Now you might not find this particularly significant, but it has implication for how Luther has been read by modern theologians. Ever since Schleiermacher and the demise of the scriptural principle, modern theologians have been searching for an alternative principle. Most have held it is Christ and therefore used a theological method that deduces all the articles of the faith from Christology. The exclusive focus on Christ as the meaning of Scripture present in modern Luther interpretation comes from this impulse. It lay in the background of the phenomenon of gospel-reductionism.
Of course, it is important to recognize that Luther does view Christ and the gospel as central to the message of the Bible. Nevertheless, such a message of salvation is meaningless apart from the whole of the creed. The article of the gospel doesn't make any sense if it is not situated between the article of creation and the work of the Holy Spirit within the Church. Moreover, if taken too far, overemphasis on the article of the gospel can lead to a kind of Gnosticism (which Gustaf Wingren warns against) which focuses so exclusively on redemption to the point that it denies importance of the restoration and fulfillment of creation. This, as I have pointed out in the past in great detail, ultimately distorts how redemption itself is understood. Redemption ultimately comes to be understood as the overcoming one's creaturely status and a denigration of the orders of creation.
