You're not a lawyer, are you?
“Copyright protection, unlike patent protection, is automatic. As soon as the work is fixed in a tangible form it is protected under copyright law. You do not have to place a copyright notice on a work for it to be protected; however, it is advisable to include a copyright notice, because it tells others to whom the work belongs.
The author of the work is automatically the owner of all copyrights in the work unless the work was created in conjunction with the author’s employment. If the work is employment related, the employer owns the work in accordance with the work-made-for-hire doctrine in U.S. Copyright Law. (Refer to UC and Employee-Owned Copyrights for information on ownership of copyrights at the University of California.).”

If a person claims a church wrote the Bible, then he is claiming they have a claim to copyright.
