Over a period of seven decades, Schucman transcribed what might become A Class in Miracles, amounting to three volumes: the Text, the Workbook for Pupils, and the Manual for Teachers. The Text lies out the theoretical basis of the class, elaborating on the primary concepts and principles. The Workbook for Pupils contains 365 lessons, one for every single day of the entire year, designed to steer the audience by way of a day-to-day training of using the course's teachings. The Manual for Educators gives more guidance on the best way to understand and teach the concepts of A Program in Miracles to others.

Among the central subjects of A Course in Miracles is the thought of forgiveness. The program shows that correct forgiveness is the main element to inner peace and awareness to one's divine nature. According to their teachings, forgiveness is not merely a ethical or honest exercise but a acim  change in perception. It involves letting move of judgments, grievances, and the notion of failure, and alternatively, seeing the entire world and oneself through the lens of enjoy and acceptance. A Class in Wonders emphasizes that correct forgiveness results in the recognition that individuals are all interconnected and that divorce from one another is definitely an illusion.

Another substantial aspect of A Program in Miracles is their metaphysical foundation. The course gift suggestions a dualistic see of truth, unique involving the confidence, which shows separation, anxiety, and illusions, and the Sacred Soul, which symbolizes enjoy, truth, and spiritual guidance. It implies that the vanity is the origin of enduring and struggle, while the Sacred Soul provides a pathway to therapeutic and awakening. The goal of the course is to help people transcend the ego's limited perspective and align with the Holy Spirit's guidance.

A Class in Miracles also introduces the concept of wonders, which are understood as adjustments in notion that can come from a host to love and forgiveness. Miracles, in this situation, aren't supernatural activities but rather activities wherever persons see the reality in somebody beyond their ego and limitations. These activities can be both particular and cultural, as people come to understand their heavenly nature and the divine character of others. Miracles are seen as the normal result of exercising the course's teachings.
