The origins of A Class in Miracles could be followed back to the relationship between two persons, Helen Schucman and Bill Thetford, both of whom were outstanding psychologists and researchers. The course's inception happened in the early 1960s when Schucman, who was a medical and research psychologist at Columbia University's College of Physicians and Surgeons, began to experience some inner dictations. She described these dictations as via an inner style that recognized it self as Jesus Christ. Schucman initially resisted these experiences, but with Thetford's support, she began transcribing the communications she received.

Over an amount of seven years, Schucman transcribed what would become A Course in Miracles, amounting to three volumes: the Text, the Workbook for Students, and the Guide for Teachers. The Text lays out the theoretical foundation of the course, elaborating on the key ideas and principles. The Workbook for Pupils includes 365 lessons, one for each day of the year, developed to steer the reader through a daily practice of using the course's teachings. The Manual for Teachers offers further guidance on how best to realize and train the principles of A Course in Miracles to others.

One of many key styles of A Program in Miracles is the notion of forgiveness. The course teaches that correct forgiveness is the main element to inner peace and awareness to one's heavenly nature. In accordance with their teachings, forgiveness isn't merely a ethical or honest training but a basic shift in perception. It requires letting get of judgments, grievances, and acim the perception of sin, and alternatively, viewing the world and oneself through the contact of love and acceptance. A Program in Wonders highlights that true forgiveness contributes to the recognition that people are interconnected and that divorce from one another is definitely an illusion.

Yet another substantial facet of A Class in Miracles is their metaphysical foundation. The course presents a dualistic view of truth, unique involving the confidence, which represents separation, anxiety, and illusions, and the Holy Spirit, which symbolizes love, reality, and spiritual guidance. It implies that the vanity is the foundation of suffering and struggle, while the Holy Soul provides a pathway to therapeutic and awakening. The goal of the class is to help people transcend the ego's restricted perception and arrange with the Sacred Spirit's guidance.
