What is a Reformed church?
"Reformed" refers to churches whose theology traces directly to the Protestant Reformation of the 16th century — especially the work of John Calvin in Geneva, Switzerland, and John Knox in Scotland. Reformed theology is also called Calvinist theology, though many Reformed Christians prefer the former term.
In the United States, Reformed churches include Presbyterian congregations, the Reformed Church in America (RCA), the Christian Reformed Church (CRC), and many independent churches. The shared theological commitments — not a single denomination — define the movement.
The five points of Calvinism (TULIP)
The most recognizable summary of Reformed soteriology (the doctrine of salvation) is the "five points," often recalled by the acronym TULIP:
- Total depravity — sin has corrupted every part of human nature; no one seeks God apart from grace.
- Unconditional election — God chose who would be saved before creation, not based on foreseen faith or merit.
- Limited atonement — Christ's atoning death was specifically intended to save the elect (the "definite atonement" view).
- Irresistible grace — those whom God has chosen will inevitably come to faith; God's saving grace cannot ultimately be refused.
- Perseverance of the saints — true believers will persist in faith to the end; they cannot ultimately and finally fall away.
Not all people in Reformed churches hold all five points with the same firmness. Many are "4-point Calvinists" who hold a different view on limited atonement, and some simply identify with the broader Reformed tradition without rigidly affirming each point.
Reformed theology beyond TULIP
Reformed Christianity involves much more than five points about salvation. Other hallmarks include:
- Covenant theology — understanding the Bible as the story of God's successive covenants with humanity (Noah, Abraham, Moses, David, the New Covenant in Christ)
- The regulative principle of worship — corporate worship should include only what Scripture commands or implies, not whatever seems good; this has historically led to simple, Word-centered services in many Reformed churches
- Infant baptism — most (not all) Reformed churches baptize infants of believing parents as a sign of covenant membership, rather than waiting for personal confession of faith
- The sovereignty of God — a deep sense that God's governance extends to all things, including salvation
- Sphere sovereignty & cultural engagement — associated especially with Dutch Reformed thinkers like Abraham Kuyper, who famously said "there is not a square inch in the whole domain of our human existence over which Christ… does not cry: 'Mine!'"
Reformed denominations in the United States
- Presbyterian Church in America (PCA) — the largest conservative Reformed denomination in the US, with over 1,800 churches. Theologically conservative, historically Southern in roots.
- Orthodox Presbyterian Church (OPC) — founded in 1936 by J. Gresham Machen as a conservative alternative to mainline Presbyterianism; smaller but theologically rigorous.
- Reformed Church in America (RCA) — Dutch Reformed in heritage, one of the oldest denominations in North America; theologically centrist.
- Christian Reformed Church (CRC) — also Dutch Reformed, historically based in Michigan; strong in education and cultural engagement.
- United Reformed Churches in North America (URCNA) — conservative, confessionally Reformed; grew out of the CRC in the 1990s.
- Presbyterian Church USA (PCUSA) — the mainline Presbyterian body, theologically moderate to liberal; largest by membership but shrinking.
- Associate Reformed Presbyterian (ARP) — conservative, smaller; known for a cappella psalm-singing in some congregations.
Many independent Reformed churches exist outside these denominations. Look for keywords like "Reformed," "Calvinist," "confessional," or "covenantal" on a church's website to identify its theological commitments.
What to expect at a Reformed church service
Reformed worship tends to be Word-centered and often somewhat formal, though this varies widely. Common features include:
- Scripture reading — often extended, sometimes from both Old and New Testaments
- Expository preaching — detailed teaching through a passage or book of the Bible, often 35–50 minutes
- Congregational singing — traditional hymns, psalms, or contemporary worship songs depending on the congregation
- The Lord's Supper (Communion) — celebrated weekly in some congregations, monthly or quarterly in others
- Prayer — pastoral prayer and congregational prayer are emphasized
More traditional Reformed churches follow the liturgical elements of the Westminster Directory for Worship. Contemporary Reformed churches may use a praise band and projected lyrics while preaching the same theology as a centuries-old Reformed catechism.
Frequently asked questions
Is Presbyterian the same as Reformed?
Almost. Reformed and Presbyterian refer to the same theological tradition but emphasize different things: "Reformed" describes the theology (Calvinist); "Presbyterian" describes the church government (governed by elders, or presbyters). All Presbyterian churches are Reformed in theology, but some Reformed churches have congregational or episcopal governance rather than presbyterian.
Are Reformed churches evangelical?
Generally yes, especially PCA, OPC, and most independent Reformed churches. They hold the Bible as fully authoritative, emphasize personal conversion and saving faith, and prioritize evangelism. Some in the broader Reformed world use "evangelical" and "Reformed" interchangeably; others distinguish between the two movements.
What is the difference between Reformed and Lutheran?
Both are Protestant traditions from the 16th-century Reformation, but they differ on several points: the Lord's Supper (Lutheran teaching of the real bodily presence of Christ vs. Reformed teaching of spiritual presence), predestination (Lutherans reject double predestination), the law in the life of a believer, and worship style. Both affirm justification by grace through faith alone.
