Can I project more than 500 verses of Scripture over the course of a year? Or, an entire book of the Bible? In this question What major translations of the Bible are in the Public Domain? we established that most modern translations allow for fair use of a certain amount of Scripture - meaning that specifically you are allowed to reprint their translation without specific copyright provision.

To wit, using the NIV and the United States as an example:


  The NIV text may be quoted in any form (written, visual, electronic or audio), 


says that this would include projecting the words on the overhead screen.  No question there.

Question 1. Length:

According to this:


  up to and inclusive of five hundred (500) verses without express written permission of the publisher,


it says 500 verses.  Obviously, it is unlikely that any one sermon is going to need more than 500 verses.  But, does each sermon reset the counter?  In other words, over the course of a year, it would be likely that I would project more than 500 verses.  Where do I know that the counter resets?

Question 2. An entire "book"

It also says:


  providing the verses do not amount to a complete book of the Bible 


So, what if I'm preaching on 3 John?  Or Jude?  In those cases, it would seem very likely to just do the whole "book."  Are we breaking the law there?  And if so, how do I rectify the situation?
The length is the length of what you quote in a single document. So yes, a new sermon resets the counter. However, if you then publish all your sermons together in a single book, that single book becomes the reference document and can only contain 500 verses in toto (and of course, the rules on selling the text then come into play).

The terms are quite explicit about not amounting to an entire book of the Bible. So yes, you can't do all 25 verses of Philemon in one go. But then you could simply omit v1, which probably leaves enough to be useful.
