A Class in Wonders is a set of self-study components published by the Base for Inner Peace. The book's content is metaphysical, and explains forgiveness as put on day-to-day life. Curiously, nowhere does the book have an author (and it is therefore outlined lacking any author's name by the U.S. Library of Congress). However, the writing was published by Helen Schucman (deceased) and Bill Thetford; Schucman has connected that the book's product is founded on communications to her from an "internal voice" she claimed was Jesus. The first edition of the book was published in 1976, with a revised version printed in 1996. Part of the material is a teaching handbook, and a student workbook. Because the very first model, the book has bought many million copies, with translations in to nearly two-dozen languages.

The book's roots could be this page  back to early 1970s; Helen Schucman first experiences with the "inner voice" resulted in her then supervisor, Bill Thetford, to contact Hugh Cayce at the Association for Study and Enlightenment. In turn, an introduction to Kenneth Wapnick (later the book's editor) occurred. At the time of the release, Wapnick was medical psychologist. Following meeting, Schucman and Wapnik spent around a year editing and revising the material.

Yet another introduction, this time of Schucman, Wapnik, and Thetford to Robert Skutch and Judith Skutch Whitson, of the Base for Internal Peace. The very first printings of the guide for circulation were in 1975. Ever since then, copyright litigation by the Foundation for Internal Peace, and Penguin Publications, has recognized that the content of the initial version is in people domain.

A Program in Wonders is a teaching product; the class has 3 books, a 622-page text, a 478-page student workbook, and an 88-page teachers manual. The components may be studied in the buy selected by readers. The information of A Class in Wonders addresses both the theoretical and the sensible, though request of the book's substance is emphasized. The text is mostly theoretical, and is a cause for the workbook's classes, which are useful applications.

The workbook has 365 classes, one for each time of the entire year, nevertheless they don't need to be done at a rate of 1 training per day. Probably most like the workbooks which can be common to the common reader from prior knowledge, you're requested to use the product as directed. But, in a departure from the "normal", the audience isn't required to think what's in the workbook, or even accept it. Neither the workbook nor the Course in Wonders is designed to complete the reader's understanding; just, the components certainly are a start.

A Class in Miracles distinguishes between understanding and perception; truth is unalterable and endless, while understanding is the entire world of time, change, and interpretation. The world of belief reinforces the principal some ideas within our minds, and keeps people separate from the reality, and split from God. Understanding is bound by the body's limitations in the bodily world, ergo limiting awareness. Much of the experience of the entire world reinforces the ego, and the individual's separation from God. But, by acknowledging the vision of Christ, and the style of the Sacred Nature, one understands forgiveness, equally for oneself and others.
