Donald Mackinnon's theology defies easy stereotyping. He was an Anglo-Catholic who summoned the church to humility, a student of Barth and yet no "Barthian," a philosopher's philosopher marked by penetrating insight into the Christian gospel. In this remarkable study, Timothy Connor shows how all these lines converge in Mackinnon's reflections on the self-emptying of the Crucified. A beautiful and engaging work of scholarship.
