The sources of A Program in Miracles can be traced back to the cooperation between two persons, Helen Schucman and William Thetford, both of whom were distinguished psychologists and researchers. The course's inception occurred in the first 1960s when Schucman, who had been a clinical and research psychiatrist at Columbia University's School of Physicians and Surgeons, started to experience a series of internal dictations. She described these dictations as coming from an interior voice that discovered it self as Jesus Christ. Schucman originally resisted these activities, but with Thetford's support, she began transcribing the messages she received.

Around an amount of seven years, Schucman transcribed what can become A Course in a course in miracles , amounting to three sizes: the Text, the Workbook for Students, and the Information for Teachers. The Text lies out the theoretical basis of the course, elaborating on the primary methods and principles. The Workbook for Students includes 365 lessons, one for each time of the season, made to guide the reader by way of a everyday practice of using the course's teachings. The Guide for Educators gives more advice on the best way to realize and show the maxims of A Class in Miracles to others.

Among the key subjects of A Program in Wonders is the thought of forgiveness. The class shows that true forgiveness is the key to inner peace and awareness to one's divine nature. Based on its teachings, forgiveness is not simply a moral or ethical training but a basic shift in perception. It requires allowing go of judgments, grievances, and the belief of crime, and as an alternative, viewing the world and oneself through the lens of enjoy and acceptance. A Course in Miracles stresses that true forgiveness contributes to the acceptance that individuals are interconnected and that divorce from one another can be an illusion.

Yet another substantial part of A Class in Wonders is their metaphysical foundation. The class gifts a dualistic see of truth, unique involving the confidence, which represents divorce, anxiety, and illusions, and the Holy Spirit, which symbolizes love, reality, and religious guidance. It implies that the vanity is the origin of suffering and struggle, as the Holy Spirit supplies a pathway to healing and awakening. The target of the program is to simply help individuals transcend the ego's restricted perception and align with the Sacred Spirit's guidance.
