The book of Jeremiah testifies to disputes about theologies on various levels. Comparison of the Hebrew text and the version of the Septuagint shows large differences regarding the manner in which they speak of God. These differences suggest that the Greek translation tried to evade unusual, challenging, or provocative aspects attributed to God by mitigating or omitting them. The opposition between YHWH, with Jeremiah on his side, and the people together with their leaders shapes the main conflict within the book. The latter wish a “comfortable” relationship without liability, whereas God and his prophet require an exclusive liaison and determination. In some passages, Jeremiah has views which differ from those of YHWH. These texts illustrate that even a prophet has to “learn,” to open himself to God’s broader horizons and distinct plans. (d) Some features of the theological message of the book of Jeremiah are unique and set it apart from all other scrolls of the Bible. Jeremiah thus conveys a particular, independent view of YHWH, which sometimes stands in contrast to Deuteronomy, Isaiah, and other writings, although sharing the same belief in the one and only God. (e) The theological struggles within the book of Jeremiah find a continuation in the conflict of contemporary interpretations. Instead of explaining the various positions with diachronic considerations, it seems sounder to understand the rich variety of theologies therein as due to the different characters, altered situations and circumstances, and to the development of the individuals within the course of history.
