We may be debating something unnecessarily. I see that you recognize the Society has "abused the FDS concept." But, while I may not be in sync with your point, I don't think I'm missing the original point--Honesty's, which was...
Do Jw's agree with Romans 6:16 that if one obeys someone they are slaves of the one they are obeying?
While Jesus certainly made an important statement about not being able to serve God and riches, the illustration he used, ("no servant can be the slave of two masters,") should not really be limited to "riches," should it? Since we are here discussing Jehovah's Witnesses, I think it's appropriate to ask, how do they apply this scripture? Do they limit its interpretation to riches? I'm sure you know they don't. They use that scripture to teach that anything can pervert pure worship. I very much agree that JWs do not "hate" Jesus--in the sense that they openly demonstrate hate for him. But do you remember what the WTS has always said about that word, "hate"?
Insight on the Scriptures, Volume 1, p. 1042
In the Scriptures the word "hate" has several shades of meaning. It may denote intense hostility, sustained ill will often accompanied by malice. Such hate may become a consuming emotion seeking to bring harm to its object. "Hate" may also signify a strong dislike but without any intent to bring harm to the object, seeking instead to avoid it because of a feeling of loathing toward it. The Bible also employs the word "hate" to mean loving to a lesser degree.
Insight on the Scriptures, Volume 2, p. 229
The account tells us that Leah was "hated." (Ge 29:31, 33) But it also recounts that, after he had finally got Rachel, Jacob "expressed more love for Rachel than for Leah." (Ge 29:30) Undoubtedly Jacob did not hold malicious hatred for Leah but viewed Rachel more lovingly, as his favorite wife. He continued to care for Leah and to have relations with her. Leah’s being "hated," therefore, would merely mean that Jacob loved her less than Rachel.
So, since Jesus probably did not mean that 'slaving for riches' would mean "intense hostility" or even a "strong dislike" of God, he probably meant "loving to a lesser degree." And I'd say this is very much in line with Honesty's orginal point. Not that JWs feel intensely hostile toward Jesus--but that, in devoting themselves so wholeheartedly to the WTS, they have both become slaves to them and, sadly, loved Jesus less.
