Remember, even the selection of specific texts of the Bible to show what we believe involves a certain amount of interpretation. If formulating creeds was wrong, then our behavior and doctrine could not be examined and corrected by the objective standard of God's revelation. We could not be helped by the advice and encouragement of other believers. All men have creeds, written or not. If not written, then it is difficult to examine beliefs for agreement with the Bible.
Unwritten creeds tend to contribute to confusion and heresy.
By setting clear boundaries written creeds and confessions help identify denials of Biblical authority and protect against elevating human ideas to equal standing with the Creator's truth as revealed. Good biblical statements unify the voice of the church and its teachers. Creeds and confessions should present a careful and sound summary of biblical ideas by which teachings and ideas can be examined. Officially adopted statements of the church's beliefs are Biblical. The published statement of the elders and apostles made it possible for believers to communicate accurately the advice of the council.
