The beginnings of A Course in Wonders could be followed back again to the collaboration between two individuals, Helen Schucman and Bill Thetford, equally of whom were prominent psychologists and researchers. The course's inception occurred in the first 1960s when Schucman, who was simply a scientific and study psychologist at Columbia University's University of Physicians and Surgeons, started to experience some internal dictations. She defined these dictations as originating from an interior voice that recognized itself as Jesus Christ. Schucman initially resisted these activities, but with Thetford's encouragement, she started transcribing the messages she received.

Around a period of seven decades, Schucman transcribed what would become A Class in Wonders, amounting to three quantities: the Text, the Book for Students, and the Manual for Teachers. The Text lays out the theoretical base of the class, elaborating on the key concepts and principles. The Workbook for Students contains 365 lessons, one for each day of the year, developed to steer the reader through a everyday practice of using the course's teachings. The Manual for Educators gives more advice on the best way to realize and show the concepts of A Course in Miracles to others.

Among the main subjects of A Program in Wonders is the idea of forgiveness. The class teaches that true forgiveness is the main element to inner peace and awareness to one's divine nature. Based on its teachings,  a course in miracles  is not only a ethical or ethical exercise but a basic change in perception. It involves making go of judgments, grievances, and the understanding of crime, and alternatively, viewing the planet and oneself through the contact of enjoy and acceptance. A Class in Wonders highlights that correct forgiveness leads to the acceptance that we are all interconnected and that divorce from one another is definitely an illusion.

Another significant aspect of A Course in Miracles is its metaphysical foundation. The course gift suggestions a dualistic see of truth, distinguishing involving the ego, which represents separation, fear, and illusions, and the Sacred Nature, which symbolizes enjoy, truth, and religious guidance. It implies that the ego is the origin of putting up with and struggle, while the Sacred Heart offers a pathway to therapeutic and awakening. The goal of the course is to greatly help persons transcend the ego's confined perception and arrange with the Holy Spirit's guidance.
