Others have already highlighted some gems. My favourites:
"I started off in the bindery, stitching booklets. The brother told us to hurry up and put the covers on the booklets because Armageddon was coming. So we hurried up and got the covers on. And Armageddon hasn't come yet, so ..." (6.04) And that doesn't make you wonder if it's all bullshit?
"When you receive a direct invitation from Jehovah through his organization, this is the place he wants you to serve." (Barr, 17.45) So a letter from the branch headquarters is actually a communication from God?
"There's nothing here on this earth to compare with God's organization. There's never been anything, even in Bible times, to compare with what Jehovah has now or what he is doing." (Barry, 18.54). Moses parting the Red Sea, amateur stuff! Manna? Don't make me laugh! Jesus and the apostles healing the sick and raising the dead? Pretenders!
