In 1 Thess 1:8 Paul claims: In every place your faith toward God has gone forth, so that we have no need to speak a word. We can smile at a call to stop missionary activity based on that verse. Lauri Thuren argues that Paul and his original addressees would smile at us for the very same reason, were they aware of many of the problems of modern Pauline scholarship. Expressions, which were never meant to be taken at their face value, may have promoted sophisticated but erroneous theological and historical reflections. This is due not only to the scholars' ignorance of ancient rhetorical and epistolary conventions, but also to their static attitude to the text itself.
Lauri Thuren offers a different study which is based on a natural, dynamic view of Paul's letters. In order to describe any theology beyond the texts, they need to be derhetorized. This means an identification of the persuasive devices in Pauline texts in order to filter out their effect on the theological ideas expressed. This principle is applied to a controversial issue in Pauline theology, the question of law. Lauri Thuren claims that Paul's exaggerated statements correspond to his hyperbolic way of thinking. His search for consistency in the Old Testament was a major reason for his revolt against the law.
