This article seeks to reappraise the scholarly work of Bede Jarrett OP by drawing out his debt to Sir Ernest Barker. A shared interest in medieval political and social institutions, and in the constitution of the Dominican Order as a model of voluntary association, infused Jarrett's thinking with the tenets of English political pluralism and enabled him to produce a body of work that paid as much attention to concrete political form as to social ethics. As such his work establishes links with nineteenth and early twentieth-century Christian Socialism, as well as echoing certain current preoccupations within political theology.
