The Westminster Standards
When the Presbyterian Church in the United States of America was formed in 1788, it adopted (with minor revisions) the Westminster Confession of Faith and the Larger and Shorter Catechisms (1647), as its secondary standards (the Bible itself being the only infallible rule of faith and practice). Officers in the Presbyterian Church in America take a vow to “sincerely receive and adopt” these confessional documents “as containing the system of doctrine taught in the Holy Scriptures.”
The following PDF documents contain the Confession and Catechisms with full Scripture proofs:
