The sources of A Course in Miracles could be followed back to the venture between two individuals, Helen Schucman and William Thetford, both of whom were outstanding psychologists and researchers. The course's inception happened in the early 1960s when Schucman, who was simply a scientific and study psychologist at Columbia University's College of Physicians and Surgeons, began to see a series of inner dictations. She explained these dictations as coming from an internal voice that determined itself as Jesus Christ. Schucman originally resisted these experiences, but with Thetford's encouragement, she began transcribing the communications she received.

Over a period of seven decades, Schucman transcribed what can become A Class in Wonders, amounting to three amounts: the Text, the Workbook for Students, and the Guide for Teachers. The Text lays out the theoretical foundation of the class, elaborating on the primary acim and principles. The Book for Pupils includes 365 classes, one for every time of the entire year, developed to steer the audience by way of a everyday practice of applying the course's teachings. The Manual for Teachers gives more advice on how best to realize and show the axioms of A Class in Miracles to others.

One of the central subjects of A Program in Miracles is the idea of forgiveness. The program teaches that true forgiveness is the key to internal peace and awareness to one's heavenly nature. According to their teachings, forgiveness is not only a moral or moral exercise but a fundamental change in perception. It involves making get of judgments, issues, and the perception of crime, and instead, seeing the planet and oneself through the lens of enjoy and acceptance. A Course in Wonders highlights that true forgiveness contributes to the acceptance that people are typical interconnected and that divorce from each other is definitely an illusion.

Another substantial part of A Course in Miracles is its metaphysical foundation. The class gifts a dualistic see of truth, distinguishing between the confidence, which shows divorce, fear, and illusions, and the Sacred Spirit, which symbolizes love, reality, and spiritual guidance. It shows that the confidence is the source of putting up with and struggle, as the Holy Heart provides a pathway to therapeutic and awakening. The goal of the course is to greatly help persons surpass the ego's confined perception and arrange with the Holy Spirit's guidance.
