Unless Jesus is the central message of the Scriptures, many errors abound. The most common is moralizing. Moralizing is reading the Bible not to learn about Jesus but only to learn principles for how to live life as a good person by following the good examples of some people and avoiding the bad examples of others. That kind of approach to the Scriptures is not Christian, because it treats the Bible like any other book with moral lessons that are utterly disconnected from faith in and salvation from Jesus.
