The sources of A Course in Wonders can be traced back again to the relationship between two people, Helen Schucman and William Thetford, both of whom were prominent psychologists and researchers. The course's inception happened in early 1960s when Schucman, who was a medical and study psychiatrist at Columbia University's University of Physicians and Surgeons, started to have a series of internal dictations. She explained these dictations as via an inner voice that recognized itself as Jesus Christ. Schucman initially resisted these activities, but with Thetford's encouragement, she began transcribing the messages she received.

Around a period of eight years, Schucman transcribed what can become A Program in Miracles, amounting to three sizes: the Text, the Book for Pupils, and the Information for Teachers. The Text a course in miracles lies out the theoretical base of the class, elaborating on the core ideas and principles. The Workbook for Students includes 365 classes, one for each time of the season, made to steer the reader by way of a day-to-day practice of applying the course's teachings. The Handbook for Educators gives more advice on how best to understand and train the maxims of A Program in Miracles to others.

One of the central themes of A Class in Wonders is the thought of forgiveness. The course teaches that true forgiveness is the key to internal peace and awareness to one's divine nature. According to their teachings, forgiveness is not only a ethical or moral exercise but a basic shift in perception. It involves making go of judgments, issues, and the perception of failure, and alternatively, seeing the entire world and oneself through the contact of enjoy and acceptance. A Program in Miracles highlights that true forgiveness contributes to the recognition that we are all interconnected and that separation from each other is definitely an illusion.

Another substantial facet of A Program in Miracles is their metaphysical foundation. The program gift suggestions a dualistic view of fact, distinguishing involving the ego, which shows divorce, fear, and illusions, and the Holy Soul, which symbolizes enjoy, truth, and spiritual guidance. It shows that the pride is the origin of putting up with and conflict, as the Holy Nature supplies a pathway to therapeutic and awakening. The goal of the course is to help individuals transcend the ego's confined perspective and align with the Holy Spirit's guidance.
