The Augsburg Confession is the single most-important confession of faith among Lutherans today. However, it is often taught either from a historical perspective or from a dogmatic one. Yet the context out of which it arose was far more practical and lively: marked from the outset as confessions of faith in the face of fierce opposition and threats. The original princely signers, while clearly outlining the teaching of their churches, were also staking their lives on the witness to the gospel that had been emanating from Wittenberg since 1517, when Martin Luther first published his Ninety-Five Theses. By situating both the history and the theology of this document within the practice and life of faith, Timothy J. Wengert shows just how relevant the Confession's witness is for today's Lutheran parishes and their leaders by unlocking how its articles can shape and strengthen the church's witness today.
