This is to be a reflection on how to understand the discipline of theology, and practical theology in particular. The reflection entails what it means to engage in practical theology in the educational ministry of the church. In the process, a modest proposal will develop for the trajectory of practical theology that is characterized as a lifelong habitus that every Christian of all ages is engaged in as a part of God’s kingdom. This habitus is propelled by what I propose as the Three Pillars of Christianity: the Great Commandment, the Great Commission, and the Great Communion. These biblical maxims reveal the identity of and calling for the people of God within the very ministry of the triune God in his kingdom on earth.
