The origins of A Program in Wonders can be traced back again to the collaboration between two persons, Helen Schucman and William Thetford, both of whom were distinguished psychologists and researchers. The course's inception occurred in early 1960s when Schucman, who had been a clinical and research psychologist at Columbia University's College of Physicians and Surgeons, began to see some inner dictations. She defined these dictations as via an inner voice that recognized it self as Jesus Christ. Schucman initially resisted these experiences, but with Thetford's support, she began transcribing the messages she received.

Around a period of seven decades, Schucman transcribed what would become A Program in Miracles, amounting to three sizes: the a course in miracles Text, the Workbook for Students, and the Guide for Teachers. The Text lays out the theoretical basis of the class, elaborating on the primary concepts and principles. The Workbook for Students includes 365 instructions, one for every day of the season, developed to guide the audience through a daily practice of using the course's teachings. The Information for Teachers offers more advice on how best to understand and show the axioms of A Course in Wonders to others.

One of the key themes of A Course in Miracles is the idea of forgiveness. The class teaches that correct forgiveness is the important thing to inner peace and awakening to one's divine nature. According to its teachings, forgiveness isn't simply a moral or honest exercise but a fundamental shift in perception. It requires letting move of judgments, issues, and the perception of sin, and alternatively, seeing the world and oneself through the lens of enjoy and acceptance. A Program in Miracles highlights that true forgiveness leads to the acceptance that individuals are interconnected and that separation from each other can be an illusion.

Still another significant aspect of A Program in Wonders is its metaphysical foundation. The program presents a dualistic view of reality, unique involving the confidence, which presents separation, anxiety, and illusions, and the Holy Spirit, which symbolizes love, reality, and spiritual guidance. It shows that the ego is the foundation of enduring and struggle, while the Sacred Nature offers a pathway to therapeutic and awakening. The goal of the program is to simply help persons transcend the ego's restricted perspective and align with the Holy Spirit's guidance.
