The sources of A Program in Wonders can be tracked back to the relationship between two persons, Helen Schucman and William Thetford, both of whom were outstanding psychologists and researchers. The course's inception occurred in the early 1960s when Schucman, who was a scientific and research psychologist at Columbia University's University of Physicians and Surgeons, started to experience a series of inner dictations. She defined these dictations as via an interior voice that determined it self as Jesus Christ. Schucman initially resisted these activities, but with Thetford's encouragement, she began transcribing the communications she received.

Around a period of eight years, Schucman transcribed what might become A Class in Miracles, amounting to three quantities: the Text, the Book for Pupils, and the Manual for Teachers. The Text sits out the theoretical foundation of the course, elaborating on the core ideas and principles. The Workbook  a course in miracles  for Pupils includes 365 lessons, one for every time of the entire year, developed to guide the reader through a everyday exercise of applying the course's teachings. The Guide for Teachers offers more advice on how best to understand and show the axioms of A Course in Miracles to others.

One of the central subjects of A Class in Miracles is the idea of forgiveness. The course teaches that correct forgiveness is the main element to internal peace and awakening to one's heavenly nature. Based on their teachings, forgiveness is not simply a moral or moral training but a elementary shift in perception. It requires allowing move of judgments, grievances, and the notion of failure, and as an alternative, viewing the planet and oneself through the contact of love and acceptance. A Course in Wonders highlights that correct forgiveness results in the recognition that individuals are interconnected and that divorce from one another is definitely an illusion.

Yet another substantial facet of A Course in Wonders is its metaphysical foundation. The program gifts a dualistic see of reality, distinguishing between the vanity, which represents separation, anxiety, and illusions, and the Holy Nature, which symbolizes love, reality, and spiritual guidance. It suggests that the vanity is the origin of suffering and struggle, whilst the Holy Nature provides a pathway to healing and awakening. The goal of the program is to help individuals transcend the ego's confined perception and arrange with the Holy Spirit's guidance.
