The beginnings of A Course in Miracles could be tracked back again to the collaboration between two individuals, Helen Schucman and Bill Thetford, both of whom were prominent psychologists and researchers. The course's inception happened in the first 1960s when Schucman, who was a medical and study psychiatrist at Columbia University's School of Physicians and Surgeons, began to experience a series of inner dictations. She explained these dictations as coming from an interior voice that discovered it self as Jesus Christ. Schucman initially resisted these activities, but with Thetford's support, she began transcribing the messages she received.

Over an amount of eight years, Schucman transcribed what might become A Program in Wonders, amounting to three quantities: the Text, the Workbook for Pupils, and the Information for Teachers. The Text lies out the theoretical base of the course, elaborating on the primary ideas and principles. The Book for Students includes 365 instructions, one for each time of the entire year, acim to steer the reader via a daily exercise of applying the course's teachings. The Handbook for Teachers provides further guidance on how best to understand and show the axioms of A Class in Miracles to others.

Among the central themes of A Program in Wonders is the idea of forgiveness. The class shows that true forgiveness is the main element to inner peace and awareness to one's divine nature. According to their teachings, forgiveness isn't only a ethical or moral training but a simple change in perception. It involves allowing move of judgments, grievances, and the understanding of crime, and instead, seeing the world and oneself through the lens of love and acceptance. A Class in Miracles emphasizes that true forgiveness leads to the acceptance that people are interconnected and that divorce from each other is an illusion.

Still another substantial part of A Program in Miracles is its metaphysical foundation. The class presents a dualistic see of truth, unique involving the pride, which represents divorce, fear, and illusions, and the Holy Soul, which symbolizes love, truth, and spiritual guidance. It implies that the pride is the origin of putting up with and conflict, whilst the Sacred Heart supplies a pathway to therapeutic and awakening. The target of the class is to simply help people transcend the ego's restricted perception and arrange with the Holy Spirit's guidance.
