The beginnings of A Course in Wonders could be tracked back again to the cooperation between two individuals, Helen Schucman and William Thetford, both of whom were prominent psychologists and researchers. The course's inception happened in the early 1960s when Schucman, who had been a scientific and research psychiatrist at Columbia University's School of Physicians and Surgeons, started to experience some internal dictations. She defined these dictations as coming from an internal voice that discovered itself as Jesus Christ. Schucman initially resisted these activities, but with Thetford's inspiration, she started transcribing the messages she received.

Over an amount of seven years, Schucman transcribed what would become A Class in Miracles, amounting to three sizes: the Text, the Workbook for Pupils, and the Manual for Teachers. The Text lies out the theoretical basis of the program, elaborating on the primary concepts and a course in miracles. The Workbook for Students includes 365 instructions, one for every day of the year, developed to guide the audience by way of 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 show the concepts of A Class in Wonders to others.

Among the main subjects of A Class in Wonders is the thought of forgiveness. The course teaches that true forgiveness is the important thing to internal peace and awareness to one's divine nature. Based on their teachings, forgiveness isn't simply a moral or ethical exercise but a elementary change in perception. It requires letting move of judgments, issues, and the notion of failure, and instead, seeing the planet and oneself through the contact of enjoy and acceptance. A Class in Wonders emphasizes that correct forgiveness leads to the acceptance that we are interconnected and that divorce from each other is an illusion.

Another significant aspect of A Class in Miracles is their metaphysical foundation. The program gifts a dualistic view of truth, distinguishing between the pride, which shows separation, fear, and illusions, and the Holy Spirit, which symbolizes enjoy, truth, and spiritual guidance. It suggests that the ego is the foundation of suffering and struggle, whilst the Sacred Heart supplies a pathway to therapeutic and awakening. The goal of the class is to simply help individuals transcend the ego's restricted perception and align with the Sacred Spirit's guidance.
