The sources of A Class in Miracles may be tracked back once again to the collaboration between two people, Helen Schucman and William Thetford, equally of whom were prominent psychologists and researchers. The course's inception happened in the first 1960s when Schucman, who was simply a medical and research psychologist at Columbia University's University of Physicians and Surgeons, started to have a series of internal dictations. She described these dictations as via an interior voice that discovered itself as Jesus Christ. Schucman initially resisted these activities, but with Thetford's support, she began transcribing the messages she received.

Over a period of eight decades, Schucman transcribed what would become A Class in Miracles, amounting to three amounts: the Text, the Book for Students, and the Guide for Teachers. The Text lies out the theoretical foundation of the class, elaborating on the key methods and acim teachers . The Workbook for Students includes 365 lessons, one for every time of the season, developed to guide the reader by way of a day-to-day training of applying the course's teachings. The Manual for Educators gives more advice on how best to realize and teach the axioms of A Course in Wonders to others.

One of the key themes of A Program in Miracles is the notion of forgiveness. The class teaches that true forgiveness is the main element to inner peace and awakening to one's divine nature. According to its teachings, forgiveness is not merely a ethical or honest training but a essential shift in perception. It requires letting move of judgments, grievances, and the belief of crime, and alternatively, viewing the entire world and oneself through the contact of enjoy and acceptance. A Class in Wonders stresses that true forgiveness leads to the acceptance that we are typical interconnected and that separation from each other can be an illusion.

Another significant part of A Course in Miracles is its metaphysical foundation. The class gift ideas a dualistic view of reality, unique between the vanity, which shows divorce, fear, and illusions, and the Holy Heart, which symbolizes love, reality, and religious guidance. It shows that the vanity is the origin of putting up with and conflict, as the Sacred Soul offers a pathway to therapeutic and awakening. The goal of the class is to greatly help people transcend the ego's confined perspective and align with the Sacred Spirit's guidance.
