A "true" christian really isnt possible. Not to an agreeable standard. There are thousands of denominations...many many more if you break it down to how within denominations there are individual followers who pick/choose what they want and ignore the icky stuff that their church might push as being good.
And some would argue that it would be the people who follow the bible the closest right? Yet look at those people...namely, the Phelps family. Not a single view they have with regard to their religion and the imaginary deity they follow is unjustified. Yet so so many people will claim they arent "true christians" because their views are unpleasant...and evil.
