In this question What major translations of the Bible are in the Public Domain and therefore not subject to Copyright? 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?
