The origins of A Course in Miracles could be followed back to the effort between two people, Helen Schucman and Bill Thetford, equally of whom were outstanding psychologists and researchers. The course's inception happened in the first 1960s when Schucman, who had been a clinical and research psychologist at Columbia University's School of Physicians and Surgeons, began to see some internal dictations. She identified these dictations as originating from an internal voice that recognized it self as Jesus Christ. Schucman initially resisted these experiences, but with Thetford's support, she began transcribing the messages she received.

Over a period of eight decades, Schucman transcribed what would become A Class in Wonders, amounting to three sizes: the Text, the Book for Students, and the Handbook for Teachers. The Text sits out the theoretical foundation of the class, elaborating on the key concepts and principles. The Workbook for Pupils contains 365 instructions, one for every time of the year, made to steer the audience by way of a daily practice of applying the course's teachings. The Manual for Teachers provides further guidance on the best way to understand and show the principles of A Program in Wonders to others.

One of many key styles of A Class in Wonders is the thought of forgiveness. The class teaches that correct forgiveness is the important thing to internal peace and awakening to one's divine nature. According to its teachings, forgiveness isn't merely a course in miracles  a ethical or honest training but a basic change in perception. It requires making go of judgments, issues, and the notion of failure, and as an alternative, seeing the entire world and oneself through the lens of love and acceptance. A Course in Wonders emphasizes that correct forgiveness results in the recognition that people are all interconnected and that separation from one another can be an illusion.

Still another substantial part of A Course in Miracles is their metaphysical foundation. The course gift ideas a dualistic view of fact, unique between the vanity, which represents divorce, fear, and illusions, and the Holy Nature, which symbolizes enjoy, reality, and spiritual guidance. It implies that the confidence is the origin of enduring and struggle, whilst the Holy Nature offers a pathway to healing and awakening. The target of the course is to help people transcend the ego's confined perception and arrange with the Sacred Spirit's guidance.
