Abstract
Missio Dei (“the mission of God”), and grounding the mission of the church in the character of God as a missionary God, is one of the most important theological (re-)discoveries of the twentieth-century. The concept is limited, however, if focused on one aspect of God as sending God, model of incarnational mission or empowerment for mission. This article argues that missio Dei is missio Trinitas (“the mission of the Trinity”). It explores the richness of missio Dei from an explicitly trinitarian perspective and its implications for local congregations, in conversation with missional church writers. The article argues that missio Trinitas places primary responsibility for mission with a Trinitarian God, invites the church to join God in the dance of (co-)mission, moves mission beyond church programs to a spirituality of mission, turns church attention to a whole gospel for the whole world, and calls all Christians into mission as communities rather than individuals. Ensuring a Trinitarian understanding of God and mission helps the church to remember the importance of divine agency, spirituality of mission, holistic mission and the mission of the whole people of God.
