The sources of A Class in Miracles could be followed back once again to the relationship between two persons, Helen Schucman and William Thetford, both of whom were distinguished psychologists and researchers. The course's inception happened in the first 1960s when Schucman, who had been a clinical and study psychiatrist at Columbia University's University of Physicians and Surgeons, began to experience some inner dictations. She defined these dictations as via an inner style that recognized itself as Jesus Christ. Schucman initially resisted these experiences, but with Thetford's support, she started transcribing the communications she received.

Over a period of seven years, Schucman transcribed what can become A Class in Miracles, amounting to three amounts: the Text, the Book for Students, and the Information for Teachers. The acim Text lies out the theoretical foundation of the class, elaborating on the primary ideas and principles. The Book for Students contains 365 lessons, one for each day of the entire year, developed to guide the reader by way of a daily training of applying the course's teachings. The Information for Teachers provides more guidance on the best way to realize and teach the rules of A Course in Wonders to others.

One of many key subjects of A Class in Wonders is the thought of forgiveness. The course teaches that correct forgiveness is the key to inner peace and awareness to one's heavenly nature. Based on its teachings, forgiveness isn't only a ethical or moral practice but a essential change in perception. It requires letting go of judgments, issues, and the understanding of crime, and instead, viewing the entire world and oneself through the lens of love and acceptance. A Course in Wonders highlights that correct forgiveness contributes to the recognition that people are interconnected and that divorce from each other is definitely an illusion.

Yet another substantial part of A Course in Wonders is its metaphysical foundation. The class gift suggestions a dualistic view of truth, distinguishing between the vanity, which presents separation, fear, and illusions, and the Holy Soul, which symbolizes love, reality, and religious guidance. It shows that the vanity is the foundation of enduring and struggle, while the Holy Nature provides a pathway to therapeutic and awakening. The goal of the class is to simply help persons transcend the ego's limited perception and align with the Holy Spirit's guidance.
