The origins of A Program in Miracles can be traced back to the effort between two individuals, Helen Schucman and William Thetford, equally of whom were outstanding psychologists and researchers. The course's inception happened in the early 1960s when Schucman, who was a scientific and study psychiatrist at Columbia University's School of Physicians and Surgeons, began to see some inner dictations. She described these dictations as originating from an inner voice that discovered it self as Jesus Christ. Schucman originally resisted these activities, but with Thetford's support, she began transcribing the messages she received.

Over a period of seven decades, Schucman transcribed what would become A Course in Miracles, amounting to three sizes: the Text, the Book for Pupils, and the Handbook for Teachers. The Text lays out the theoretical foundation of the class, elaborating on the core methods and principles. The Workbook for Pupils contains 365 instructions, one for each time of the year, developed to guide the audience by way of a daily training of using the course's teachings. The Information for Educators provides more advice on how best to realize and show the maxims of A Program in Wonders to others.

One of many central themes of A Class in Miracles is the notion of forgiveness. The class teaches that correct forgiveness is the key to internal peace and awareness to one's divine nature. In accordance with its teachings, forgiveness is not merely a moral or ethical training but a elementary change in perception. It requires making go of judgments,  a course in miracles , and the belief of sin, and alternatively, seeing the world and oneself through the contact of love and acceptance. A Course in Wonders highlights that true forgiveness results in the recognition that individuals are typical interconnected and that divorce from one another can be an illusion.

Still another substantial part of A Course in Miracles is their metaphysical foundation. The program presents a dualistic view of truth, distinguishing involving the vanity, which presents separation, fear, and illusions, and the Holy Spirit, which symbolizes love, reality, and spiritual guidance. It suggests that the pride is the origin of putting up with and struggle, whilst the Sacred Spirit provides a pathway to therapeutic and awakening. The goal of the course is to greatly help individuals transcend the ego's confined perspective and align with the Holy Spirit's guidance.
