Theologian Oliver Crisp:
As Christians, we believe Scripture is the norming norm, the ultimate basis for theological judgments. The catholic creeds of the first few centuries of the church are a secondary tier of norm that witnesses to Scripture. Then we have confessions that represent particular church bodies, like the 39 Articles of Anglicanism—which are very Reformed, I might add—and the Westminster Confession for Presbyterians. Confessions are a third tier of witness, norms that stand under Scripture and the catholic creeds. It seems to me the work of particular theologians are a step below the confessions, because confessions represent the common mind of a particular ecclesial body.
