The Popular Commentary is Lutheran to the core. Dr. Paul E. Kretzmann's commentary reproduces Luther, his theology and religion, his faith and piety. Dr. Kretzmann's commentary offers to Lutheran Christians nothing but sound, scriptural doctrine on the basis of believing, Biblical scholarship. Because of this, the Popular Commentary possesses a unique distinction. It is a popular commentary in the truest sense of the term; a commentary for the people and offering to the people nothing but unalloyed exposition of the Bible.
