The roots of A Class in Miracles can be tracked back again to the venture between two people, Helen Schucman and Bill Thetford, both of whom were prominent psychologists and researchers. The course's inception happened in early 1960s when Schucman, who was a clinical and research psychiatrist at Columbia University's University of Physicians and Surgeons, started to experience some inner dictations. She identified these dictations as originating from an internal style that determined itself as Jesus Christ. Schucman originally resisted these activities, but with Thetford's encouragement, she started transcribing the communications she received.

Around an amount of seven decades, Schucman transcribed what would become A Class in Miracles, amounting to three volumes: the Text, the Book for Pupils, and the Handbook for Teachers. The Text sits out the theoretical base of the class, elaborating on the a course in miracles key concepts and principles. The Workbook for Students includes 365 lessons, one for each day of the season, designed to guide the reader via a everyday exercise of using the course's teachings. The Manual for Educators gives further guidance on how to understand and teach the concepts of A Program in Wonders to others.

Among the central styles of A Program in Miracles is the thought of forgiveness. The program teaches that true forgiveness is the main element to internal peace and awareness to one's divine nature. Based on its teachings, forgiveness is not only a ethical or moral training but a essential change in perception. It requires letting move of judgments, grievances, and the understanding of crime, and as an alternative, viewing the entire world and oneself through the lens of love and acceptance. A Class in Miracles emphasizes that correct forgiveness results in the recognition that individuals are interconnected and that divorce from one another is an illusion.

Yet another significant facet of A Course in Miracles is its metaphysical foundation. The course presents a dualistic view of fact, unique between the ego, which shows divorce, concern, and illusions, and the Sacred Spirit, which symbolizes enjoy, reality, and spiritual guidance. It implies that the pride is the origin of enduring and struggle, as the Holy Heart supplies a pathway to therapeutic and awakening. The target of the program is to greatly help individuals surpass the ego's restricted perception and arrange with the Holy Spirit's guidance.
