The researcher in this paper tries to suggest proper indicators of the missional church based on his critical evaluation to Dr. Kookil Han’s study of missional churches in Korea. The researcher describes ‘Missio Dei,’ ‘the Bible-centered evangelicalism,’ ‘the emphasis of indigenous culture,’ ‘practicalism,’ ‘the focus on the essence of the church,’ ‘dynamics of the Holy Spirit,’ ‘ministry of lay people,’ and ‘the pursuit of the dispersive church’ as the main characteristics of the missional church. The researcher highly evaluates Dr. Kookil Han’s endeavor to study emerging missional churches in Korea. However, the researcher points out that some cases which Dr. Han introduced, do not reach to the criterion of the missional church in terms of the main characteristics of the missional church. In this paper, Songahk church, Hannam first church, Sungkwang church, Kwangyang-Daekwang church, Sungam church are described as emerging missional churches in Korea. From the common characteristics of these churches, the researcher factors out 12 indicators for the missional church: 1) the missional church is to be on evangelistic ecumenicalism based on theology of Trinity; 2) the missional church should exercise good influence to the local community; 3) the missional church needs to contribute to the development of the local society; 4) the missional church ought to understand the true value of the church; 5) the missional church should endeavor to be a living community; 6) the missional church must not have any internal conflict among people in the church for more than ten years; 7) the missional church needs to endeavor for the cross-cultural mission; 8) the missional church should support the horizontal structure in which the clergy and the laity lead the faith community together; 9) the missional church is to catch up with the changing trend of the region and the times; 10) the missional church should be financially independent; 11) the missional church ought to be ecumenical in working with others; 12) the missional church must work for the larger community where the local church stands.The researcher lastly argues that Korean church leaders need to dig out more missional churches in Korea and establish a reliable criterion indicating the missional church for developing a biblically faithful and culturally relevant missional ecclesiology in Korea.
