The Bible is our Primary Standard.
The Bible alone is the inscripturated Word of God. Being divinely inspired it is the absolute authority as truth, inerrant and infallible in all matters. It is our final standard in all matters of faith and practice.
The Reformed Confessions are our Subordinate Standards.
The truths of Scripture are accurately expressed in the orthodox creeds of the early church (Nicea AD321; Constantinople AD381; Chalcedon AD451) and the historic creeds and confessions of the Protestant Reformation.
