The beginnings of A Class in Wonders can be tracked back to the relationship between two persons, Helen Schucman and Bill Thetford, both of whom were outstanding psychologists and researchers. The course's inception happened in early 1960s when Schucman, who had been a scientific and study psychologist at Columbia University's College of Physicians and Surgeons, started to have a series of internal dictations. She defined these dictations as coming from an interior style that recognized it self as Jesus Christ. Schucman originally resisted these activities, but with Thetford's support, she began transcribing the messages she received.

Around an amount of seven decades, Schucman transcribed what would become A Course in Wonders, amounting to three amounts: the Text, the Book for Pupils, and the Handbook for Teachers. The Text sits out the theoretical foundation of the course, elaborating on the jesus gospel of love  methods and principles. The Book for Pupils includes 365 classes, one for every single time of the season, made to guide the audience by way of a daily exercise of applying the course's teachings. The Guide for Teachers provides further guidance on the best way to realize and show the concepts of A Class in Miracles to others.

One of the key styles of A Program in Wonders is the idea of forgiveness. The class shows that true forgiveness is the main element to inner peace and awakening to one's heavenly nature. Based on its teachings, forgiveness is not only a ethical or moral practice but a fundamental shift in perception. It involves making go of judgments, issues, and the belief of crime, and as an alternative, seeing the world and oneself through the lens of enjoy and acceptance. A Class in Wonders highlights that correct forgiveness results in the acceptance that individuals are typical interconnected and that separation from each other is definitely an illusion.

Still another significant facet of A Class in Wonders is their metaphysical foundation. The class gift ideas a dualistic view of fact, distinguishing involving the pride, which represents separation, anxiety, and illusions, and the Sacred Heart, which symbolizes love, reality, and religious guidance. It implies that the confidence is the origin of suffering and struggle, whilst the Holy Nature offers a pathway to therapeutic and awakening. The target of the program is to help persons transcend the ego's limited perception and align with the Holy Spirit's guidance.
