The rapid growth and near dominance of the Charismatic movement world-wide has inevitably raised the question as to its organic relationship with the Protestant Reformation. Answering this question is important not only for assessing Martin Luther's five-hundred-years-old legacy, but even more so for defining the nature, and predicting the future direction, of the movement. After critically evaluating two common approaches that are adopted for answering the question, namely, the historical and theological approaches, this article argues for and defends an exegetical methodology which enables Luther's expositions of Bible passages that are foundational to the Charismatic movement to more precisely direct such an investigation. As a validating test-case, it further engages Luther's expositions of Romans 12:3-8 to establish the extent of continuity, if any, with the Charismatic renewal. Even though not fully conclusive, as it only focuses on a single passage, the findings nevertheless demonstrate the significant advantages of the proposed method. [ABSTRACT FROM AUTHOR]
