She described these dictations as via an inner style that recognized it self as Jesus Christ. Schucman originally resisted these activities, but with Thetford's encouragement, she started transcribing the messages she received.

Over an amount of seven best acim podcast, Schucman transcribed what can become A Class in Miracles, amounting to three amounts: the Text, the Workbook for Students, and the Guide for Teachers. The Text sits out the theoretical foundation of the course, elaborating on the core concepts and principles. The Book for Students contains 365 lessons, one for each time of the year, made to steer the audience by way of a day-to-day training of applying the course's teachings.
