Over an amount of eight decades, Schucman transcribed what can become A Program in Wonders, amounting to three amounts: the Text, the Book for Pupils, and the Handbook for Teachers. The Text sits out the theoretical base of the program, elaborating on the key methods and principles. The Book for Pupils includes 365 classes, one for every single day of the year, made to steer the reader through a everyday practice of applying the course's teachings. The Manual for Teachers provides more guidance on the best way to understand and teach the concepts of A Program in Miracles to others.

Among the main themes of A Class in Miracles is the thought of forgiveness. The course teaches that correct forgiveness is the key to internal peace and awareness to one's divine nature. Based on their teachings, forgiveness isn't only a ethical or honest practice but a acim shift in perception. It requires making go of judgments, grievances, and the notion of sin, and as an alternative, seeing the entire world and oneself through the contact of love and acceptance. A Course in Miracles emphasizes that true forgiveness contributes to the recognition that people are all interconnected and that divorce from one another can be an illusion.

Yet another significant facet of A Course in Miracles is its metaphysical foundation. The program gifts a dualistic view of reality, distinguishing between the vanity, which shows divorce, fear, and illusions, and the Sacred Soul, which symbolizes love, truth, and spiritual guidance. It shows that the confidence is the source of enduring and conflict, while the Holy Nature provides a pathway to therapeutic and awakening. The target of the class is to help persons transcend the ego's restricted perception and arrange with the Holy Spirit's guidance.

A Course in Miracles also introduces the thought of miracles, which are understood as changes in understanding that come from a place of love and forgiveness. Miracles, in this situation, aren't supernatural events but instead activities where people see the truth in somebody beyond their ego and limitations. These experiences can be both personal and social, as individuals come to appreciate their heavenly character and the divine character of others. Miracles are viewed as the normal outcome of training the course's teachings.
