Over an amount of seven years, Schucman transcribed what can become A Course in Wonders, amounting to three amounts: the Text, the Workbook for Pupils, and the Handbook for Teachers. The Text lays out the theoretical basis of the class, elaborating on the key ideas and principles. The Book for Pupils includes 365 instructions, one for every day of the year, developed to guide the reader via a daily training of using the course's teachings. The Manual for Teachers provides more advice on how best to understand and show the principles of A Program in Wonders to others.

Among the key themes of A Program in Miracles is the idea of forgiveness. The program teaches that correct forgiveness is the important thing to internal peace and awareness to one's heavenly nature. In accordance with their teachings, forgiveness isn't only a moral or moral practice but a essential change in perception. It involves letting get of judgments, issues, and the belief of failure, and alternatively, seeing the planet and oneself through the lens of love and acceptance. A Program in Wonders stresses that correct forgiveness results in the acceptance that people are all interconnected and that separation from one another can be an illusion.

Yet another significant part of A Class in Wonders is its metaphysical foundation. The course gifts a dualistic see of fact, unique involving the pride, which represents separation, fear, and illusions, and the Holy Spirit, which symbolizes acim enjoy, truth, and religious guidance. It shows that the vanity is the origin of enduring and conflict, as the Holy Nature provides a pathway to therapeutic and awakening. The goal of the course is to help people transcend the ego's confined perspective and arrange with the Holy Spirit's guidance.

A Class in Miracles also introduces the thought of miracles, which are understood as shifts in belief that can come from the host to enjoy and forgiveness. Wonders, in this situation, are not supernatural events but instead experiences where persons see the truth in someone beyond their ego and limitations. These activities could be equally personal and social, as people come to understand their divine nature and the divine character of others. Wonders are viewed as the natural outcome of practicing the course's teachings.
