The beginnings of A Program in Wonders can be traced back once again to the collaboration between two individuals, Helen Schucman and William 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 study psychiatrist at Columbia University's University of Physicians and Surgeons, began to have a series of internal dictations. She defined these dictations as originating from an interior voice that determined it self as Jesus Christ. Schucman originally resisted these activities, but with Thetford's encouragement, she began transcribing the communications she received.

Over an amount of eight years, Schucman transcribed what might become A Course in Wonders, amounting to three sizes: the Text, the Workbook for Pupils, and the Guide for Teachers. The Text lays out the theoretical basis of the acim class, elaborating on the primary concepts and principles. The Book for Pupils includes 365 lessons, one for every single time of the season, made to guide the reader by way of a daily exercise of applying the course's teachings. The Handbook for Teachers gives more advice on the best way to realize and teach the rules of A Class in Wonders to others.

Among the key themes of A Program in Miracles is the idea of forgiveness. The program teaches that true forgiveness is the key to internal peace and awakening to one's divine nature. According to its teachings, forgiveness isn't only a ethical or honest practice but a basic shift in perception. It requires making get of judgments, grievances, and the perception of sin, and as an alternative, seeing the world and oneself through the lens of love and acceptance. A Class in Wonders emphasizes that true forgiveness results in the recognition that people are all interconnected and that divorce from each other can be an illusion.

Another significant part of A Class in Wonders is its metaphysical foundation. The course gift suggestions a dualistic see of fact, unique involving the ego, which represents separation, fear, and illusions, and the Sacred Nature, which symbolizes enjoy, truth, and religious guidance. It shows that the pride is the source of suffering and conflict, as the Holy Soul offers a pathway to therapeutic and awakening. The goal of the program is to greatly help persons surpass the ego's confined perspective and arrange with the Sacred Spirit's guidance.
