The sources of A Course in Wonders may be traced back again to the cooperation between two people, Helen Schucman and Bill Thetford, both of whom were outstanding psychologists and researchers. The course's inception happened in the early 1960s when Schucman, who had been a medical and research psychiatrist at Columbia University's College of Physicians and Surgeons, started to experience a series of internal dictations. She described these dictations as via an internal voice that discovered it self 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 years, Schucman transcribed what would become A Course in Miracles, amounting to three sizes: the Text, the Book for Students, and the Guide for Teachers. The Text lies out the theoretical basis of the class, elaborating on the key methods and  acim videos. The Workbook for Pupils includes 365 lessons, one for each day of the year, developed to steer the reader through a everyday exercise of applying the course's teachings. The Guide for Educators provides further guidance on how best to understand and show the maxims of A Class in Miracles 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 inner peace and awakening to one's divine nature. According to its teachings, forgiveness is not merely a ethical or moral training but a essential shift in perception. It involves making get of judgments, issues, and the belief of crime, and as an alternative, viewing the planet and oneself through the lens of enjoy and acceptance. A Class in Wonders stresses that true forgiveness leads to the acceptance that individuals are typical interconnected and that divorce from one another is definitely an illusion.

Yet another substantial facet of A Program in Wonders is its metaphysical foundation. The course gift ideas a dualistic view of reality, distinguishing between the pride, which represents divorce, fear, and illusions, and the Sacred Spirit, which symbolizes love, reality, and religious guidance. It implies that the vanity is the source of putting up with and conflict, while the Sacred Heart provides a pathway to therapeutic and awakening. The goal of the course is to simply help persons surpass the ego's restricted perception and align with the Holy Spirit's guidance.
