Around a period of eight decades, Schucman transcribed what can become A Course in Miracles, amounting to three quantities: the Text, the Book for Students, and the Handbook for Teachers. The Text sits out the theoretical foundation of the program, elaborating on the key ideas and principles. The Workbook for Students includes 365 classes, one for each time of the season, developed to guide the reader through a daily exercise of applying the course's teachings. The Information for Educators provides more guidance on the best way to realize and teach the axioms of A Course in Miracles to others.

Among the central themes of A Program in Wonders is the idea of forgiveness. The course teaches that correct forgiveness is the important thing to internal peace and awakening to one's divine nature. According to their teachings, forgiveness isn't simply a ethical or honest training but a elementary change in perception. It requires making go of judgments, issues, and the understanding of failure, and alternatively, seeing the planet and oneself through the lens of enjoy and acceptance. A Course in Miracles highlights that correct forgiveness results in the recognition that individuals are interconnected and that separation from one another can be an illusion.

Yet another substantial facet of A Course in Miracles is its metaphysical foundation. The course presents a dualistic view of fact, unique between the confidence, which represents separation, anxiety, and illusions, and the Holy Spirit, which symbolizes a course in miracles , reality, and religious guidance. It implies that the ego is the foundation of suffering and conflict, as the Sacred Nature provides a pathway to healing and awakening. The goal of the class is to help persons transcend the ego's limited perspective and arrange with the Sacred Spirit's guidance.

A Class in Wonders also introduces the concept of miracles, which are recognized as shifts in understanding that can come from a place of love and forgiveness. Wonders, in this context, aren't supernatural functions but rather activities where people see the truth in somebody beyond their confidence and limitations. These activities can be both particular and cultural, as people come to realize their divine character and the heavenly character of others. Wonders are seen as the normal outcome of exercising the course's teachings.
