A Class in Wonders, often abbreviated as ACIM, is a profound and significant religious text that appeared in the latter half of the 20th century. Comprising around 1,200 pages, that detailed perform is not really a book but a complete course in spiritual transformation and inner healing. A Course in Wonders is unique in their way of spirituality, drawing from various religious and metaphysical traditions presenting something of thought that aims to lead people to a state of internal peace, forgiveness, and awareness with their true nature.

The origins of A Program in Wonders could be followed back to the collaboration between two individuals, Helen Schucman and Bill Thetford, both of whom were distinguished psychologists and researchers. The course's inception happened in the first 1960s when Schucman, who was a scientific and study psychologist at Columbia University's University of Physicians and david hoffmeister , began to see a series of inner dictations. She described these dictations as via an internal voice that recognized itself as Jesus Christ. Schucman originally resisted these experiences, but with Thetford's encouragement, she started transcribing the communications she received.

Over a period of eight decades, Schucman transcribed what can become A Course in Wonders, amounting to three volumes: the Text, the Book for Students, and the Information for Teachers. The Text lies out the theoretical foundation of the course, elaborating on the primary concepts and principles. The Workbook for Pupils includes 365 classes, one for every time of the entire year, developed to guide the reader through a everyday training of using the course's teachings. The Information for Teachers gives more guidance on the best way to realize and train the axioms of A Class in Miracles to others.

One of the key styles of A Class in Miracles is the thought of forgiveness. The class shows that true forgiveness is the main element to internal peace and awareness to one's divine nature. In accordance with its teachings, forgiveness is not only a ethical or moral practice but a basic shift in perception. It involves letting get of judgments, grievances, and the perception of sin, and instead, seeing the entire world and oneself through the contact of love and acceptance. A Course in Wonders stresses that correct forgiveness results in the recognition that people are interconnected and that divorce from each other is an illusion.
