The roots of A Program in Miracles may be tracked back once again to the cooperation between two individuals, Helen Schucman and Bill Thetford, both of whom were prominent psychologists and researchers. The course's inception happened in early 1960s when Schucman, who was simply a scientific and study psychiatrist at Columbia University's University of Physicians and Surgeons, started to experience a series of inner dictations. She described these dictations as originating from an interior style that recognized it self as Jesus Christ. Schucman initially resisted these experiences, but with Thetford's support, she started transcribing the messages she received.

Around a period of eight decades, Schucman transcribed what can become A Course in Wonders, amounting to three sizes: the Text, the Workbook for Students, and the Manual for Teachers. The Text sits out the theoretical base of the program, elaborating acim on the key concepts and principles. The Book for Students contains 365 lessons, one for each time of the season, made to guide the reader through a daily exercise of applying the course's teachings. The Guide for Teachers provides more guidance on how to understand and train the principles of A Program in Miracles to others.

Among the main themes of A Class in Miracles is the notion of forgiveness. The program shows that correct forgiveness is the important thing to inner peace and awakening to one's divine nature. In accordance with its teachings, forgiveness is not merely a moral or ethical exercise but a essential shift in perception. It requires making move of judgments, grievances, and the perception of failure, and as an alternative, seeing the entire world and oneself through the contact of love and acceptance. A Class in Wonders stresses that true forgiveness contributes to the acceptance that individuals are interconnected and that divorce from each other can be an illusion.

Still another significant part of A Program in Wonders is its metaphysical foundation. The class gifts a dualistic see of truth, unique involving the ego, which presents separation, anxiety, and illusions, and the Sacred Spirit, which symbolizes enjoy, truth, and spiritual guidance. It shows that the pride is the source of enduring and struggle, while the Holy Spirit provides a pathway to healing and awakening. The target of the course is to greatly help people transcend the ego's confined perspective and align with the Holy Spirit's guidance.
