Providence OPC holds to the historic doctrines of the Reformed Faith, believing that the Bible is the inerrant God-breathed Word of God. We worship the one true God, Father, Son and Holy Spirit, and we place our trust for salvation from sin in the atoning work of Jesus Christ. We hold to the Westminster Confession of Faith & Catechisms, faithful summaries of the Bible's teachings, as standards secondary only to Scripture. The Bible is the inspired written Word of God, without error in all that it teaches and commands, the only rule for doctrine, worship and life; Jesus Christ, God’s eternal Son, fully God and fully man, is the sovereign Lord over all of life and history, including our salvation, over nature, nations and the church, the only Savior from sin and the judge of all the world; All mankind descended from Adam, are lost in sin; and we sinners can be restored to God, forgiven and made new, only by a new birth from Him and faith in the Lord Jesus Christ for salvation. The O.P.C. is a member of the North American Presbyterian and Reformed Council( NAPARC) and of the International Conference of Reformed Churches (ICRC), but not of the National Council or the World Council of Churches. We have fellowship with other Reformed and Presbyterian Churches who are committed to the infallible Scriptures, and are members of NAPARC and ICRC.

Confession and Catechisms

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