The roots of A Program in Miracles could be tracked back to the relationship between two individuals, Helen Schucman and William Thetford, both of whom were prominent psychologists and researchers. The course's inception happened in early 1960s when Schucman, who was a scientific and research psychologist at Columbia University's School of Physicians and Surgeons, started to have a series of internal dictations. She defined these dictations as originating from an interior style that identified itself as Jesus Christ. Schucman originally resisted these experiences, but with Thetford's encouragement, she started transcribing the communications she received.

Around a period of seven decades, Schucman transcribed what might become A Class in Wonders, amounting to three amounts: the Text, the Workbook for Pupils, and the Guide for Teachers. The Text sits out the acim book theoretical base of the class, elaborating on the primary methods and principles. The Book for Students contains 365 instructions, one for every single time of the season, developed to guide the audience via a daily exercise of applying the course's teachings. The Information for Teachers gives further advice on how best to realize and teach the principles of A Class in Wonders to others.

One of many central styles of A Class in Wonders is the notion of forgiveness. The class teaches that true forgiveness is the key to inner peace and awakening to one's divine nature. According to their teachings, forgiveness is not only a ethical or moral practice but a basic change in perception. It involves letting move of judgments, grievances, and the notion of sin, and as an alternative, viewing the entire world and oneself through the lens of love and acceptance. A Program in Wonders stresses that correct forgiveness leads to the recognition that we are typical interconnected and that separation from each other is definitely an illusion.

Still another significant part of A Class in Miracles is its metaphysical foundation. The program gift suggestions a dualistic view of reality, distinguishing involving the vanity, which represents separation, fear, and illusions, and the Sacred Spirit, which symbolizes love, truth, and religious guidance. It suggests that the pride is the origin of enduring and conflict, while the Sacred Spirit provides a pathway to healing and awakening. The target of the program is to help individuals transcend the ego's limited perspective and arrange with the Sacred Spirit's guidance.
