Book excerpt: In this volume, on the basis of three consultations which took place in Seoul and Geneva (2016, 2017, 2018), theologians from Yonsei University's College of Theology in Seoul, South Korea, and from the Theological Faculty at the University of Geneva reflect together on three of the main challenges facing Christian theology today. First, questions related to religious pluralism and multiple religious belonging are addressed. Second, the `promise' of an enhanced human being through technology and other means is discussed. Third, the reality of the threat humanity represents to our ecosystem is considered. Each of these themes is examined from a Korean as well as from a Western European perspective, for Christian theology, in our day, can no longer afford to remain limited to its own geographical context.
