- Sola Scriptura: The Bible alone is the only infallible rule of faith (or the spiritual standard) for the church. It functions as the ultimate standard of authority in spiritual matters.
- There are other legitimate (but lesser) "rules of faith" such as catechisms, concordances, lexicons, commentaries, and the wisdom of godly leaders in the church. However, only Scripture is infallible.
- Presenting a biblical case for Sola Scriptura:
-Eternal life in the name of Jesus Christ (John 20:30-31):
*If the Gospel of John by itself is sufficient to bring about conversion of heart, then it stands to reason that the same is true of the three other gospel narratives.
*If the Gospel of John is sufficient to bring about our salvation, then how much more sufficient must the Bible in its entirety be as a rule of faith?
