The beginnings of A Course in Wonders could be traced back to the effort between two people, Helen Schucman and Bill Thetford, equally of whom were prominent psychologists and researchers. The course's inception happened in the early 1960s when Schucman, who was simply a scientific and study psychologist at Columbia University's College of Physicians and Surgeons, started to have some internal dictations. She identified these dictations as originating from an internal voice that discovered itself as Jesus Christ. Schucman originally resisted these activities, but with Thetford's encouragement, she began transcribing the messages she received.

Around a period of seven decades, Schucman transcribed what can become A Course in Miracles, amounting to three amounts: the Text, the Workbook for Pupils, and the Guide for Teachers. The Text sits out the theoretical basis of the class, elaborating on the primary concepts and principles. The Book for Pupils includes 365 lessons, one for every time of the year, made to guide the reader via a everyday exercise of using the course's teachings. The Guide for Teachers provides more advice on how best to understand and teach the axioms of A Program in Wonders to others.

One of the central subjects of A Course in Miracles is the notion of forgiveness. The program teaches that true forgiveness is the main element to internal peace and awakening to one's heavenly nature. According to its teachings, forgiveness isn't merely a nothing I see means anything or moral practice but a basic shift in perception. It requires making go of judgments, grievances, and the belief of crime, and instead, seeing the entire world and oneself through the contact of enjoy and acceptance. A Program in Wonders emphasizes that correct forgiveness leads to the acceptance that people are interconnected and that divorce from each other is an illusion.

Still another substantial part of A Class in Wonders is their metaphysical foundation. The program presents a dualistic view of truth, distinguishing involving the ego, which presents separation, concern, and illusions, and the Holy Spirit, which symbolizes love, truth, and spiritual guidance. It suggests that the vanity is the origin of suffering and struggle, whilst the Sacred Spirit provides a pathway to healing and awakening. The target of the program is to simply help persons surpass the ego's restricted perception and arrange with the Sacred Spirit's guidance.
