Orthodox Presbyterian Church

Heritage

The Orthodox Presbyterian Church was constituted in June 1936 in Philadelphia by J. Gresham Machen and ministers who had been disciplined by the Presbyterian Church in the U.S.A. for founding an independent missions board in protest of modernism on the official one. Machen — Princeton New Testament scholar, author of Christianity and Liberalism, founder of Westminster Theological Seminary in 1929 — died within months, and the young church weathered an immediate split when Carl McIntire's fundamentalist wing departed in 1937. What remained set the OPC's enduring character: scholarly, confessional, unhurried about growth. RCMS 2020 counted 336 US congregations.

Theological family

Old School Westminster Calvinism: the inerrant Scriptures and the Westminster Confession and Catechisms subscribed with rigor; the OPC prizes the ordinary means of grace — Word, sacrament and prayer — over programs, and has produced theological writing far out of proportion to its size.

Who decides what

Presbyterian in full: congregations under sessions of elders, presbyteries, and a General Assembly whose decisions are reached with deliberate, sometimes glacial care; ministers are examined exactingly, and only men are ordained to office.

What a first-time visitor would find

Reverent, Word-saturated worship on the regulative principle: substantial expository preaching, congregational psalm and hymn singing, prayer with weight, and the Supper administered with seriousness. Programs are few; the means of grace are the program.

What it has always cared about

Doctrinal fidelity at the cost of size and standing; rigorous ministerial training in the Westminster Seminary orbit; presbyterian order actually practiced; and patient foreign missions — the OPC has sent scholars and missionaries alike since its first years.

Its gift to the wider church

The OPC preserved confessional Presbyterianism through the mainline's modernist century and handed the whole Reformed resurgence its textbooks — Machen's Christianity and Liberalism remains the classic statement of the issue, and the church's scholarly line (Van Til, Murray, and their students) trained generations far beyond its own pews.

Commonly confused with

Most stubbornly, with Eastern Orthodoxy — "Orthodox" here means confessionally orthodox Presbyterian, and this body is routinely misfiled as Eastern Orthodox in church data, including sources ours must correct against. Also with the PCA, its larger southern-born cousin: shared standards and warm relations, but the OPC is older (1936 vs. 1973), smaller, and generally stricter in subscription and worship; and with the Bible Presbyterian Church, which left it in 1937.

Range of views inside it

Range within strict bounds: psalmody-heavy versus hymn-mixed worship, degrees of subscriptionist strictness, and temperamental differences between scholarly and pietist strains — famous internal debates, invisible from the street.

Moments this body was part of

• 1922–1936 — The fundamentalist–modernist controversy

  Harry Emerson Fosdick's 1922 sermon "Shall the Fundamentalists Win?" lit a decade of struggle over Scripture, miracles and the creed inside the northern Presbyterian and Baptist churches. Conservatives lost the institutional fights and walked: J. Gresham Machen founded Westminster Seminary in 1929 and the Orthodox Presbyterian Church in 1936, Regular and Conservative Baptists formed their own associations, and a vast independent Bible-church movement grew outside every denomination.

  The argument was real and remains real — but the heirs of both sides now frequently pray, serve and plant together in the same cities, which nobody in 1925 predicted.
