Around a period of eight decades, Schucman transcribed what would become A Program in Wonders, amounting to three amounts: the Text, the Workbook for Students, and the Guide for Teachers. The Text lies out the theoretical foundation of the class, elaborating on the key ideas and principles. The Book for Pupils contains 365 classes, one for each time of the entire year, made to steer the reader through a daily practice of using the course's teachings. The Manual for Teachers offers more guidance on the best way to understand and train the axioms of A Course in Miracles to others.

One of the central themes of A Course in Miracles is the thought of forgiveness. The program shows that true forgiveness is the key to internal peace and awareness to one's heavenly nature. According to their teachings, forgiveness isn't only a  ethical or moral exercise but a essential change in perception. It requires making move of judgments, issues, a course in miracles and the notion of crime, and alternatively, seeing the planet and oneself through the lens of enjoy and acceptance. A Class in Miracles highlights that correct forgiveness contributes to the recognition that individuals are interconnected and that separation from one another is an illusion.

Still another substantial part of A Program in Wonders is its metaphysical foundation. The class gift ideas a dualistic view of reality, unique involving the pride, which presents separation, concern, and illusions, and the Holy Soul, which symbolizes love, truth, and religious guidance. It shows that the pride is the source of enduring and struggle, as the Holy Soul offers a pathway to healing and awakening. The target of the class is to simply help persons transcend the ego's limited perspective and arrange with the Sacred Spirit's guidance.

A Program in Wonders also presents the idea of wonders, which are understood as adjustments in perception that come from a place of enjoy and forgiveness. Miracles, in that situation, aren't supernatural activities but alternatively activities where people see the truth in somebody beyond their pride and limitations. These activities can be equally particular and cultural, as people come to appreciate their heavenly character and the heavenly nature of others. Wonders are viewed as the natural outcome of practicing the course's teachings.
