The beginnings of A Program in Miracles can be tracked back again to the collaboration between two people, Helen Schucman and William Thetford, equally of whom were outstanding psychologists and researchers. The course's inception occurred in the early 1960s when Schucman, who was simply a medical and research psychologist at Columbia University's College of Physicians and Surgeons, started to experience some inner dictations. She described these dictations as via an internal voice that discovered it self as Jesus Christ. Schucman initially resisted these activities, but with Thetford's inspiration, she started transcribing the communications she received.

Over a period of seven decades, Schucman transcribed what can become A Program in Wonders, amounting to three amounts: the Text, the acim shop Book for Pupils, and the Guide for Teachers. The Text lays out the theoretical basis of the class, elaborating on the core ideas and principles. The Workbook for Pupils contains 365 classes, one for each day of the season, designed to guide the reader through a day-to-day exercise of applying the course's teachings. The Information for Teachers offers more advice on the best way to understand and teach the maxims of A Course in Wonders to others.

One of many central subjects of A Class in Wonders is the notion of forgiveness. The class teaches that correct forgiveness is the main element to inner peace and awareness to one's divine nature. According to its teachings, forgiveness is not only a moral or ethical exercise but a fundamental shift in perception. It requires making get of judgments, issues, and the perception of failure, and alternatively, viewing the world and oneself through the contact of enjoy and acceptance. A Class in Wonders emphasizes that correct forgiveness results in the recognition that individuals are typical interconnected and that divorce from each other is an illusion.

Another substantial part of A Class in Wonders is its metaphysical foundation. The class gift ideas a dualistic view of fact, unique between the pride, which represents divorce, anxiety, and illusions, and the Sacred Nature, which symbolizes love, reality, and spiritual guidance. It implies that the pride is the foundation of suffering and conflict, as the Sacred Spirit offers a pathway to therapeutic and awakening. The target of the program is to simply help people surpass the ego's restricted perception and align with the Holy Spirit's guidance.
