The OPC (Orthodox Presbyterian Church) is a part of the broader Christian church and traces its history back to the Protestant Reformation in the 1500s. As a denomination and as a local church, we believe that Bibical Christianity has been best summarized by the Westminster Confession & Catechisms. A brief summary of what we believe can be stated in the five "solas" of the Protestant Reformation:
Scripture Alone (2 Timothy 3:16)
Only the Bible—God’s Word—has ultimate authority for our lives.
In Christ Alone (John 14:6)
Salvation from sin & death is only possible through Jesus Christ.
By Grace Alone (Ephesians 2:1-9)
God’s grace—his unearned favor—is the foundation for and cause of our salvation, not anything good in us.
Through Faith Alone (Galatians 2:16)
Faith - receiving & resting on Jesus for salvation - is alone the instrument of our salvation.
To God's Glory Alone (1 Timothy 1:17)
All that we do in life is to be directed to honoring and glorifying God as he teaches us in his Word.

Our mission is to fulfill Jesus’ great commission of Matthew 28:19 to “make disciples of all nations” by working to plant a faithful Reformed church here in Chambersburg. We are here to:
- Worship the Lord Jesus as he instructs in the Bible
- Encourage and build one another up in the love of Jesus
- Seek and reach the lost with the good news of salvation by faith in Jesus.
Covenant is a congregation of the Orthodox Presbyterian Church (OPC). We are committed to sound biblical Christianity, are rooted in the worship and doctrine of the Reformation, and eagerly pursue Jesus's command to make disciples of all nations.
The Orthodox Presbyterian Church was founded on June 11, 1936, in the aftermath of the fundamentalist-modernist controversy, under the leadership of J. Gresham Machen (longtime professor of New Testament at Princeton Theological Seminary, who also founded Westminster Theological Seminary in 1929). With the infiltration of theological liberalism, the mainline Presbyterian Church in the USA had departed from historic Christianity, including the rejection of doctrines such as the inspiration and authority of Scripture, the virgin birth of Christ, and the substitutionary atonement. Originally calling itself the Presbyterian Church of America, the young church was forced by the threat of a lawsuit to change its name in 1939, and it adopted the name Orthodox Presbyterian Church.
In nearly eight decades since its founding, the OPC has slowly grown to over 30,000 members in over 300 churches throughout the United States and Canada. It has been vigorous in its defense and propagation of the historic Reformed faith as expressed in the Westminster Confession of Faith and Catechisms. The church’s efforts in worldwide outreach are conducted largely through three denominational standing committees: foreign missions, home missions and church extension, and Christian education. The OPC recognizes other churches of like faith and practice and is a member of the North American Presbyterian and Reformed Council (NAPARC) and the International Conference of Reformed Churches (ICRC).
