Shadow,
I think there is really a fundamental difference in our approach. Do you believe there is no difference between rulership/governance over people and religious authority?
You keep using the comparison to King David. King David was not a religious leader. He did not deliver religious edicts to his people. He was a governmental ruler.
Pharisees and Sadducees would be a fitting comparison, but Jesus rejected their authority, encouraged others to reject their authority, and sought out those the Pharisees rejected. I can provide Scriptural examples of each of these, but I am sure you know where they are.
If religious authority should be viewed as equal to governmental authority, why are Catholics less correct than Witnesses?
Catholicism teaches things that are not based on Scripture and things that are directly contrary to Scripture. Jehovah's Witnesses teach things that are not based on Scripture and things that are directly opposed to Scripture. Do we draw the distinction between the two as to which things they are teaching falsely? If so, why? (1 John 4:1; Matthew 24:23-28; John 9:1-10:18; Mark 13:21-23)
By the measure the Jews used to determine a false prophet, for instance, the Catholic Church as an organization is squeaky clean. (Deuteronomy 18:20-22) Does that make them the true religion, whose authority must be obeyed?
Some scriptures indicating the existence of separate groups
I wholeheartedly agree!
Two separate groups are indicated in every verse you cited. Those who are blinded vs. those who are not, those who are perishing vs. those who are not, those who originate with God (see 1 John 4:1) and those who do not, those who are Christ's brothers and those who are not (among whom would be some who treated the brothers of Christ kindly, anyway), those taken out of the nations for God's name and those who are not, those delivered by the ransom and those who are not. Two groups. Like the sheep and the goats. Like the wheat and the weeds. Like the fish in the dragnet and those not caught. Like those invited to the feast and those not invited.
From these Scriptures, none of which even comes close to teaching the doctrines I asked about, I take it that you actually have trouble rationalizing this for yourself. If you are submitting as if to a governmental authority, please explain why Scripturally.
In other words, Scripturally speaking, why should I submit to the Catholic Church just because Uriah submitted to David's rulership.
Since you are focusing on the position held by the Governing Body and not on their claims, their failed prophecies, or their teachings, please explain why the same exact line of reasoning does not apply to the position held by the Papacy and Bishops of Roman Catholicism. The two claim the exact same position as far as I can tell. It is a clergy class complete with a doctrine of magisterium "teaching authority."
The only distinction I can see is that one authority does not publicly claim infallibility. But they expect the authority to be regarded as infallibile anyway and they punish dissenters as heretical.
No, you should not be expelled for contradicting a human teaching. No doubt some already have been and more will be in the future.
Well, I sincerely expect I will be. I hope you will still share a meal with me, anyway. Your heart must hurt for what you see.
Respectfully,
