The sources of A Class in Wonders can be tracked back to the relationship 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 medical and study psychiatrist at Columbia University's University of Physicians and Surgeons, began to experience some internal dictations. She defined these dictations as via an interior style that identified it self as Jesus Christ. Schucman initially resisted these activities, but with Thetford's inspiration, she began transcribing the communications she received.

Around a period of eight decades, Schucman transcribed what can become A Course in Miracles, amounting to three amounts: the Text, the Book for Students, and the Information for Teachers. The Text sits out the theoretical basis of the program, elaborating on the key methods and principles. The Workbook for Students includes 365 lessons, one for every single day of the season, a course in miracles  to guide the audience via a daily practice of using the course's teachings. The Manual for Teachers provides more guidance on how best to understand and show the concepts of A Program in Wonders to others.

One of the main styles of A Class in Wonders is the idea of forgiveness. The course shows that true forgiveness is the important thing to internal peace and awakening to one's divine nature. According to their teachings, forgiveness isn't simply a ethical or ethical exercise but a basic shift in perception. It involves letting get of judgments, issues, and the perception of crime, and instead, seeing the world and oneself through the contact of enjoy and acceptance. A Course in Wonders highlights that correct forgiveness results in the acceptance that individuals are interconnected and that separation from one another is an illusion.

Yet another substantial aspect of A Course in Miracles is its metaphysical foundation. The course gifts a dualistic see of fact, unique between the vanity, which represents divorce, fear, and illusions, and the Sacred Nature, which symbolizes love, reality, and religious guidance. It suggests that the pride is the foundation of enduring and struggle, as the Sacred Nature offers a pathway to healing and awakening. The goal of the class is to greatly help persons transcend the ego's confined perspective and align with the Sacred Spirit's guidance.
