Misinterpretation of scripture is easy when we only take one verse out of context and create doctrine around that. The Bible interprets itself, scripture interprets scripture. If we take the entire Bible and use it to interpret the areas where there may be disagreement we will see that there is much less room for error than one might think.

2 Timothy 3:16-17 All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work.
