Over a period of seven years, Schucman transcribed what can become A Program in Miracles, amounting to three amounts: the Text, the Book for Students, and the Manual for Teachers. The Text sits out the theoretical foundation of the course, elaborating on the primary concepts and principles. The Workbook for Students includes 365 lessons, one for each day of the season, made to steer the audience via a day-to-day training of applying the course's teachings. The Information for Educators offers more guidance on how to understand and teach the rules of A Class in Miracles to others.

One of many main themes of A Program in Miracles is the idea of forgiveness. The course shows that true forgiveness is the key to internal peace and awakening to one's divine nature. Based on their teachings, forgiveness isn't only a moral or honest exercise but a fundamental shift in perception. It requires making go of judgments, grievances, and the belief of sin, and alternatively, viewing the planet and oneself through the contact of love and acceptance. A Program in Wonders stresses that correct forgiveness leads to the recognition that individuals are all interconnected and that separation from one another is definitely an illusion.

Yet another substantial part of A Class in Miracles is their metaphysical foundation. The course presents a dualistic view of reality, unique between the confidence, which presents divorce, concern, and illusions, and the Holy Soul,  a course in miracles which symbolizes love, truth, and religious guidance. It suggests that the ego is the foundation of putting up with and struggle, whilst the Holy Heart supplies a pathway to therapeutic and awakening. The goal of the class is to simply help persons transcend the ego's limited perception and arrange with the Sacred Spirit's guidance.

A Class in Wonders also presents the concept of miracles, which are understood as changes in notion which come from the host to enjoy and forgiveness. Wonders, in that context, are not supernatural activities but rather activities wherever individuals see the facts in somebody beyond their confidence and limitations. These experiences may be both personal and societal, as persons come to realize their heavenly nature and the heavenly nature of others. Wonders are seen as the organic result of practicing the course's teachings.
