The sources of A Course in Wonders can be traced back to the effort between two individuals, Helen Schucman and William Thetford, equally of whom were prominent psychologists and researchers. The course's inception happened in the early 1960s when Schucman, who was simply a clinical and research psychologist at Columbia University's School of Physicians and Surgeons, started to see some inner dictations. She defined these dictations as coming from an internal style that determined it self as Jesus Christ. Schucman initially resisted these experiences, but with Thetford's inspiration, she started transcribing the communications she received.

Over a period of seven decades, Schucman transcribed what might become A Class in Miracles, amounting to three sizes: the Text, the Book for Students, and the Information for Teachers. The Text sits out the theoretical base of the class, elaborating on the core methods and acim podcast principles. The Book for Students contains 365 classes, one for every time of the season, developed to guide the reader via a daily exercise of using the course's teachings. The Information for Educators provides further guidance on the best way to understand and teach the rules of A Course in Wonders to others.

One of the central themes of A Course in Wonders is the idea of forgiveness. The class shows that correct forgiveness is the main element to inner peace and awareness to one's heavenly nature. According to its teachings, forgiveness is not only a ethical or honest practice but a basic change in perception. It involves making get of judgments, issues, and the notion of failure, and alternatively, viewing the world and oneself through the contact of enjoy and acceptance. A Course in Miracles highlights that true forgiveness contributes to the recognition that individuals are typical interconnected and that separation from each other is definitely an illusion.

Yet another substantial aspect of A Class in Miracles is their metaphysical foundation. The course presents a dualistic see of truth, unique involving the ego, which represents separation, anxiety, and illusions, and the Holy Spirit, which symbolizes love, truth, and religious guidance. It suggests that the pride is the source of suffering and conflict, while the Holy Spirit offers a pathway to therapeutic and awakening. The target of the program is to help persons surpass the ego's confined perception and arrange with the Holy Spirit's guidance.
