This book aims to rearticulate and reinterpret a Christian concept of God’s mission and evangelization in light of the universal, irregular, and transversal horizon of God’s narrative as it pertains to the realities of public sphere. Paul Chung maintains that mission serves the Word of God which is revealed in Jesus Christ by the power of the Holy Spirit for all. It is salient to develop a theology of Trinitarian mission through the perspective of God’s living “word-event” in a hermeneutical, intercultural fashion. Here, a Trinitarian concept of missio Dei is deepened and refurbished in light of God as the Subject of speaking: through Israel, the church, and the face of innocent victims and religious outsiders. This perspective contextualizes and widens the mission of God’s narrative and deepens its universality in light of the word event.
