Wow you are feeling ambitious today!
Well one that always stuck in my craw was their boneheaded idea that nobody can understand the scriptures without them. To support this they use the story of the Ethiopian eunich who fatefully said, "how could I understand unless someone told me."
Of course when this happened the New Testament had not been written, and it would have been impossible for him to know of Christ's fulfillment of Isaiah unless someone actually told him. If this happened today the Ethiopian eunich could simply pick up a Bible, even a NWT, and find out who Jesus was.
Is that one, or is that more of an example of taking a verse out of context.
