This study investigates the theoretical and practical necessity of intradisciplinary research between missional ecclesiology and practical theology, proposing a shift in the pastoral paradigm toward missional ministry. Missional ecclesiology was established at the theoretical level through intradisciplinary research among missiology, systematic theology, and biblical hermeneutics; to translate these theoretical insights into the concrete life of the local church, an intradisciplinary engagement with practical theology, which systematically studies the church's pastoral structures, is required. Based on the theological framework of Missio Dei (Mission of God), this study emphasizes that both missional ecclesiology and practical theology must be grounded in the theological foundation of God's mission, explaining the necessity of redefining and linking these two concepts. In doing so, it positions missional ecclesiology not merely as abstract discourse but as a theoretical bridge that integrates with the field-oriented areas of practical theology to facilitate a transition toward missional ministry. Furthermore, through a theological and literature-based analysis, this research examines how missional ecclesiology structurally reconfigures key sub-fields of practical theology: leadership, discipleship, and preaching. The analysis indicates that this integration provides a coherent theological foundation that shifts pastoral ministry from institution-centered management to an organic movement participating in God's mission. First, missional leadership rejects bureaucratic administration and heroic individual models, establishing the pastoral role as a cultural cultivator who horizontally distributes authority to strengthen the daily vocation of the laity. Second, missional discipleship utilizes a spiritual formation that balances interior maturity with public engagement, helping believers internalize their identity as sent agents across all areas of daily life. Third, missional preaching introduces a missional hermeneutic that interprets the entire biblical canon as God’s redemptive narrative, redefining the pulpit as a catalyst for apostolic sending rather than a tool for institutional preservation. In conclusion, this study demonstrates that just as intradisciplinary research was essential to construct the theoretical framework of missional ecclesiology, an intradisciplinary partnership with practical theology is necessary for its practical application and implementation, thereby contributing to ongoing discussions on the future direction of practical theology and highlighting missional ministry as a framework to sustain the church's work in contemporary society.
