The beginnings of A Class in Miracles can be tracked back again to the effort between two persons, Helen Schucman and Bill Thetford, both of whom were prominent psychologists and researchers. The course's inception occurred in the first 1960s when Schucman, who was a medical and study psychologist at Columbia University's College of Physicians and Surgeons, started to experience some internal dictations. She described these dictations as originating from an inner voice that discovered itself as Jesus Christ. Schucman originally resisted these experiences, but with Thetford's support, she began transcribing the messages she received.

Over an amount of eight years, Schucman transcribed what can become A Course in Wonders, amounting to three sizes: the Text, the Book for Pupils, and a course in miracles the Handbook for Teachers. The Text sits out the theoretical foundation of the program, elaborating on the primary ideas and principles. The Book for Pupils includes 365 lessons, one for every single time of the season, developed to guide the reader through a everyday training of using the course's teachings. The Guide for Teachers offers further guidance on the best way to realize and show the axioms of A Class in Miracles to others.

One of many key subjects of A Class in Wonders is the idea of forgiveness. The class teaches that correct forgiveness is the important thing to inner peace and awakening to one's divine nature. According to its teachings, forgiveness is not only a moral or honest exercise but a basic change in perception. It involves letting move of judgments, issues, and the understanding of sin, and alternatively, viewing the planet and oneself through the lens of enjoy and acceptance. A Program in Wonders stresses that correct forgiveness contributes to the acceptance that we are interconnected and that separation from one another is definitely an illusion.

Another significant facet of A Program in Wonders is its metaphysical foundation. The class presents a dualistic see of truth, distinguishing between the confidence, which represents divorce, concern, and illusions, and the Holy Nature, which symbolizes love, reality, and religious guidance. It shows that the ego is the source of suffering and conflict, as the Holy Soul offers a pathway to therapeutic and awakening. The goal of the class is to help people surpass the ego's restricted perception and align with the Holy Spirit's guidance.
