The roots of A Course in Miracles can be followed back once again to the collaboration between two individuals, Helen Schucman and Bill Thetford, both of whom were distinguished psychologists and researchers. The course's inception happened in the first 1960s when Schucman, who had been a scientific and study psychiatrist at Columbia University's School of Physicians and Surgeons, started to have a series of internal dictations. She defined these dictations as originating from an internal style that recognized itself as Jesus Christ. Schucman originally resisted these activities, but with Thetford's encouragement, she started transcribing the messages she received.

Over an amount of seven decades, Schucman transcribed what can become A Program in Wonders, amounting to three amounts: the Text, the Book for Students, and the Guide for Teachers. The Text lays out the theoretical foundation of the class, elaborating on the core concepts and principles. The Book for Pupils contains 365 classes, one for every day of the season, designed to guide the reader via a everyday training of using the course's teachings. The Information for Teachers gives more guidance on how best to understand and teach the concepts of A Course in Miracles to others.

One of the main subjects of A Program in Wonders is the thought of forgiveness. The course shows that true forgiveness is the important thing to inner peace and awakening to one's heavenly nature. Based on their teachings, forgiveness isn't merely a ethical acim honest training but a essential shift in perception. It involves making move of judgments, grievances, and the belief of failure, and alternatively, viewing the entire world and oneself through the lens of love and acceptance. A Class in Wonders emphasizes that true forgiveness leads to the recognition that individuals are all interconnected and that divorce from each other can be an illusion.

Another significant facet of A Class in Wonders is its metaphysical foundation. The class gifts a dualistic see of reality, distinguishing between the vanity, which presents separation, fear, and illusions, and the Sacred Nature, which symbolizes enjoy, truth, and religious guidance. It suggests that the vanity is the source of suffering and struggle, as the Holy Nature provides a pathway to therapeutic and awakening. The goal of the program is to help persons surpass the ego's confined perception and align with the Holy Spirit's guidance.
