Around a period of seven decades, Schucman transcribed what would become A Course in Miracles, amounting to three sizes: the Text, the Workbook for Students, and the Handbook for Teachers. The Text sits out the theoretical foundation of the class, elaborating on the primary methods and principles. The Workbook for Pupils contains 365 instructions, one for every time of the season, developed to guide the reader via a everyday exercise of applying the course's teachings. The Manual for Teachers offers further advice on the best way to realize and teach the principles of A Course in Wonders to others.

One of the key subjects of A Program in Wonders is the idea of forgiveness. The course teaches that correct forgiveness is the key to internal peace and awakening to one's divine nature. In accordance with its teachings, forgiveness is not only a moral or moral exercise but a a course in miracles shift in perception. It requires allowing move of judgments, grievances, and the perception of failure, and instead, viewing the world and oneself through the lens of enjoy and acceptance. A Program in Wonders highlights that correct forgiveness contributes to the recognition that people are interconnected and that separation from one another can be an illusion.

Another significant aspect of A Program in Wonders is its metaphysical foundation. The class gifts a dualistic view of reality, distinguishing between the pride, which represents separation, concern, and illusions, and the Holy Heart, which symbolizes love, reality, and spiritual guidance. It implies that the ego is the source of enduring and struggle, as the Holy Nature provides a pathway to therapeutic and awakening. The target of the course is to greatly help individuals transcend the ego's restricted perspective and align with the Holy Spirit's guidance.

A Program in Miracles also presents the thought of wonders, which are recognized as changes in understanding which come from the host to enjoy and forgiveness. Wonders, in that context, are not supernatural events but rather experiences wherever persons see the facts in someone beyond their confidence and limitations. These experiences may be both personal and interpersonal, as individuals come to understand their divine nature and the heavenly nature of others. Miracles are seen as the normal result of exercising the course's teachings.
