Practical theology is an academic discipline that examines and reflects on religious practices in order to understand the theology that is enacted in those practices and in order to consider how theological theory and theological practices can be more fully aligned, changed, or improved. Richard Osmer explains that the four key questions and tasks in practical theology are:
- What is going on? (descriptive-empirical task)
- Why is this going on? (interpretative task)
- What ought to be going on? (normative task)
- How might we respond? (pragmatic task)
Practical theology consists of several related sub-fields: applied theology (such as missions, evangelism, religious education, pastoral psychology or the psychology of religion), church growth, administration, Darrell Guder et al.
