The origins of A Program in Wonders may be followed back again to the cooperation between two persons, Helen Schucman and Bill Thetford, both of whom were distinguished psychologists and researchers. The course's inception occurred in early 1960s when Schucman, who was a clinical and research 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 inner style that determined it self as Jesus Christ. Schucman initially resisted these experiences, but with Thetford's support, she started transcribing the messages she received.

Around a period of seven decades, Schucman transcribed what would become A Program in Wonders, amounting to three quantities: the Text, the Workbook for Students, and the Manual for acim online Teachers. The Text lies out the theoretical basis of the class, elaborating on the primary concepts and principles. The Workbook for Students includes 365 lessons, one for each day of the entire year, designed to guide the audience by way of a daily exercise of applying the course's teachings. The Handbook for Teachers provides more advice on how best to understand and show the axioms of A Course in Wonders to others.

One of many main styles of A Course in Wonders is the idea of forgiveness. The class teaches that correct forgiveness is the important thing to inner peace and awareness to one's divine nature. In accordance with their teachings, forgiveness isn't simply a ethical or moral exercise but a essential change in perception. It requires allowing move of judgments, grievances, and the understanding of failure, and as an alternative, seeing the entire world and oneself through the lens of love and acceptance. A Course in Miracles stresses that true forgiveness results in the recognition that individuals are all interconnected and that divorce from one another can be an illusion.

Another significant part of A Class in Miracles is its metaphysical foundation. The program gift suggestions a dualistic view of truth, distinguishing involving the ego, which represents divorce, anxiety, and illusions, and the Sacred Heart, which symbolizes love, truth, and spiritual guidance. It shows that the confidence is the foundation of enduring and struggle, while the Holy Soul provides a pathway to therapeutic and awakening. The goal of the program is to help persons transcend the ego's limited perspective and align with the Sacred Spirit's guidance.
