The final authority for the faith and life of a historic Reformed Presbyterian church is the Bible. The Bible is a large book, however, and there are different interpretations of its message, even among evangelical Protestant Christians.
For that reason, it is not sufficient to simply declare that we believe the Bible is the Word of God. There is a need for summary statements of its teachings, which, although subordinate to the Bible itself, set forth the teachings of the Bible.
While most churches may have a simple, short, statement of faith, the statement of faith of Trinity Presbyterian Church is The Westminster Confession of Faith. All men in leadership positions at Trinity Presbyterian Church hold fast to this Confession as a summary statement of the truths of Scripture. The Westminster Confession of Faith may be accessed online at the Presbyterian Church of America.
