Presbyterian Understanding and Use of Holy Scripture

That Holy Scripture is the "rule of faith and life" is a basic principle of the Reformation. This confessional affirmation, in some formulation, is structural element of all the Reformed confessions.  It is stated and developed in the introductory chapter of the Westminster Confession of Faith.  Therefore, we might be inclined to assume that it represents a focal point of unity, a sign of commonality, among Presbyterians who are heirs of this Reformed tradition.
