When leading congregations, Christian leaders must be aware of both explicit and implicit theologies. What people believe determines how they act, and because of that, church members will continue to act according to the theologies that they hold. Without an awareness of both explicit and implicit theologies, church leaders can waste time, spinning their wheels on technical fixes to problems, while ignoring the deeper issues that are involved. Though it can take years, but church leaders need to address the explicit and implicit theologies of their congregants.
To begin with, explicit theology is what a church expressly believes. Explicit theology is usually easier to determine because of its public nature. What a church explicitly believes can be gathered from mission and value statements, doctrinal position papers, sermons, liturgy (including the hymnody), and various other items that express belief. While explicit theology is often accurate, it can sometimes be more of an expression of intent, meaning that not everyone may hold to the same ideal. Even still, explicit theology is usually the starting point for understanding what a congregation believes.
Implicit theology, on the other hand, is underneath the surface per se, and for that reason, it is much more difficult to determine. The term implicit theology refers to those beliefs that are held, but may not be fully expressed. Peter Cha, for example, illustrated how difficult it is to interpret implicit theology from merely what is visibly seen (i.e., artifacts), and that church leaders must take time to question what is unseen. In fact, congregants themselves may not even be aware of their underlying beliefs until they are explicitly pointed out. Implicit theology can include anything from the pastor is the most spiritual man in our congregation to real worship means the raising of hands. In most contexts, neither of the statements would be verbalized, but they can become part of the working assumptions of a congregation.
As Kevin Ford points out in Transforming Church, churches function best when their explicit theology matches their implicit theology and vice versa. If there is any discontinuity between the two, there will be underlying conflict. Such conflict should not be overlooked, but used as an opportunity to change either explicit or implicit theology, so that it better aligns with Scripture. To help encourage spiritual transformation, therefore, church leaders should be aware of both explicit theology and implicit theology, so that churches can be healthier and more apt to grow.
As church leaders help to develop local churches, they must look beyond mere technical fixes and focus on deeper adaptive change. In this effort, however, church leaders must take time to delve into the basic assumptions of a congregation, compare those assumptions with Scripture, and invest time in changing unbiblical assumptions. Simply changing the explicit theology (such as a doctrinal statement) will not change peoples hearts. Ministry needs to go deeper than what is espoused, so that heart issues, including what is assumed, can be sanctified for Gods glory.
