In 2008, the author wrote an article on sex and eros (Scheffler 2008) without having read or even being aware of Le Roux's article.2.His friendship also reminds me of an adage expressed by Jürgen Moltmann at a meeting during his visit to South Africa in 1978: 'Besides the obligation for Christian brotherhood there exists fortunately also the privilege of Christian friendship'.In this article, Jurie Hendrik le Roux's contribution to the theological endeavour is explored. His wide interdisciplinary interest that bears fruit in various fields of his work proved (at least in his case) that the adage 'Jack of all trades and master of none' is invalid. His research in sociology, Church history and philosophy will be discussed in so far as it contributed to his main interest, Old Testament Studies. In what follows, I will therefore make some remarks on Le Roux's work on sociology, Church history, ancient Israelite historiography, research history and also on exegetical methodology, Pentateuchal studies, philosophy and hermeneutics. My method will be to indicate the links between these disciplines as facets of one huge theological endeavour.Intradisciplinary and/or interdisciplinary implications: This article gives an overview of the theological contribution of the Old Testament scholar Jurie le Roux. Over many years, his work in the field of Old Testament Studies stretched into many other fields -as indicated in the article -such as sociology, Church history and philosophy.
