Why Barth changed his mind: retrieval and rejection of the <i>extra Calvinisticum</i> in the theology of Karl Barth

Abstract Over the course of his career, Karl Barth changed his mind on the extra Calvinisticum , moving from a robust early affirmation to a final rejection in the later volumes of the Church Dogmatics . This article traces that theological shift, arguing that it was not incidental but necessitated by the internal logic of Barth’s doctrine of revelation. In contrast to recent trajectories that seek to retrieve the extra in defence of divine impassibility, Barth’s rejection was grounded in a conviction that God’s being is identical with God’s act – most fully revealed in Jesus Christ. This christological pressure led Barth to revise the scope and function of the extra until it became theologically untenable. The article situates this shift within the broader historical development of the doctrine and concludes by exploring its implications for reconciliation, kenosis, and divine ontology in contemporary theology.
