"Spirit-directed" or "inspired." Such nonsense. Do you know what "inspired" generally means to a layman? It means "guided by holy spirit" or "spirit-directed." Word games, indeed.
"Vindication of Jehovah's name" generally means to the members, "justification of His will to cause things to become, proving He has the right and the proper motives for doing what He does."
"Vindication of Jehovah's Sovereignty" would essentially mean the same thing, but maybe easier to understand- "Justification of His Rulership."
"Sanctification of His Name" would mean to a member, "the cleaning up of that name" or removal of stains upon it. So it would be the "proving He has the right and the proper motives for doing what He does" or the "justification of His will." Basically the SAME SAME SAME to everyone except an English Language Expert.
But leaning toward the specific difference from the standpoint of exact English language (and forgetting that Hebrew and Greek were the languages of the Bible, not English), I liked the more specific refinement when I was a blind follower.. It gave something to try to understand, it gave something to bother reading in-depth into the article that covered it, it made the Governing Body look like they were actually progressing our understanding.
The other issue Barbara Anderson talked of- "The New Order" vs. "The New World." I have to say I agree with Barb that they just should have said the "men" at Bethel don't like the negative attachment to Nazis that one term gives even though there's nothing wrong with the term.
