The purpose of this article is to understand the practical theological approach and practical wisdom in a recent trend of Christian Education. The practical theological approach in Christian Education has been changed from clerical paradigm, congregational paradigm, and to the model of God’s praxis as public paradigm. In God’s praxis God calls God’s people for God’s ministry in this world. God’s people are asked a leadership for this world in response to God’s praxis. What kind of virtue is needed for this leadership in God’s people? This article suggests the practical wisdom, that is phronesis, as the needed virtue. Practical wisdom is defined as a wise judgement in a particular context. This kind of judgement is for action in everyday life. The context for the action is considered as a significant factor for practical wisdom. Don Browning says the structure of practical wisdom which has inner and outer structures. The inner structure is the Golden Rule of an ethic of equal regard and the outer structure is narratives which have a vision level, ethical level, human’s needs and trend, environmental and social dimension, rule and role’s dimension. For a deep understanding of practical wisdom this article suggests a practical wise person(phronimos) who is onself as another. Oneself as another has a similar aspect with narrative identity. Narrative identity includes some characteristics as follows: osccillating between idem and ipse. discordant concordance, responsible self, practical ability, and social ethic. A practical wise person has these five characteristics. But this article suggests a more specific figure, who is Jesus, and his three ministries, which are priest, prophet, and Lord as servant. The true practical wise person is Jesus of three ministries based on practical wisdom. And Jesus as a practical wise person did a public ministry instead of a private ministry in this world. God’s people do public ministries by calling of the triune God as the true practical wise person. In the globalization age God’s people do public ministries in everyday life for all people. God’s people are asked to critically reflect on global economy, global polity, cultural homogenization, and other public areas in our context of life. For these public ministries God’s people need leadership as goverance, which is phronetic leadership. A Christian Educator’s task in the globalization is to develop the leadership of practical wisdom for transforming this world toward God’s kingdom.
