Grace Presbyterian Church is a congregation of the Presbyterian Church in America. As such, we hold to a set of beliefs contained in the confessions, catechisms, and other doctrinal standards adopted by the Church....
We hold these standards and documents to be subject to and subordinate to the Scriptures of the Old and New Testaments, the inerrant Word Of God. The PCA has adopted a constitution which consists of its doctrinal standards set forth in the Westminster Confession of Faith, together with the Larger and Shorter Catechisms, and the Book of Church Order, comprising the Form of Government, the Rules of Discipline, and the Directory for Worship.
A good general description of what we as Reformed and Prebyterian Christians believe, please read this short document - What Presbyterians Believe.
