The Orthodox Presbyterian Church stands in the line of historic orthodox Christianity. Our creed (“credo” is Latin for “I believe”), the Westminster Confession of Faith (see link below), was written in 1647 and is held by most Bible-believing Presbyterian denominations throughout the world. This creed defines our Presbyterian distinctives but also lays out our positions on the fundamental doctrines of Christianity. It adopts the positions that the early church hammered out in the early Church Councils (Nicea, A.D. 325; Constantinople, 381: Ephesus, 431; Chalcedon, 451) on the doctrines of the Trinity, deity of Jesus Christ, and the personality of the Holy Spirit. It also states our Protestant positions: that salvation is by grace alone through faith alone in Christ alone for the glory of God alone, and that the Bible alone is the infallible rule of faith and practice.
