The idea behind the Bible Field module is to provide a CCK field that can reference any body of work (not just Bibles) by book, chapter and verse. Below are some features:
The ability to reference a range or single point
A special Views 'range filter' that allows for search within a ranged entry (like chapters 2 to 10)
A compound Views filter that allows you to specify the granularity of the filter to book, chapter or verse
Books are pulled from a CVS file, so you can reference arbitrary bodies of work, or reference multiple works in the same node-type for cross-referencing
Chapter selectors are automatically adjusted to the number of chapters in the currently selected book
This module development was originally sponsored by Calvary Boise, who used the D6 version of this module in creative ways to tie together multiple kinds of media to their sources of inspiration.
