Around a period of eight years, Schucman transcribed what would become A Class in Wonders, amounting to three quantities: the Text, the Workbook for Students, and the Information for Teachers. The Text sits out the theoretical basis of the course, elaborating on the primary concepts and principles. The Book for Pupils includes 365 instructions, one for every day of the season, developed to steer the audience through a everyday practice of using the course's teachings. The Guide for Teachers gives further advice on how best to realize and teach the rules of A Program in Wonders to others.

One of many key subjects of A Class in Wonders is the thought of forgiveness. The program teaches that correct forgiveness is the main element to inner peace and awareness to one's heavenly nature. Based on their teachings, forgiveness is not simply a moral or ethical exercise but a simple change in perception. It requires allowing go of judgments, issues, and the belief of sin, and instead, seeing the entire world and oneself through the lens of love and acim retreats acceptance. A Class in Wonders stresses that correct forgiveness leads to the recognition that people are typical interconnected and that divorce from each other is definitely an illusion.

Still another significant aspect of A Course in Wonders is its metaphysical foundation. The program presents a dualistic view of reality, unique involving the confidence, which shows divorce, anxiety, and illusions, and the Holy Spirit, which symbolizes enjoy, reality, and spiritual guidance. It implies that the vanity is the origin of enduring and conflict, while the Holy Soul offers a pathway to therapeutic and awakening. The target of the course is to greatly help people surpass the ego's restricted perception and arrange with the Holy Spirit's guidance.

A Course in Miracles also presents the idea of wonders, which are recognized as adjustments in belief which come from the host to enjoy and forgiveness. Miracles, in this situation, aren't supernatural activities but alternatively activities where individuals see the reality in some body beyond their vanity and limitations. These activities can be both personal and cultural, as people come to realize their divine nature and the divine character of others. Miracles are regarded as the normal outcome of training the course's teachings.
