Sounds like a good working and honest business relationship there. Most of the theological books I have read are written by guys who have been dead a good 100 years or more. A few exceptions though (Packer, Stott, Lloyd-Jones for example).

Of course, attributing authorship to a book that you didn’t write is a lie. So ultimately the fault is with the person who employed the ghost writer.

I know a Christian leader who has worked with a writer for many decades. They have a mutually beneficial relationship – his writer actually does most of the work and checks in with the leader regularly to ensure that he’s writing what the leader wants. But here’s the catch – everything they write together is given dual authorship, so everyone who buys the books know that the two men collaborated to write the book. Nothing untoward or unethical going on at all. (Philip Jensen and Tony Payne)
