Many Bible-based ministries usually start with the creed concerning the infallibility of Scripture. Fortunately, within the Bible, we have a model for this type of blind faith. Acts 17:11 tells of the Bereans who were excited about this new teaching, but not so ignorant that they didn't verify what was said (or written to them). I believe that it is safe to believe that people make mistakes. In passing down the Bible from one generation to the next, from one language to the other, from one king or pope to their replacement, words and interpretations of men have altered the text.
That being said, I believe that God has maintained His wisdom in the Bible more-so than any other Scriptures. But to overcome the hand of man on the Bible, some standards for discerning the Word of God must be established. These are standards that I have found to not only prove the inerrancy of the Bible, but to remove my personal views - thus, keeping me from interpreting the Bible, but have the Bible interpret itself as a perfect Teacher.
Note: Sometimes the linked Bible verse below will not be so well-known. Make sure you click and see that this is deeper than your average Bible class!
Personally, I have found that it is usually our interpretation of a single verse that puts us into trouble - worse if there is no verse at all to support our claims (ie. God helps those who help themself). Although I will not bombard you with everything, I have found that a verse, within context, repeated in interpretation 10 times is worthy of dogma. This happens many times throughout the Bible and is far from the dogmatic beliefs of the cults.
I have more granular and lengthy standards, including applying original language and thought as well as Apocrypha writings, early church documents, as well as statements by (un)cultured Christians (Example) If you are in agreement to the standards listed above for interpretation and discernment of the Bible, let us begin our discussions in discipleship from the beginning!
EDIT: I forgot to mention, but the infallibility of the Bible has another check to keep us from mis-interpretation. That is, a single verse can invalidate the interpretation of others. However, in the event that an interpretation is developed from 5 and more especially 10 passages, it is more likely that the one invalidating verse may have been misinterpreted. Most often, though, a teaching can be proven to be outside the tutorage of the Scriptures and more on the theologies and traditions of the day.
