The sources of A Class in Miracles can be followed back once again to the cooperation between two persons, Helen Schucman and Bill Thetford, both of whom were prominent psychologists and researchers. The course's inception happened in the first 1960s when Schucman, who was simply a medical and study psychologist at Columbia University's University of Physicians and Surgeons, began to have some inner dictations. She explained these dictations as coming from an internal style that recognized itself as Jesus Christ. Schucman originally resisted these activities, but with Thetford's inspiration, she started transcribing the messages she received.

Around a period of eight years,  a course in miracles transcribed what might become A Course in Miracles, amounting to three volumes: the Text, the Book for Pupils, and the Guide for Teachers. The Text sits out the theoretical foundation of the class, elaborating on the primary concepts and principles. The Book for Students includes 365 classes, one for each time of the season, designed to guide the audience via a day-to-day training of applying the course's teachings. The Manual for Teachers provides further advice on how best to realize and teach the maxims of A Class in Wonders to others.

One of the central themes of A Class in Wonders is the thought of forgiveness. The program shows that true forgiveness is the key to inner peace and awakening to one's heavenly nature. According to its teachings, forgiveness is not only a ethical or ethical training but a elementary shift in perception. It requires letting get of judgments, issues, and the notion of failure, and instead, seeing the world and oneself through the contact of enjoy and acceptance. A Program in Wonders stresses that true forgiveness results in the acceptance that people are typical interconnected and that separation from one another is an illusion.

Still another significant part of A Course in Wonders is their metaphysical foundation. The course gift suggestions a dualistic view of reality, unique involving the ego, which shows divorce, anxiety, and illusions, and the Holy Heart, which symbolizes love, reality, and religious guidance. It suggests that the ego is the source of enduring and conflict, while the Sacred Heart provides a pathway to healing and awakening. The target of the course is to greatly help individuals transcend the ego's limited perspective and align with the Holy Spirit's guidance.
