The essays in this volume constitute the proceedings of a conference on the work of Ddonald MacKinnon, this century's most influential British theologian. MacKinnon's work ranges from Aristotelean metaphysics to trinitarian reflection to Marxism. Surin's contributors start with MacKinnon's writings and move on to discuss such topics as his relation to Barth's theology, the controversy betwen realism and idealism, Trinity and ontology, incarnation and kenosis, the problem of evil, and MacKinnon's ethical reflections.
