Monergism

In an age of individualism and skeletel creeds or barebone statements of belief, the rich tradition of corporate confessions of faith provide a vital link to the church of ages past and the saints of all ages.

Creeds of Christendom - Name and Definition
by Philip Schaff

A Creed, or Rule of Faith, or Symbol, is a confession of faith for public use, or a form of words setting forth with authority certain articles of belief, which are regarded by the framers as necessary for salvation, or at least for the well-being of the Christian Church.

A creed may cover the whole ground of Christian doctrine and practice, or contain only such points as are deemed fundamental and sufficient, or as have been disputed. It may be declarative, or interrogative in form. It may be brief and popular (as the Apostles' and the Nicene Creeds), for general use in catechetical instruction and at baptism; or more elaborate and theological, for ministers and teachers, as a standard of public doctrine (the symbolical books of the Reformation period). In the latter case a confession of faith is always the result of dogmatic controversy, and more or less directly or indirectly polemical against opposing error. Each symbol bears the impress of its age, and the historical situation out of which it arose.

There is a development in the history of symbols. They assume a more definite shape with the progress of biblical and theological knowledge. They are mile-stones and finger-boards in the history of Christian doctrine. They embody the faith of generations, and the most valuable results of religious controversies. They still shape and regulate the theological thinking and public teaching of the churches of Christendom. They keep alive sectarian strifes and antagonisms, but they reveal also the underlying agreement, and foreshadow the possibility of future harmony.
