The beginnings of A Program in Wonders can be followed back to the cooperation between two individuals, Helen Schucman and William Thetford, equally of whom were prominent psychologists and researchers. The course's inception occurred in the first 1960s when Schucman, who was simply a medical and study psychologist at Columbia University's University of Physicians and Surgeons, began to have a series of inner dictations. She described these dictations as via an interior voice that identified itself as Jesus Christ. Schucman initially resisted these experiences, but with Thetford's support, she started transcribing the messages she received.

Around a period of eight years, Schucman transcribed what might become A Course in Wonders, amounting to three volumes: the Text, the A Course In Miracles Book for Pupils, and the Handbook for Teachers. The Text sits out the theoretical base of the course, elaborating on the key ideas and principles. The Workbook for Students contains 365 lessons, one for every time of the year, designed to steer the audience through a daily training of using the course's teachings. The Manual for Teachers gives further guidance on how best to understand and show the maxims of A Class in Miracles to others.

One of the key subjects of A Program in Wonders is the notion of forgiveness. The course shows that correct forgiveness is the key to inner peace and awakening to one's heavenly nature. In accordance with their teachings, forgiveness is not only a moral or honest training but a essential shift in perception. It involves making move of judgments, issues, and the belief of sin, and alternatively, seeing the world and oneself through the lens of love and acceptance. A Class in Wonders emphasizes that correct forgiveness contributes to the recognition that we are all interconnected and that divorce from each other is an illusion.

Another significant facet of A Course in Miracles is their metaphysical foundation. The class gift suggestions a dualistic see of fact, distinguishing involving the vanity, which presents divorce, concern, and illusions, and the Holy Spirit, which symbolizes enjoy, reality, and spiritual guidance. It implies that the ego is the origin of putting up with and struggle, as the Sacred Spirit offers a pathway to healing and awakening. The target of the program is to help people transcend the ego's limited perception and align with the Sacred Spirit's guidance.
