Why are We Lutherans?
“It so happens that the people who lived in the Age of the Reformation knew and understood certain truths which were later forgotten and had to be learned from them again. The loyalty of the Evangelical Lutheran Church is accounted for by these experiences. We are faithful to this church, not because it is the church of our Fathers, but because it is the church of the Gospel; not because it is the church of Luther, but because it is the church of Jesus Christ. If it became something else, if its teaching were something other than a correct exposition of the plain Word of God, it would no longer be our church.
“It is not the Lutheran liturgy that matters. The church can get along without it if it must. It is not the Symbolic Books that count. If it should ever be demonstrated that they contain essential errors, we would be the first ones to cast them into the fire, for our norma normans, the standard by which we judge doctrines, is the Bible alone. Nor is it the Evangelical Lutheran Church, as a separate church in Christendom, that matters. The moment it becomes anything else than the stand on which is put the lamp which alone is a light upon our path, it becomes a sect and must disappear. We would not be Lutherans if we did not believe this!”
