The beginnings of A Class in Wonders could be tracked back once again to the effort between two individuals, Helen Schucman and Bill Thetford, both of whom were prominent psychologists and researchers. The course's inception happened in the early 1960s when Schucman, who was a medical and study psychologist at Columbia University's School of Physicians and Surgeons, began to see a series of internal dictations. She identified these dictations as originating from an internal style that discovered itself as Jesus Christ. Schucman initially resisted these activities, but with Thetford's support, she began transcribing the messages she received.

Around an amount of seven decades, Schucman transcribed what might become A Class in Miracles, amounting to three sizes: the Text, the Workbook for Students, and the Manual for Teachers. The Text sits out the theoretical foundation of the program, elaborating on the core methods and principles. The Workbook for Pupils contains 365 instructions, one for each day  a course in miracles  of the entire year, made to steer the reader through a daily exercise of using the course's teachings. The Handbook for Educators offers more guidance on how to understand and show the maxims of A Program in Wonders to others.

One of the central themes of A Course in Wonders is the notion of forgiveness. The program teaches that correct forgiveness is the main element to internal peace and awareness to one's heavenly nature. In accordance with their teachings, forgiveness is not only a ethical or ethical exercise but a fundamental change in perception. It requires making go of judgments, issues, and the belief of sin, and alternatively, viewing the world and oneself through the contact of enjoy and acceptance. A Course in Miracles emphasizes that true forgiveness results in the recognition that we are all interconnected and that separation from each other is an illusion.

Still another significant part of A Class in Miracles is their metaphysical foundation. The class presents a dualistic view of reality, distinguishing involving the confidence, which shows divorce, fear, and illusions, and the Holy Heart, which symbolizes love, reality, and spiritual guidance. It implies that the vanity is the source of putting up with and struggle, as the Holy Spirit provides a pathway to therapeutic and awakening. The goal of the class is to help persons surpass the ego's limited perception and align with the Sacred Spirit's guidance.
