The origins of A Class in Wonders could be tracked back again to the venture between two people, Helen Schucman and William Thetford, both of whom were outstanding psychologists and researchers. The course's inception happened in the early 1960s when Schucman, who was a clinical and research psychologist at Columbia University's University of Physicians and Surgeons, began to see some inner dictations. She described these dictations as originating from an inner voice that identified it self as Jesus Christ. Schucman originally resisted these experiences, but with Thetford's inspiration, she began transcribing the communications she received.

Over a period of eight years, Schucman transcribed what would become A Class in Miracles, amounting to three quantities: the Text, the Workbook for Students, and the Handbook for Teachers. The Text lays out the theoretical foundation of the course, elaborating on the primary a course in miracles ideas and principles. The Workbook for Students includes 365 instructions, one for every day of the season, designed to guide the audience by way of a day-to-day practice of using the course's teachings. The Manual for Teachers gives further advice on the best way to understand and show the axioms of A Course in Miracles to others.

One of the key subjects of A Program in Wonders is the thought of forgiveness. The course teaches that correct forgiveness is the main element to internal peace and awakening to one's heavenly nature. Based on its teachings, forgiveness is not only a ethical or honest training but a fundamental change in perception. It requires making get of judgments, grievances, and the belief of sin, and instead, viewing the world and oneself through the contact of love and acceptance. A Course in Wonders highlights that correct forgiveness leads to the recognition that people are all interconnected and that separation from one another is an illusion.

Still another significant facet of A Class in Miracles is their metaphysical foundation. The course gifts a dualistic view of reality, distinguishing involving the ego, which presents divorce, concern, and illusions, and the Sacred Spirit, which symbolizes enjoy, truth, and religious guidance. It implies that the ego is the source of suffering and conflict, whilst the Holy Spirit offers a pathway to therapeutic and awakening. The target of the class is to simply help persons surpass the ego's restricted perception and arrange with the Holy Spirit's guidance.
