Recorded during Conference 2014: "Correctly Handling the Word of Truth: Reformed Hermeneutics Today." The first part of this speech will present a proposed structure for Jeremiah. A second part introduces and applies some critical methods to test the validity of the proposal. A third part assesses the profits and perils of the critical methods themselves and suggests what a Reformed Old Testament scholar can and cannot say. In this way the structure of the book of Jeremiah serves as a test case for the interplay of confessional integrity and quality control. A panel discussion follows this speech.
