"Can you tell me the names of the ones Jesus appointed in Brooklyn as his Faithful and Discrete Slave in 1919?"
Individual names of the GB is not the important thing it was the organization as a whole not any one man,the same as the ones at Pentecost,the names of those there are not the important thing,men are imperfect and made mistakes and so is the organization ran by men the Zions Watchtower was not and still not infallible:
"They do not claim that this slave class is infallible, but they do view it as the one channel that the Lord is using during the last days of this system of things." Proclaimers p.626
"I'm struggling to think of anything that Russell taught that Jehovah's Witnesses still accept today"
Only the Scriptures are infallible but understanding the message from God then was like a dim light coming from the darkness,the darkness the bible students came from the false Churches into Jehovah's wonderful bright light of truth.When a person is in pitch black darkness and a bright light shines forth can one comprehend that bright light in its totality,NO,so how could the Watchtower understand from the beginning all of truths contained in Gods word.
Proverbs which is from God says,
"But the path of the righteous ones is like the bright light that is getting lighter and lighter until the day is firmly established." Proverbs 4:18
These ones just left main stream false worship and brought those beliefs with them ,its unreasonable to think they left the the false worship and suddenly in light of this passage came to full truth that they have now.The scriptures dont support such a belief:
New Living Translation
When I was a child, I spoke and thought and reasoned as a child. But when I grew up, I put away childish things.
They were spiritual babes coming into Jehovah's wonderful light,some still smoked,some still wore crosses and other things associated with the Churches
Does truth change? NO,but the understanding of that truth has and still become clearer
"If not going to war is your criteria for who the fds is. Then what about the amish?"
Thats was not the only criteria Christ looked at,the spiritual feeding and preaching his new incoming world Kingdom.Did the Amish preach about Gods Kingdom being established,NO
Matt 24-14
And this good news of the Kingdom will be preached in all the inhabited earth for a witness
