The Evangelical and Reformed stream of the Church emphasizes God’s revelation of the Word in Scripture. When this is done by highlighting the function of Scripture while maintaining the equal ultimacy of the revelation of the Word via sacrament and the Spirit, this builds up the Church as a communion. But when Scripture is made the only authority or a more ultimate authority than the revelation of the Word through sacrament and the Spirit, and is autonomously used therefore to interpret all things according to a Two-Source View of authority, as with “Solo” Scriptura and Qualified Infallibility, this tears down the Church through the dynamic of denominationalism.
