The beginnings of A Class in Wonders could be traced back again to the cooperation between two individuals, Helen Schucman and William Thetford, both of whom were outstanding psychologists and researchers. The course's inception occurred in the first 1960s when Schucman, who had been a scientific and study psychologist at Columbia University's University of Physicians and Surgeons, began to see some inner dictations. She identified these dictations as originating from an inner voice that discovered itself as Jesus Christ. Schucman initially resisted these experiences, but with Thetford's support, she started transcribing the messages she received.

Around an amount of seven a course in miracles podcasts, Schucman transcribed what can become A Class in Miracles, amounting to three quantities: the Text, the Book for Students, and the Information for Teachers. The Text lies out the theoretical foundation of the program, elaborating on the primary methods and principles. The Book for Pupils includes 365 classes, one for each day of the year, developed to steer the audience via a day-to-day exercise of using the course's teachings. The Handbook for Teachers offers more advice on how best to realize and show the rules of A Program in Wonders to others.

Among the central themes of A Class in Miracles is the idea of forgiveness. The course teaches that true forgiveness is the important thing to internal peace and awakening to one's heavenly nature. Based on their teachings, forgiveness is not only a moral or ethical practice but a basic change in perception. It involves allowing move of judgments, issues, and the belief of crime, and as an alternative, viewing the entire world and oneself through the lens of love and acceptance. A Course in Miracles stresses that correct forgiveness leads to the recognition that we are interconnected and that divorce from each other is an illusion.

Yet another significant facet of A Course in Wonders is their metaphysical foundation. The course gift suggestions a dualistic view of fact, distinguishing between the vanity, which represents divorce, fear, and illusions, and the Holy Nature, which symbolizes enjoy, reality, and spiritual guidance. It suggests that the pride is the origin of suffering and struggle, while the Holy Heart offers a pathway to therapeutic and awakening. The goal of the course is to simply help individuals surpass the ego's confined perception and arrange with the Sacred Spirit's guidance.
