This thesis addresses the division that exists between theory and praxis. Theology in general and practical theology as a specific discipline has allowed this division to arise and indeed grow. The problem facing us is that faith communities now operate out of blind theory and/or blind praxis. To address this situation a reintegration of the theory and practice of the entire ecclesial praxis is needed. This thesis proposes “Practical Theological Ecclesiology” as the way forward. Practical theological ecclesiology is defined as: The dynamic critical purposeful engagement with the human-divine interactive life of the ecclesial praxis to: ground, integrate, align and improve its essence and expression dimensions as the revelational incarnational sign of God and his purposes in and for the world and directed toward his eschatological kingdom goal. Practical theological ecclesiology addresses both the abstractness of pure ecclesiology and the pragmatics of the praxis through the development of an operational ecclesiology model that integrates the essence, expression and goal dimensions of the ecclesial praxis. By applying the operational ecclesiology model to praxis, practical theological ecclesiology, through the tasks of grounding, integrating, aligning and improving, uncover the gaps that exist in and between the theory and praxis of a faith community. The resulting analysis provides ecclesial pictures of what is, compared to what should be, according to the operational ecclesiology model. The areas of ecclesial life which need to be grounded, integrated, aligned and improved are therefore exposed for ongoing work. Historical and contemporary research of the Christian Community Churches of Australia, provide the data for a case study which illustrates the potential and the analysis process of practical theological ecclesiology. The research underlines the importance of having an integrated operational ecclesiology, of grounding and integrating the theory, of aligning of theory and praxis, and of providing improvement direction for the praxis, thus removing theory and praxis division, avoiding both blind theory and blind praxis, and giving a clear pathway for the future . / Practical Theology / D.
