An interesting section of the same article supporting the necessity for Scriptural Authority:
Opposition in the Name of Fidelity
The Protestant reformers, inspired with zeal for Gods word, went one step further. Under the banner of sola scriptura they proclaimed the Bible as the only infallible authority for Christians. That meant that both Tradition and Church authority could be opposed in the name of fidelity to Scripture.
Funny thing, however: from the outset of the Reformation, the movement that agreed on the supreme authority of the Bible disagreed bitterly on what the Bible said. The Protestant church was divided from the beginning. Nearly 500 years later, we see thousands of competing churches claiming the same Bible and sola scriptura heritage.
Thats because the Bible is a collection of written documents. And one of the truths about all written documents, even if they happen to be inspired by the Holy Spirit, is that they can be interpreted differently by different people.
Someone Has to Have the Last Word
The Catholic Church!
