Schucman, who was a medical and research psychiatrist at Columbia University's School of Physicians and Surgeons, began to have some internal dictations. She defined these dictations as via an inner voice that determined itself as Jesus Christ. Schucman originally resisted these experiences, but with Thetford's inspiration, she began transcribing the communications she received.

Over a period of eight years, Schucman transcribed what might become A Class in Wonders, amounting to three amounts: the Text, the Book for Pupils, and the Guide for Teachers. The Text sits out the theoretical base of the class, elaborating on the core methods and principles. The Book for Pupils includes 365 instructions, one for each time of the season, made to steer the reader via a day-to-day training of using the course's teachings. The Manual for Teachers gives more guidance on the best way to realize and teach the rules of A Program in Wonders to others.

Among the central themes of A Class in Miracles is the notion of forgiveness. The program teaches that true forgiveness is the key to internal peace and awareness to one's divine nature. Based on their teachings, forgiveness is not merely a ethical or ethical training but a simple shift in perception. It involves letting go of judgments, issues, and the notion a course in miracles podcast  failure, and as an alternative, seeing the entire world and oneself through the lens of love and acceptance. A Class in Wonders stresses that correct forgiveness results in the acceptance that individuals are all interconnected and that separation from each other can be an illusion.

The course presents a dualistic see of reality, distinguishing involving the ego, which represents separation, fear, and illusions, and the Holy Soul, which symbolizes love, truth, and religious guidance. It implies that the confidence is the foundation of putting up with and conflict, while the Sacred Soul offers a pathway to therapeutic and awakening. The goal of the course is to greatly help persons surpass the ego's confined perception and arrange with the Sacred Spirit's guidance.
