As the title denotes, this book Biblical Citations fromA Course in Miracles is a compilation of Biblical references and verses as contained from another book called A Course in Miracles. The latter was transcribed by Drs Helen Schucman and William Thetford, former Professors of Medical Psychology at Columbia University's College of Physicians and Surgeons in New York City through an "inner dictation" from the "Voice" believed to be that of Jesus Christ. The materials were received and noted by Dr Schucman and then typed by Dr Thetford as they were read to him the following day. It took them seven and a half years to complete the Course.
This book (Biblical Citations fromA Course in Miracles) is one way of introducing the Course to readers with the familiar Bible verses as entry points. Have a read and find out whether the Course is really channeled materials from Jesus Christ.
