The origins of A Class in Miracles can be followed back to the venture between two individuals, Helen Schucman and William Thetford, equally of whom were distinguished psychologists and researchers. The course's inception occurred in the early 1960s when Schucman, who had been a scientific and study psychologist at Columbia University's College of Physicians and Surgeons, started to experience some internal dictations. She identified these dictations as originating from an internal voice that discovered itself as Jesus Christ. Schucman originally resisted these activities, but with Thetford's encouragement, she began transcribing the messages she received.

Around a period of eight decades, Schucman transcribed what would become A Program in Wonders, amounting to three sizes: the Text, the Workbook for Pupils, and the Guide for Teachers. The Text lies out the theoretical base of the program, elaborating on the key  non dual teacher  methods and principles. The Book for Students contains 365 lessons, one for every single time of the year, developed to steer the audience by way of a everyday exercise of applying the course's teachings. The Manual for Teachers gives more advice on the best way to understand and show the axioms of A Class in Miracles to others.

One of the key themes of A Course in Wonders is the thought of forgiveness. The program teaches that true forgiveness is the main element to inner peace and awareness to one's heavenly nature. In accordance with their teachings, forgiveness is not only a moral or ethical exercise but a simple shift in perception. It involves letting get of judgments, issues, and the belief of failure, and alternatively, seeing the entire world and oneself through the lens of love and acceptance. A Class in Wonders highlights that correct forgiveness results in the recognition that individuals are all interconnected and that separation from one another can be an illusion.

Another substantial facet of A Course in Wonders is their metaphysical foundation. The program gift suggestions a dualistic see of fact, distinguishing between the confidence, which shows separation, anxiety, and illusions, and the Sacred Soul, which symbolizes enjoy, reality, and religious guidance. It implies that the vanity is the foundation of suffering and struggle, as the Holy Soul supplies a pathway to healing and awakening. The target of the program is to simply help people surpass the ego's limited perspective and align with the Sacred Spirit's guidance.
