Individual Edition. John Calvins Institutes of the Christian Religion has been one of the most important works in Christian theology for nearly five hundred years. The much-esteemed English translation of this work by Ford Lewis Battles, part of the Library of Christian Classics, has been the primary English translation for the past forty years. Now, for the first time, this translation is available in a convenient CD-ROM format. Built with Adobe PDF technology, the CD-ROM is compatible with both Windows and Macintosh operating systems.
