I seem to recall the Apostle Paul wishing (in writing, no less!) that some of his detractors would emasculate themselves....If he wrote that down, one can only imagine what he was thinking.
Also probably one of the the most controversial verses in the Bible was when Jesus told his Apostles to sell their cloaks and buy a sword. What was He saying there? He had just spoke about being persecuted and I feel He was saying that you don't start a fight, but you have every right to defend yourself because the avalanche of criticism is coming. It seems many Christians today feel Christ wants them to lay down and be slaughtered for the cause. Jesus did that FOR us so we don't have to.
