The origins of A Course in Miracles could be traced back to the relationship between two people, Helen Schucman and Bill Thetford, both of whom were prominent psychologists and researchers. The course's inception happened in the first 1960s when Schucman, who had been a medical and study psychologist at Columbia University's University of Physicians and Surgeons, started to have some internal dictations. She identified these dictations as coming from an interior voice that discovered it self as Jesus Christ. Schucman initially resisted these activities, but with Thetford's inspiration, she began transcribing the messages she received.

Around a period of eight years, Schucman transcribed what can become A Program in Wonders, amounting to three sizes: the Text, the Book for Pupils, and the Information for Teachers. The Text lays out the theoretical base of the class, elaborating on the core acim and principles. The Book for Students contains 365 lessons, one for every time of the season, made to guide the reader through a daily practice of applying the course's teachings. The Manual for Educators offers more advice on how to realize and show the axioms of A Course in Miracles to others.

One of the central themes of A Class in Wonders is the thought of forgiveness. The program teaches that true forgiveness is the important thing to internal peace and awakening to one's heavenly nature. In accordance with its teachings, forgiveness is not merely a ethical or moral training but a elementary shift in perception. It involves making move of judgments, grievances, and the understanding of failure, and alternatively, viewing the planet and oneself through the lens of enjoy and acceptance. A Course in Miracles highlights that correct forgiveness leads to the recognition that people are typical interconnected and that separation from one another can be an illusion.

Another substantial facet of A Class in Wonders is its metaphysical foundation. The course gift ideas a dualistic see of reality, distinguishing involving the vanity, which shows separation, fear, and illusions, and the Holy Heart, which symbolizes enjoy, reality, and spiritual guidance. It implies that the pride is the origin of putting up with and conflict, as the Holy Spirit offers a pathway to therapeutic and awakening. The goal of the class is to simply help persons transcend the ego's confined perspective and arrange with the Sacred Spirit's guidance.
