the relationship between two individuals, Helen Schucman and Bill Thetford, equally of whom were prominent psychologists and researchers. The course's inception happened in early 1960s when Schucman, who had been a clinical and study psychiatrist at Columbia University's College of Physicians and Surgeons, started to see a series of internal dictations. She identified these dictations as originating from an inner style that identified itself as Jesus Christ. Schucman originally resisted these experiences, but with Thetford's encouragement, she started transcribing the communications she received.

Around a period of seven years, Schucman transcribed what might become A Course in Wonders, amounting to three sizes: the Text, the Book for Pupils, and the Handbook for Teachers. The Text lies out the theoretical foundation of the program, elaborating on the core ideas and principles. The Workbook for Pupils includes 365 classes, one for each time of the entire year, designed to steer the audience through a day-to-day training of using the course's teachings. The Manual for Teachers gives more advice on how to realize and show the principles of A Class in Wonders to others.

One of the key subjects of A Program in Miracles is the notion of forgiveness. The class shows that correct forgiveness is the key to internal peace and awakening to one's heavenly nature. Based on its teachings, forgiveness isn't only a moral or honest exercise but a elementary change in perception. It involves making get of judgments, issues, and the notion of ucdm , and alternatively, seeing the entire world and oneself through the lens of love and acceptance. A Class in Wonders emphasizes that true forgiveness results in the acceptance that individuals are all interconnected and that divorce from each other is definitely an illusion.

Yet another significant part of A Program in Miracles is their metaphysical foundation. The course gift suggestions a dualistic see of truth, distinguishing between the ego, which shows divorce, concern, and illusions, and the Sacred Spirit, which symbolizes love, truth, and religious guidance. It implies that the pride is the origin of suffering and struggle, as the Holy Heart provides a pathway to therapeutic and awakening. The target of the class is to help people surpass the ego's restricted perception and arrange with the Holy Spirit's guidance.
