The beginnings of A Course in Wonders may be followed back to the venture between two individuals, Helen Schucman and William Thetford, equally of whom were distinguished psychologists and researchers. The course's inception happened in the first 1960s when Schucman, who had been a medical and study psychiatrist at Columbia University's College of Physicians and Surgeons, began to have some internal dictations. She described these dictations as originating from an inner voice that recognized it self as Jesus Christ. Schucman initially resisted these experiences, but with Thetford's support, she started transcribing the messages she received.

Over a period of seven years, Schucman transcribed what would become A Program in Wonders, amounting to three volumes: the Text, the Book for Students, and the Guide for Teachers. The Text lies out the theoretical base of the course, elaborating on the core methods and principles. The Book for Pupils includes 365 a course in miracles lessons, one for each day of the entire year, designed to steer the reader through a everyday practice of using the course's teachings. The Handbook for Educators offers more advice on how to realize and train the rules of A Program in Wonders to others.

One of the main subjects of A Course in Miracles is the idea of forgiveness. The class teaches that true forgiveness is the key to inner peace and awakening to one's heavenly nature. Based on their teachings, forgiveness isn't simply a moral or honest exercise but a elementary shift in perception. It involves letting get of judgments, grievances, and the belief of crime, and alternatively, viewing the entire world and oneself through the lens of enjoy and acceptance. A Course in Wonders emphasizes that true forgiveness leads to the recognition that we are interconnected and that divorce from each other can be an illusion.

Yet another substantial part of A Course in Miracles is their metaphysical foundation. The class gifts a dualistic view of reality, unique involving the confidence, which represents separation, concern, and illusions, and the Holy Nature, which symbolizes love, reality, and religious guidance. It shows that the ego is the origin of putting up with and conflict, while the Holy Nature offers a pathway to therapeutic and awakening. The goal of the class is to help individuals surpass the ego's restricted perspective and align with the Sacred Spirit's guidance.
