This was brought up in another thread and I thought it was interesting. Would you go to a church where the pastor did not use your preferred Bible version? I would. We came to our church with our pastor using the KJV and we used the NIV. We've since began using the ESV and really enjoy it - and our pastor is now preaching mostly out of the NIV, although he also uses the KJV and the NASB depending on the wording of the passage.
