The book consists of two main sections. In the first, Schmid traces the notion of "theology" from its earliest use, in Greek philosophy, through the medieval period and to today. He pays close attention to "biblical theology", particularly the different understandings of this idea as something emanating from the Hebrew Bible itself versus something that readers impose onto the biblical text. He also tracks the influence of the discipline of comparative religion on biblical theology, especially with regard to the growing division between biblical and systematic theology. In the second part, Schmid focuses specifically on "implicit" biblical theology, that is, theological reflection apparent within the Hebrew Bible itself. He provides several examples, such as the theologization of the law that resulted from inner-biblical exegesis and Jeremiah's universal theology of history.
