If you quote a living general authority, where do you request permission? Does the church own the copyright or does the individual speaker?
Also, you do need to submit separate requests to the church for each quoted item or for each project?
At one point, I think I had a link to the Church's copyright information but I've googled all morning and can't find it now. I did find THIS, which talks about using music.
The Church is subject to the copyright laws of the U.S. You can find the copyright law HERE. Specifically, you need to know what constitutes FAIR USE. Since copyright law is written in legal-speak, it's sometimes very difficult to interpret. That's why you can find several books that help interpret it. I have a much used copy of THIS ONE.
When quoting General Authorities, copyright ownership depends on your source. Sometimes it's the Church who owns the copyright and sometimes it's the General Authority. But either way, you start at the same place, which is The Church Copyrights and Permissions Office.* Contact them and ask for specifics on how to request permissions.
