The sources of A Program in Wonders could be tracked back once again to the effort between two people, Helen Schucman and Bill Thetford, equally of whom were distinguished psychologists and researchers. The course's inception happened in the early 1960s when Schucman, who had been a medical and study psychologist at Columbia University's School of Physicians and Surgeons, started to have a series of inner dictations. She described these dictations as originating from an interior style that identified it self as Jesus Christ. Schucman initially resisted these activities, but with Thetford's support, she began transcribing the messages she received.

Around a period of seven decades, Schucman transcribed what would become A Course in Miracles, amounting to three sizes: the Text, the Workbook for Pupils, and the Manual for Teachers. The Text lays out the theoretical foundation of the class, elaborating on the core a course in miracles concepts and principles. The Workbook for Students contains 365 classes, one for each day of the entire year, developed to guide the reader by way of a daily practice of applying the course's teachings. The Handbook for Teachers offers more guidance on how to understand and show the rules of A Course in Miracles to others.

One of the main styles of A Course in Miracles is the thought of forgiveness. The program teaches that correct forgiveness is the main element to internal peace and awakening to one's heavenly nature. In accordance with its teachings, forgiveness isn't only a ethical or moral exercise but a elementary change in perception. It requires allowing move of judgments, grievances, and the understanding of failure, and instead, seeing the planet and oneself through the contact of love and acceptance. A Program in Miracles stresses that correct forgiveness results in the acceptance that we are typical interconnected and that separation from each other is definitely an illusion.

Yet another substantial aspect of A Course in Miracles is its metaphysical foundation. The program presents a dualistic see of reality, distinguishing between the ego, which represents divorce, fear, and illusions, and the Holy Heart, which symbolizes enjoy, reality, and spiritual guidance. It implies that the vanity is the origin of putting up with and struggle, while the Holy Spirit offers a pathway to healing and awakening. The target of the course is to greatly help individuals surpass the ego's confined perception and align with the Sacred Spirit's guidance.
