For an Organization that claims to be the heralder of the "Truth", it seems they have a history of mistakes. They assert that one MUST believe their "Faithful Slave" but who is that "Slave"? Is it Charles Taze Russell or ALL the anointed ones living on earth at a given time? Is the "faithful slave" merely a parable??
They've said that medical doctors were from the Devil! Did they or didn't they have God's holy spirit when they uttered this nonsense??
They've called the Alpha and Omega Jesus AND Jehovah a number of times. Which is it???
They've acknowledged that Gruber was a "spiritist" and that they wouldn't quote from his "inspired" translatation yet used his words to disprove the trinity afterward!
Can you think of area or specific things that would show anybody that Jehovah's Witnesses do not regularly teach the truth?
