The sources of A Course in Miracles can be tracked back to the venture between two people, Helen Schucman and William Thetford, both of whom were distinguished psychologists and researchers. The course's inception happened in the early 1960s when Schucman, who was simply a medical and study psychologist at Columbia University's University of Physicians and Surgeons, began to see a series of internal dictations. She defined these dictations as coming from an inner voice that determined it self as Jesus Christ. Schucman originally resisted these experiences, but with Thetford's support, she started transcribing the messages she received.

Over an amount of seven decades, Schucman transcribed what can become A Course in Miracles, amounting to three amounts: the Text, the Workbook for Students, and the Information for Teachers. The Text sits out the theoretical a course in miracles online basis of the program, elaborating on the primary methods and principles. The Book for Pupils includes 365 classes, one for every day of the entire year, designed to steer the audience by way of a day-to-day exercise of applying the course's teachings. The Information for Teachers offers further guidance on the best way to understand and show the principles of A Course in Miracles to others.

One of the main subjects of A Class in Wonders is the idea of forgiveness. The program teaches that correct forgiveness is the main element to inner peace and awakening to one's heavenly nature. In accordance with their teachings, forgiveness is not simply a moral or honest training but a elementary shift in perception. It involves allowing move of judgments, issues, and the notion of failure, and instead, seeing the world and oneself through the lens of love and acceptance. A Class in Miracles emphasizes that correct forgiveness leads to the recognition that individuals are all interconnected and that divorce from each other can be an illusion.

Yet another substantial aspect of A Program in Wonders is its metaphysical foundation. The course presents a dualistic view of fact, distinguishing between the ego, which presents divorce, fear, and illusions, and the Holy Spirit, which symbolizes love, truth, and spiritual guidance. It suggests that the confidence is the origin of suffering and conflict, as the Holy Heart provides a pathway to therapeutic and awakening. The target of the class is to simply help people transcend the ego's restricted perspective and align with the Holy Spirit's guidance.
