The roots of A Program in Wonders may be followed back to the venture between two people, Helen Schucman and William Thetford, equally of whom were prominent psychologists and researchers. The course's inception happened in the early 1960s when Schucman, who was a clinical and research psychiatrist at Columbia University's University of Physicians and Surgeons, started to experience a series of inner dictations. She explained these dictations as coming from an internal style that recognized itself as Jesus Christ. Schucman originally resisted these experiences, but with Thetford's encouragement, she started transcribing the communications she received.

Over a period of eight years, Schucman transcribed what would become A Class in Miracles, amounting to three volumes: the Text, the Workbook for Pupils, and the Guide for Teachers. The Text lies out the theoretical base of the program, elaborating on the core methods and the mystical teachings of Jesus . The Book for Students includes 365 instructions, one for every single day of the season, made to guide the audience through a everyday practice of applying the course's teachings. The Manual for Educators offers more advice on how to realize and train the principles of A Program in Wonders to others.

One of the main themes of A Class in Wonders is the notion of forgiveness. The course teaches that true forgiveness is the key to inner peace and awakening to one's heavenly nature. Based on their teachings, forgiveness is not simply a moral or moral exercise but a essential change in perception. It involves allowing go of judgments, issues, and the belief of crime, and instead, viewing the entire world and oneself through the contact of love and acceptance. A Course in Miracles highlights that true forgiveness leads to the acceptance that we are interconnected and that divorce from each other can be an illusion.

Yet another substantial part of A Course in Miracles is its metaphysical foundation. The course presents a dualistic view of reality, distinguishing involving the confidence, which shows divorce, concern, and illusions, and the Holy Spirit, which symbolizes love, reality, and spiritual guidance. It implies that the vanity is the foundation of putting up with and struggle, while the Sacred Nature supplies a pathway to therapeutic and awakening. The goal of the class is to greatly help persons transcend the ego's limited perception and arrange with the Holy Spirit's guidance.
