Scripture is our sole infallible rule of faith. To guide our interpretation we have additional standards, subordinate to Scripture, which present our beliefs in greater detail. These subordinate standards are the Westminster Confession of Faith, the Declaration of Faith Concerning Church and Nation and Living Faith. Also, as a part of the broader Reformed tradition we recognize the Second Helvetic Confession, Belgic Confession, Gallican Confession, and Heidelburg Catechism as parallel secondary standards.
While church leaders vow to uphold the doctrine of our subordinate standards “under the continual illumination and correction of the Holy Spirit speaking in the Scriptures”, church membership requires only a basic faith in Jesus Christ, in agreement with the Apostles’ Creed.
