The sources of A Course in Wonders may be followed back to the effort between two individuals, Helen Schucman and William Thetford, equally of whom were distinguished psychologists and researchers. The course's inception happened in early 1960s when Schucman, who was a medical and study psychologist at Columbia University's School of Physicians and Surgeons, started to experience some inner dictations. She defined these dictations as coming from an internal voice that identified it self as Jesus Christ. Schucman originally resisted these experiences, but with Thetford's encouragement, she started transcribing the messages she received.

Over a period of eight years, Schucman transcribed what would become A Class in Wonders, amounting to three volumes: the Text, the Book for Pupils, and the Manual for Teachers. The Text sits out the theoretical basis of the program, elaborating on the primary ideas and principles. The Workbook for Students contains 365 instructions, one for every single time of the season, made to guide the audience via a everyday practice of using the course's teachings. The Guide for Educators gives more advice on how best to understand and teach the concepts of A Program in Wonders to others.

One of many key themes of A Class in Miracles is the notion of forgiveness. The course teaches that true forgiveness is the key to internal peace and awareness to one's divine nature. Based on their teachings, forgiveness is not only a moral or david hoffmeister practice but a elementary shift in perception. It involves allowing get of judgments, issues, and the understanding of sin, and alternatively, seeing the world and oneself through the lens of love and acceptance. A Course in Miracles highlights that correct forgiveness results in the recognition that individuals are typical interconnected and that divorce from one another is an illusion.

It suggests that the ego is the source of putting up with and conflict, as the Sacred Soul supplies a pathway to healing and awakening. The goal of the class is to greatly help persons transcend the ego's restricted perception and align with the Sacred Spirit's guidance.
