Around a period of eight decades, Schucman transcribed what can become A Course in Wonders, amounting to three sizes: the Text, the Workbook for Students, and the Manual for Teachers. The Text sits out the theoretical base of the program, elaborating on the key concepts and principles. The Book for Students contains 365 lessons, one for each time of the season, made to guide the reader through a daily exercise of applying the course's teachings. The Guide for Teachers provides more guidance on how to understand and train the principles of A Program in Miracles to others.

Among the main themes of A Class in Miracles is the notion of forgiveness. The program shows that correct forgiveness is the important thing to inner peace and awakening to one's divine nature. In accordance with its teachings, forgiveness is not merely a moral or ethical exercise but a essential shift in perception. It requires making move of judgments, grievances, and the perception of failure, and as an alternative, seeing the entire world and oneself through the contact of love and acceptance. A Class in Wonders stresses that true forgiveness contributes to the acceptance that individuals are interconnected and that divorce from each other can be an illusion.

Still another significant part of A Program in Wonders is its metaphysical foundation. The class gifts a dualistic see of truth, unique involving the ego, which presents separation, anxiety, and illusions, and the Sacred Spirit, which symbolizes enjoy, truth, and spiritual guidance. It shows that the pride is the source of enduring and struggle, while the Holy Spirit provides a pathway to healing and awakening. The target of the course is to greatly help people transcend the ego's confined perspective and align with the Holy Spirit's guidance.

A Class in Wonders also introduces the concept of miracles, which are understood as changes in belief that come from a place of enjoy and forgiveness. Miracles, in that situation, are not supernatural activities but rather experiences where individuals see the facts in somebody acim beyond their ego and limitations. These activities can be both personal and cultural, as people come to realize their heavenly character and the heavenly nature of others. Wonders are viewed as the organic outcome of practicing the course's teachings.

The course more goes in to the nature of the self, proposing that the true self isn't the vanity nevertheless the internal divine fact that is beyond the ego's illusions. It implies that the confidence is just a false self that people have made based on concern and divorce, while the actual home is forever attached to the divine and to all of creation. Thus, A Program in Wonders shows which our supreme purpose is to consider and recognize our correct self, letting go of the ego's illusions and fears.
