The writing is mainly theoretical, and is a basis for the workbook's classes, which are realistic applications.

The book has 365 classes, one for each day of the year, though they don't need to be performed at a rate of just one session per day. Possibly most just like the workbooks that are familiar to the average audience from previous knowledge, you are requested to use the um curso em milagres as directed. However, in a departure from the "normal", the audience isn't needed to believe what's in the workbook, as well as accept it. Neither the book or the Class in Wonders is meant to total the reader's understanding; only, the materials really are a start.

A Course in Miracles distinguishes between understanding and perception; the fact is unalterable and eternal, while understanding is the entire world of time, modify, and interpretation. The entire world of understanding reinforces the principal a few ideas inside our thoughts, and keeps people split from the facts, and separate from God. Perception is restricted by the body's limits in the bodily world, ergo limiting awareness. A lot of the ability of the entire world reinforces the vanity, and the individual's separation from God. But, by acknowledging the perspective of Christ, and the voice of the Sacred Heart, one learns forgiveness, both for oneself and others.
