Hello @fm107, I'm not sure if you still visit CF, but just in case, the following links may be helpful, particularly the ones that lead to the Westminster Standards.
PCA Constitutional Documents
The Constitution of the Presbyterian Church in America, which is subject to and subordinate to the Scriptures of the Old and New Testaments, the inerrant Word of God, consists of its doctrinal standards set forth in the Westminster Confession of Faith, together with the Larger (1-115; 116-196) and Shorter Catechisms, and the Book of Church Order, comprising the Form of Government, the Rules of Discipline and the Directory for Worship; all as adopted by the Church.
