That the Scriptures of the Old and New Testaments are the Word of God written and thus the only infallible rule of faith and life is the confession of the church and the belief of every minister, elder, and deacon. Further, we understand that there is a system of truth taught in Holy Scripture. It is the position of the church that the Westminster Confession of Faith and Catechisms, being founded upon and agreeable to the Word of God, set forth that system of truth; and every office-bearer acknowledges that Westminster Confession of Faith and Catechisms express his understanding of the system of truth which the Scriptures teach.
In speaking of a system of truth, we are saying that Scripture teaches both what we are to believe and what we are to do. Truth covers doctrine and ethics, faith and practice.
In speaking of the Westminster Confession of Faith and Catechisms (Larger and Shorter) together, we are saying that the Westminster system of faith and practice sets forth the system of truth taught in Scripture. The Westminster system is the wording of Confession of Faith complemented by that of Catechisms. Sometimes the Catechisms supplement what is said in the Confession; sometimes they summarise it; sometimes they restate it in other terms, fleshing out its meaning.
We use the text of the Westminster Confession of Faith which was approved by the Church of Scotland in 1647.
