The origins of A Program in Wonders can be followed back once again to the relationship between two persons, Helen Schucman and Bill Thetford, both of whom were distinguished psychologists and researchers. The course's inception happened in early 1960s when Schucman, who was simply a scientific and research psychiatrist at Columbia University's University of Physicians and Surgeons, started to see some internal dictations. She identified these dictations as via an interior style that determined it self as Jesus Christ. Schucman initially resisted these activities, but with Thetford's inspiration, she began transcribing the messages she received.

Around an amount of eight decades, Schucman transcribed what would become A Course in Wonders, amounting to three sizes: the Text, the Workbook for Students, and the Guide for Teachers. The Text lies out the theoretical ACIM basis of the course, elaborating on the primary methods and principles. The Workbook for Pupils contains 365 instructions, one for every day of the season, designed to guide the audience through a daily training of applying the course's teachings. The Handbook for Educators provides more guidance on how to understand and show the rules of A Program in Miracles to others.

One of the key styles of A Course in Wonders is the thought of forgiveness. The class shows that correct forgiveness is the main element to inner peace and awareness to one's divine nature. Based on their teachings, forgiveness is not simply a moral or ethical exercise but a basic shift in perception. It requires letting go of judgments, grievances, and the notion of crime, and instead, seeing the planet and oneself through the contact of love and acceptance. A Program in Wonders stresses that correct forgiveness contributes to the recognition that we are all interconnected and that separation from each other is an illusion.

Another significant part of A Program in Wonders is their metaphysical foundation. The class gift ideas a dualistic view of fact, unique between the vanity, which shows divorce, anxiety, and illusions, and the Holy Soul, which symbolizes enjoy, truth, and spiritual guidance. It implies that the vanity is the foundation of putting up with and struggle, while the Holy Spirit provides a pathway to healing and awakening. The target of the class is to help people transcend the ego's limited perception and arrange with the Holy Spirit's guidance.
