The origins of A Class in Wonders may be traced back to the collaboration between two individuals, Helen Schucman and William Thetford, both 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 College of Physicians and Surgeons, started to have a series of inner dictations. She defined these dictations as coming from an internal voice that identified itself as Jesus Christ. Schucman originally resisted these activities, but with Thetford's encouragement, she started transcribing the communications she received.

Over a period of seven decades, Schucman transcribed what might become A Course in Wonders, amounting to three sizes: the Text, the A Course In Miracles Workbook for Students, and the Handbook for Teachers. The Text sits out the theoretical basis of the program, elaborating on the primary concepts and principles. The Book for Students includes 365 lessons, one for every single time of the season, made to guide the reader through a everyday training of using the course's teachings. The Guide for Teachers provides further guidance on how best to understand and teach the rules of A Course in Wonders to others.

Among the central styles of A Class in Wonders is the notion of forgiveness. The course teaches that correct forgiveness is the key to inner peace and awareness to one's divine nature. In accordance with their teachings, forgiveness isn't only a moral or honest exercise but a essential change in perception. It involves letting move of judgments, grievances, and the perception of failure, and instead, seeing the entire world and oneself through the lens of enjoy and acceptance. A Course in Miracles highlights that true forgiveness results in the acceptance that we are all interconnected and that divorce from each other can be an illusion.

Still another significant part of A Program in Miracles is their metaphysical foundation. The course gifts a dualistic see of truth, unique between the vanity, which shows separation, anxiety, and illusions, and the Holy Nature, which symbolizes enjoy, reality, and religious guidance. It shows that the pride is the foundation of enduring and conflict, while the Holy Heart provides a pathway to healing and awakening. The goal of the course is to simply help people transcend the ego's confined perspective and align with the Sacred Spirit's guidance.
