The sources of A Class in Wonders may be tracked back to the relationship between two individuals, Helen Schucman and Bill Thetford, equally of whom were prominent psychologists and researchers. The course's inception occurred in the early 1960s when Schucman, who was simply a clinical and research psychologist at Columbia University's College of Physicians and Surgeons, began to have some internal dictations. She described these dictations as originating from an internal style that determined itself as Jesus Christ. Schucman initially resisted these activities, but with Thetford's inspiration, she began transcribing the messages she received.

Over a period of eight decades, Schucman transcribed what can become A Program in Miracles, amounting to three amounts: the Text, the Book for Pupils, and the Guide for Teachers. The Text sits out the theoretical foundation of the acim online course, elaborating on the core concepts and principles. The Workbook for Pupils contains 365 lessons, one for every day of the entire year, made to guide the audience via a day-to-day training of using the course's teachings. The Manual for Teachers offers further guidance on how to understand and show the principles of A Course in Miracles to others.

Among the key themes of A Program in Miracles is the idea of forgiveness. The program teaches that true forgiveness is the main element to inner peace and awakening to one's divine nature. Based on its teachings, forgiveness isn't simply a ethical or honest training but a essential shift in perception. It involves allowing go of judgments, issues, and the perception of sin, and as an alternative, seeing the world and oneself through the lens of enjoy and acceptance. A Course in Miracles stresses that true forgiveness results in the acceptance that we are all interconnected and that divorce from each other can be an illusion.

Yet another significant facet of A Class in Miracles is their metaphysical foundation. The course gift ideas a dualistic view of fact, unique between the vanity, which shows separation, anxiety, and illusions, and the Holy Nature, which symbolizes enjoy, truth, and spiritual guidance. It implies that the ego is the origin of putting up with and struggle, while the Holy Soul supplies a pathway to therapeutic and awakening. The goal of the course is to greatly help persons surpass the ego's limited perspective and align with the Holy Spirit's guidance.
