I’m going to assume a charitable stance on this, despite the obvious combativeness of the original poster.
First, one must remember that the catch phrase “Scripture Alone” comes with a great deal of theological explanation. While it may be sef-gratifying for a Roman Catholic to lampoon the idea based on only the phrase, the more honest approach would be to address the complete idea.
Lutherans accept Scripture Alone in a very particular way (sort of how Romans accept Papal Infallibility in a very particular and nuanced way.) We believe, teach, and confess that what is recorded in Holy Scripture is the infallible Word of God, and as such, it is the bedrock of what the Church believes, teaches, and confesses… i.e., it is the sole source and norm of Christian teaching and practice. It is uniquely verifiable, uniquely objective, and genuinely catholic for all Christians. The written words of the Prophets and the Apostles stand not on the individual prophet nor apostle, but on the God who speaks through them.
Lutherans also understand the Scriptures within the context of the One, Holy, Catholic, and Apostolic Church. It is the Church which carries forth and promulgates the Scriptures in every age, and the Church which is called to be faithful to the Word of God as she carries them. We know that the Word of God is powerful, that faith comes by hearing it, and that by faith grace is received unto salvation. We preach the Word of God, because God promised that His Word will never fail, nor falter-- we might be free to reject it, but it does not lose its inherent dignity based on our own evil response. We recognize that there is a history of interpretation to the Holy Scriptures, and that no one can interpret it by themselves… it is a Word held in community, held in the very Body of Christ, the Church.
When we say “Scripture Alone,” we distinguish the Holy Scriptures from any particular interpretation or application of them. You will notice, if you read them, that the Lutheran Confessions are repleat with quotations and references to the Church Fathers. Lutherans stand in the line of Jerome, Augustine, Ambrose, Chrysostom, Athenasius, Irenaus, Clement, Bernard, and many others. The Fathers were never perfectly united in their interpretation nor application of the Scriptures… hence the Councils, where at least in the first 7, the bishops gathered together to figure out how to settle conflicts amidst the bishops, based on the Word of God. If you read the canons of the seven ecumenical councils, you’ll find this to be so. It is even an ecumenical council, gathered around the Word of God, which condemns Pope Honorius as a heretic-- no structure and no individual is ever above the Word of God, and the Church is always called to be faithful to it.
So, when Lutherans stood on “Scripture Alone” in the 16th century, it was against a papal system which had deviated from both the Scriptures and the faithful Fathers. Lutherans argued for a simple faith and piety of the Patristic age, and Rome argued for… well, they argued for something else, based on high-medieval scholasticism, Aristotle, and Peter Lombard. Today, Lutherans still confess “Scripture Alone,” but in a catholic context that does not sever us from either the One Holy Church nor the ancient Fathers, nor the historic creeds. While the purported traditions which have been “handed down” can be called into question and challenged for their veracity, the Word of God continues to be God’s unalterable Word to us, His Church. Hence, Lutherans judge tradition by the Scriptures.
Grace and peace,
