The origins of A Course in Miracles could be tracked back once again to the venture between two people, Helen Schucman and Bill Thetford, both of whom were outstanding psychologists and researchers. The course's inception happened in early 1960s when Schucman, who was a scientific and research psychiatrist at Columbia University's University of Physicians and Surgeons, started to have some internal dictations. She defined these dictations as via an internal style that identified it self as Jesus Christ. Schucman originally resisted these activities, but with Thetford's support, she began transcribing the communications she received.

Over an amount of seven decades, Schucman transcribed what would become A Program in Wonders, amounting to three sizes: the Text, the Book for Pupils, and the Guide for Teachers. The Text lies out the theoretical foundation of the class, elaborating on  the mystical teachings of Jesus primary ideas and principles. The Book for Pupils includes 365 lessons, one for every time of the entire year, designed to steer the audience through a daily exercise of using the course's teachings. The Handbook for Educators offers further guidance on the best way to understand and teach the rules of A Class in Wonders to others.

Among the key subjects of A Course in Wonders is the notion of forgiveness. The class shows that correct forgiveness is the key to internal peace and awakening to one's divine nature. In accordance with its teachings, forgiveness is not only a moral or honest exercise but a simple change in perception. It requires making get of judgments, issues, and the belief of crime, and instead, viewing the world and oneself through the lens of enjoy and acceptance. A Program in Wonders emphasizes that true forgiveness leads to the acceptance that individuals are typical interconnected and that separation from each other can be an illusion.

Still another significant part of A Program in Wonders is their metaphysical foundation. The class gift ideas a dualistic view of reality, distinguishing involving the pride, which presents separation, fear, and illusions, and the Holy Soul, which symbolizes love, reality, and spiritual guidance. It shows that the ego is the source of putting up with and struggle, while the Holy Heart provides a pathway to healing and awakening. The goal of the course is to greatly help individuals surpass the ego's confined perception and align with the Holy Spirit's guidance.
