Other excellent books:
The Genius of Luther’s Theology: A Wittenberg Way of Thinking for the Contemporary Church by Robert Kolb and Charles Arand. Superb book.
We Confess Anthology: (We Confess Jesus Christ, We Confess the Church, We Confess the Sacraments). Excellent book.
Principles of Lutheran Theology , 2nd Ed. By Carl Braaten. About 90% of the writing is excellent and on solid ground, 10% is worth reading but discarding; but I urge that to all who read books outside Scripture and the Confessions. Valuable insights.
The Church from Age to Age by CPH. Readable recent compilation of six previous books on history. Excellent resource for everyone.
Three books used as text in Concordia Universities; edited by Steven Miller (Concordia, Irvine). These are usable with high education background.
Called to Believe: A Brief Introduction to Christian Doctrine , 2006.
Called to Believe, Teach, and Confess: An Introduction to Doctrinal Theology, 2006.
Called to be God’s People . 2006.
Testing Boundaries: Windows to Lutheran Identity , Charles Arand, 1995.
Here We Stand Hermann Sasse, 1938. A valuable book written in the crisis of the growing influence of Nazism and the Reformed movement in the German Church. Should be read with Bonhoeffer’s book (below), since they were contemporaries and worked to fight against the Reformed movement in Germany in the 1930’s.
Life Together Dietrich Bonhoeffer, 1954, but originally written as he was developing an underground seminary in Germany in the early 1940’s.
