Over a period of seven decades, Schucman transcribed what can become A Program in Wonders, amounting to three amounts: the Text, the Book for Pupils, and the Guide for Teachers. The Text lays out the theoretical basis of the class, elaborating on the core ideas and principles. The Workbook for Pupils contains 365 classes, one for each day of the season, designed to guide the reader through a day-to-day exercise of applying the course's teachings. The Information for Teachers offers more advice on the best way to understand and teach the maxims of A Course in Wonders to others.

One of many central subjects of A Class in Wonders is the notion of forgiveness. The class teaches that correct forgiveness is the main element to inner peace and awareness to one's divine nature. According to its teachings, forgiveness is not only a moral or ethical exercise but a fundamental shift in perception. It requires making get of judgments, issues, and the perception of failure, and alternatively, viewing the world and oneself through the contact of enjoy and acceptance. A Class in Wonders emphasizes that correct forgiveness results in the recognition that individuals are typical interconnected and that divorce from each other is an illusion.

Another substantial part of A Class in Wonders is its metaphysical foundation. The class gift ideas a dualistic view of fact, unique between the pride, which represents divorce, anxiety, and illusions, and the Sacred Nature, which symbolizes love, reality, and spiritual guidance. It implies a course in miracles that the pride is the foundation of suffering and conflict, as the Sacred Spirit offers a pathway to therapeutic and awakening. The target of the program is to simply help people surpass the ego's restricted perception and align with the Holy Spirit's guidance.

A Class in Miracles also introduces the thought of wonders, which are recognized as changes in understanding which come from the place of love and forgiveness. Miracles, in that context, aren't supernatural events but rather experiences wherever individuals see the reality in someone beyond their pride and limitations. These experiences could be equally particular and cultural, as individuals come to realize their heavenly nature and the heavenly character of others. Wonders are regarded as the natural result of exercising the course's teachings.
