The sources of A Course in Wonders may be traced back again to the collaboration between two individuals, Helen Schucman and William Thetford, equally of whom were prominent psychologists and researchers. The course's inception happened in early 1960s when Schucman, who had been a scientific and research psychologist at Columbia University's School of Physicians and Surgeons, started to have some inner dictations. She defined these dictations as originating from an internal style that determined itself as Jesus Christ. Schucman initially resisted these activities, but with Thetford's support, she began transcribing the communications she received.

Over an amount of seven years, Schucman transcribed what might become A Class in Miracles, amounting to three sizes: the Text, the Workbook for Students, and the Information for Teachers. The Text lays out the theoretical basis acim internships of the course, elaborating on the primary methods and principles. The Book for Students includes 365 lessons, one for every day of the year, designed to steer the reader via a everyday practice of applying the course's teachings. The Handbook for Educators provides further advice on how to realize and show the axioms of A Class in Wonders to others.

One of the key themes of A Class in Wonders is the thought of forgiveness. The class shows that correct forgiveness is the main element to inner peace and awakening to one's heavenly nature. In accordance with its teachings, forgiveness isn't merely a moral or honest training but a basic shift in perception. It involves allowing go of judgments, issues, and the notion of crime, and alternatively, seeing the world and oneself through the contact of love and acceptance. A Program in Miracles highlights that correct forgiveness results in the recognition that people are all interconnected and that separation from one another is definitely an illusion.

Yet another significant part of A Class in Wonders is their metaphysical foundation. The class gift suggestions a dualistic view of fact, unique between the ego, which shows separation, concern, and illusions, and the Holy Nature, which symbolizes love, reality, and religious guidance. It shows that the ego is the origin of enduring and conflict, as the Holy Spirit offers a pathway to therapeutic and awakening. The target of the course is to help individuals transcend the ego's confined perception and arrange with the Sacred Spirit's guidance.
