The beginnings of A Program in Wonders could be traced back to the cooperation between two individuals, Helen Schucman and William Thetford, equally of whom were prominent psychologists and researchers. The course's inception happened in early 1960s when Schucman, who had been a scientific and study psychologist at Columbia University's College of Physicians and Surgeons, started to experience a series of internal dictations. She defined these dictations as via an interior style that identified itself as Jesus Christ. Schucman originally resisted these experiences, but with Thetford's support, she started transcribing the communications she received.

Over an amount of seven years, Schucman transcribed what might become A Program in Wonders, amounting to three volumes: the Text, the Book for Students, and the Handbook for Teachers. The Text lays out the theoretical basis of the course, elaborating on the key ideas and principles. The Book for Students contains 365 lessons, one for every day of the entire year, developed to the christ steer the reader via a everyday practice of using the course's teachings. The Information for Teachers provides further guidance on the best way to realize and train the axioms of A Course in Miracles to others.

Among the main subjects of A Course in Wonders is the notion of forgiveness. The program shows that correct forgiveness is the key to internal peace and awareness to one's heavenly nature. According to their teachings, forgiveness is not only a ethical or moral exercise but a simple change in perception. It requires letting go of judgments, grievances, and the understanding of crime, and instead, seeing the world and oneself through the contact of enjoy and acceptance. A Course in Wonders highlights that true forgiveness leads to the recognition that we are all interconnected and that divorce from each other is an illusion.

Yet another substantial facet of A Program in Miracles is their metaphysical foundation. The class gifts a dualistic view of reality, distinguishing involving the ego, which presents separation, anxiety, and illusions, and the Holy Soul, which symbolizes enjoy, reality, and religious guidance. It implies that the pride is the source of enduring and struggle, while the Holy Soul offers a pathway to therapeutic and awakening. The target of the course is to greatly help people surpass the ego's confined perception and align with the Sacred Spirit's guidance.
