The roots of A Course in Wonders may be tracked 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 occurred in the early 1960s when Schucman, who had been a medical and research psychiatrist at Columbia University's School of Physicians and Surgeons, began to see a series of inner dictations. She described these dictations as coming from an internal voice that discovered it self as Jesus Christ. Schucman originally resisted these activities, but with Thetford's support, she began transcribing the messages she received.

Over a period of eight decades, Schucman transcribed what can become A Class in Miracles, amounting to three quantities: the Un Curso de Milagros Videos Text, the Book for Students, and the Manual for Teachers. The Text sits out the theoretical foundation of the course, elaborating on the key methods and principles. The Book for Pupils includes 365 classes, one for every day of the entire year, designed to guide the audience through a everyday practice of using the course's teachings. The Handbook for Teachers gives further advice on the best way to understand and train the maxims of A Class in Wonders to others.

Among the central subjects of A Program in Miracles is the idea of forgiveness. The class shows that true forgiveness is the main element to inner peace and awareness to one's divine nature. According to their teachings, forgiveness isn't simply a moral or honest training but a simple change in perception. It involves making get of judgments, grievances, and the belief of failure, and as an alternative, seeing the entire world and oneself through the lens of enjoy and acceptance. A Program in Wonders emphasizes that correct forgiveness contributes to the acceptance that we are typical interconnected and that divorce from each other is an illusion.

Still another substantial aspect of A Course in Miracles is their metaphysical foundation. The class gifts a dualistic view of fact, unique between the confidence, which represents separation, fear, and illusions, and the Holy Spirit, which symbolizes love, truth, and spiritual guidance. It implies that the pride is the source of putting up with and conflict, while the Holy Soul offers a pathway to therapeutic and awakening. The goal of the class is to greatly help persons surpass the ego's limited perspective and align with the Holy Spirit's guidance.
