Over an amount of seven decades, Schucman transcribed what would become A Program in Miracles, amounting to three amounts: the Text, the Workbook for Pupils, and the Guide for Teachers. The Text lies out the theoretical basis of the program, elaborating on the key ideas and principles. The Workbook for Students contains 365 instructions, one for each day of the season, developed to guide the audience via a everyday training of using the course's teachings. The Manual for Educators gives more advice on how to understand and teach the concepts of A Course in Miracles to others.

One of the main themes of A Class in Miracles is the idea of forgiveness. The course shows that true forgiveness is the main element to inner peace and awakening to one's divine nature. In accordance with its teachings, forgiveness is not simply a ethical or honest jesus gospel of love but a basic shift in perception. It requires making move of judgments, grievances, and the notion of failure, and instead, seeing the entire world and oneself through the contact of enjoy and acceptance. A Program in Wonders emphasizes that true forgiveness results in the recognition that we are all interconnected and that separation from each other is definitely an illusion.

Another significant part of A Class in Wonders is its metaphysical foundation. The program presents a dualistic see of reality, unique involving the pride, which represents separation, fear, and illusions, and the Sacred Heart, which symbolizes love, truth, and religious guidance. It implies that the vanity is the foundation of putting up with and conflict, as the Sacred Spirit provides a pathway to healing and awakening. The goal of the program is to simply help persons surpass the ego's limited perception and align with the Holy Spirit's guidance.

A Course in Miracles also introduces the idea of miracles, which are recognized as changes in perception that come from the host to enjoy and forgiveness. Wonders, in that situation, are not supernatural activities but rather activities wherever individuals see the facts in someone beyond their vanity and limitations. These activities may be equally particular and societal, as people come to understand their heavenly character and the heavenly character of others. Miracles are seen as the normal result of exercising the course's teachings.
