The origins of A Program in Wonders can be tracked back once again to the collaboration between two persons, Helen Schucman and William Thetford, both of whom were prominent psychologists and researchers. The course's inception happened in the first 1960s when Schucman, who was simply a medical and study psychologist at Columbia University's School of Physicians and Surgeons, started to have some inner dictations. She described these dictations as originating from an inner voice that identified itself as Jesus Christ. Schucman originally resisted these experiences, but with Thetford's inspiration, she started transcribing the communications she received.

Around a period of seven years, Schucman transcribed what can become A Class in Miracles, amounting to three sizes: the Text, the Book for Students, and the Handbook for Teachers. The Text acim sits out the theoretical base of the program, elaborating on the core concepts and  principles. The Book for Students contains 365 classes, one for every single time of the season, made to guide the reader by way of a day-to-day training of applying the course's teachings. The Manual for Teachers gives further advice on the best way to realize and teach the principles of A Program in Wonders to others.

One of many central subjects of A Class in Wonders is the idea of forgiveness. The class teaches that true forgiveness is the important thing to inner peace and awakening to one's heavenly nature. Based on their teachings, forgiveness is not only a moral or moral practice but a fundamental change in perception. It involves letting move of judgments, grievances, and the understanding of sin, and as an alternative, seeing the entire world and oneself through the contact of enjoy and acceptance. A Program in Miracles emphasizes that true forgiveness contributes to the recognition that people are all interconnected and that separation from each other is definitely an illusion.

Another significant aspect of A Course in Wonders is its metaphysical foundation. The course gift ideas a dualistic view of reality, unique between the vanity, which represents divorce, fear, and illusions, and the Holy Nature, which symbolizes love, reality, and spiritual guidance. It suggests that the confidence is the origin of suffering and struggle, as the Sacred Heart supplies a pathway to therapeutic and awakening. The target of the class is to help people transcend the ego's restricted perspective and arrange with the Sacred Spirit's guidance.
