The roots of A Program in Miracles could be followed back once again to the collaboration between two people, Helen Schucman and William Thetford, both of whom were distinguished psychologists and researchers. The course's inception happened in the early 1960s when Schucman, who was a scientific and research psychologist at Columbia University's College of Physicians and Surgeons, started to experience a series of internal dictations. She explained these dictations as via an interior voice that discovered it self as Jesus Christ. Schucman originally resisted these activities, but with Thetford's support, she started transcribing the messages she received.

Around a period of seven decades, Schucman transcribed what can become A Class in Miracles, amounting to three amounts: the Text, the Book for Pupils, a course in miracles and the Manual for Teachers. The Text lays out the theoretical base of the course, elaborating on the key methods and principles. The Workbook for Students contains 365 lessons, one for each time of the season, made to guide the audience by way of a daily exercise of applying the course's teachings. The Guide for Educators gives further guidance on the best way to realize and show the maxims of A Program in Miracles to others.

One of the central subjects of A Class in Wonders is the idea of forgiveness. The program teaches that true forgiveness is the important thing to inner peace and awakening to one's heavenly nature. In accordance with their teachings, forgiveness is not simply a moral or ethical practice but a fundamental change in perception. It involves making move of judgments, issues, and the notion of crime, and as an alternative, viewing the planet and oneself through the lens of love and acceptance. A Class in Miracles emphasizes that true forgiveness contributes to the recognition that we are typical interconnected and that separation from one another is an illusion.

Yet another significant facet of A Program in Wonders is its metaphysical foundation. The class gift suggestions a dualistic see of reality, distinguishing involving the confidence, which shows separation, concern, and illusions, and the Holy Heart, which symbolizes enjoy, reality, and religious guidance. It suggests that the pride is the origin of putting up with and conflict, as the Holy Soul provides a pathway to therapeutic and awakening. The goal of the program is to simply help individuals surpass the ego's limited perspective and align with the Sacred Spirit's guidance.
