What might be learned, for theology, from recent interest in the complex love triangle of Nelly Barth, Charlotte von Kirschbaum and Karl Barth? I explore some aspects of how the story has been told, in and since Christiane Tietz's 2016 presentation and article, and argue that they expose deep-seated issues in and for the discipline of systematic theology. In particular, I draw attention to the focus on preserving the authority of the individual (male/masculine) author as the exemplar of theological practice; and to the reluctance to recognise the social, political and economic dimensions of sexuality and ‘domestic’ life. I argue that a properly ‘systematic theological’ approach to the Barth-von Kirschbaum story would involve critical and constructive theological reflection on theology's conditions of production: using historical contexts to help us recognise and respond to contemporary issues, without reducing such reflection to stories about individual authors.
