Article by RC Sproul: Avoiding Theological Anarchy (original source while the creeds are norma normata (“a rule that is ruled”).

Historically, Christian creeds have included everything from brief affirmations to comprehensive statements. The earliest Christian creed is found in the New Testament, which declares, “Jesus is Lord.” The New Testament makes a somewhat cryptic statement about this affirmation, namely, that no one can make the statement except by the Holy Spirit. What are we to understand by this? On the one hand, the New Testament tells us that people can honor God with their lips while their hearts are far from Him. That is to say, people can recite creeds and make definitive affirmations of faith without truly believing those affirmations. So, then, why would the New Testament say that no one can make this confession save by the Holy Spirit? Perhaps it was because of the cost associated with making that creedal statement in the context of ancient Rome.

The loyalty oath required by Roman citizens to demonstrate their allegiance to the empire in general and to the emperor in particular was to say publicly, “Kaisar Kurios,” that is, “Caesar is lord.” In the first-century church, Christians bent over backward to be obedient to civil magistrates, including the oppressive measures of Caesar, and yet, when it came to making the public affirmation that Caesar is lord, Christians could not do so in good conscience. As a substitute for the phrase, “Caesar is lord,” the early Christians made their affirmation by saying, “Jesus is Lord.” To do that was to provoke the wrath of the Roman government, and in many cases, it cost the Christian his life. Therefore, people tended not to make that public affirmation unless they were moved by the Holy Spirit to do so. The simple creed, “Jesus is Lord,” or more full statements, such as the Apostles’ Creed give an outline of basic, essential teachings. The creeds summarize New Testament content.

The creeds also used that summary content to exclude the heretics of the fourth century. In the affirmation of the Nicene Creed, the church affirmed categorically its belief in the deity of Christ and in the doctrine of the Trinity. These affirmations were seen as essential truths of the Christian faith. They were essential because without inclusion of these truths, any claim to Christianity would be considered a false claim.

At the time of the Reformation, there was a proliferation of creeds as the Protestant community found it necessary, in the light and heat of the controversy of that time, to give definitive statements as to what they believed and how their faith differed from the Roman Catholic Church’s theology. Rome itself added her creedal statements at the Council of Trent in the middle of the sixteenth century as a response to the Protestant movement. But each Protestant group, such as the Lutherans, the Swiss Reformed, and Scottish Reformed, found it necessary to clarify the truths that they were affirming. This was made necessary, not only because of disagreements within Reformed parties, but also to clarify the Protestant position against frequent misrepresentations set forth by their Roman Catholic antagonists.

The seventeenth-century confessional statement known as the Westminster Confession is one of the most precise and comprehensive creedal statements growing out of the Reformation. It is a model of precision and biblical orthodoxy. However, because of its length and comprehensive dimension, it is difficult to find two advocates of the Westminster Confession who agree on every single precise point. Because of that, churches that use the Westminster Confession or other such confessions, usually limit requirements of adherence by an acknowledgment of “the system of doctrine contained within.” These later Protestant creeds not only intended to affirm what they regarded as essentials to Christianity, but specifically to clarify the details of the particular religious communion that would use such comprehensive confessions of faith.

In our day, there has been a strong antipathy emerging against confessions of any stripe or any degree. On the one hand, the relativism that has become pervasive in modern culture eschews any confession of absolute truth. Not only that, we have also seen a strong negative reaction against the rational and propositional nature of truth. Creedal statements are an attempt to show a coherent and unified understanding of the whole scope of Scripture. In that sense, they are brief statements of what we historically have called “systematic theology.” The idea of systematic theology assumes that everything that God says is coherent and not contradictory. So, though these creeds are not created out of pure rational speculation, nevertheless, they are written in such a way as to be intelligible and understood by the mind. Without such confessions, theological anarchy reigns in the church and in the world.
