Due to their independent inclinations, congregational churches can often find themselves cut off from the larger trends, the history, and the idiom of the universal church—whether by design or happenstance. In light of that danger, this paper will argue that the theological foundations of congregationalism align with and support the use of ecumenical creeds in an authoritative role within the local church. To support and make the argument for the use of ecumenical creeds in congregational churches, this paper will consider how the local church is situated in the institution of the universal church. Then, this paper will examine the theological foundations of congregationalism to determine how those foundations can support the authoritative use of the creeds. In a related section, the paper will evaluate the authority of Scripture in relation to the creeds. Penultimately, the paper will consider the use and rejection of the creeds. Finally, the paper addresses divergent doctrinal positions and potential counterarguments. Congregational churches can use their polity to disengage from the history and actions of other churches, or they can embrace and submit to the universal church’s shared theological affirmations. This paper will argue for the latter by promoting and applying a theological framework already present in congregationalism.
