Testament provides the reader with an introduction to metaphysical Bible interpretation by offering annotations and commentary from the works of Charles Fillmore and his students. Many Bible students learn their theology by reading the annotations and commentary of study Bibles. Study Bibles have a theological point of view, typically Catholic, Evangelical or Mainline Protestant. The Fillmore Study Bible makes this method of study available to the Metaphysical Christian.

This study bible uses the World English Bible translation, which is a contemporary-language update of the bible used by Charles Fillmore, the American Standard Version. The language of the WEB is not American nor British, but contemporary, world English, making the text pleasant to read for the broadest possible audience of global English speakers. The WEB differs from several contemporary-language translations by not adopting gender neutral language but it has provided footnotes when gender neutral language would be appropriate.
