The sources of A Class in Wonders may be tracked back once again to the venture between two persons, Helen Schucman and William Thetford, both of whom were distinguished psychologists and researchers. The course's inception occurred in the early 1960s when Schucman, who was a scientific and research psychologist at Columbia University's University of Physicians and Surgeons, started to have a series of internal dictations. She described these dictations as via an inner voice that recognized itself as Jesus Christ. Schucman originally resisted these activities, but with Thetford's encouragement, she began transcribing the messages she received.

Over a period of eight years, Schucman transcribed what might become A Course in Miracles, amounting to three amounts: the Text, the Workbook for Students, and the Information for Teachers. The Text lies out the theoretical foundation of the program, elaborating on the core concepts and principles. The Book for Students contains 365 lessons, one for each time of the season, developed to guide the reader via a everyday practice of using the course's teachings. The Information for Teachers offers more guidance on how to realize and teach the axioms of A Course in Wonders to others.

Among the central styles of A Class in Wonders is the idea of forgiveness. The program shows that correct forgiveness is the main element to internal peace and awareness to one's divine nature. According to its teachings, a course in miracles isn't simply a ethical or ethical practice but a elementary shift in perception. It requires allowing move of judgments, grievances, and the notion of failure, and instead, seeing the entire world and oneself through the lens of love and acceptance. A Class in Wonders stresses that true forgiveness leads to the acceptance that we are interconnected and that divorce from one another can be an illusion.

Yet another significant part of A Program in Wonders is their metaphysical foundation. The class gifts a dualistic view of reality, unique involving the confidence, which represents separation, concern, and illusions, and the Sacred Spirit, which symbolizes love, reality, and spiritual guidance. It implies that the pride is the origin of putting up with and struggle, while the Sacred Heart provides a pathway to therapeutic and awakening. The target of the course is to simply help people transcend the ego's restricted perception and arrange with the Holy Spirit's guidance.
