“Evangelical” and “fundamentalist” are often used as though they mean conservative Christian I dislike.
Historically, the words have more precise stories.
They overlap. They are not identical.
Evangelical Is the Older Word
The word evangelical comes from the Greek-rooted language of the Gospel.
In Reformation Europe it could refer broadly to Protestant Christianity.
Later English-speaking evangelical movements emphasized themes such as conversion, biblical authority, Christ's saving work, evangelism, and active Christian life.
The evangelical revivals of the eighteenth and nineteenth centuries predate twentieth-century fundamentalism.
The Fundamentalist-Modernist Crisis
By the late nineteenth and early twentieth centuries, Protestant churches faced major disputes over biblical criticism, miracles, evolution, virgin birth, resurrection, supernatural revelation, and doctrine.
Theological modernists sought to reinterpret Christianity in light of modern intellectual currents.
Conservatives feared that the historic faith was being surrendered.
The Fundamentals
Between 1910 and 1915, a collection of essays titled The Fundamentals defended conservative Protestant doctrine.
The essays addressed biblical authority, Christ, atonement, resurrection, modern criticism, and theology.
The word fundamentalist soon became associated with Christians defending what they regarded as the fundamentals of the faith against modernism.
Were There Exactly Five Fundamentals?
Popular histories often speak of five fundamentals, commonly including biblical authority, virgin birth, substitutionary atonement, bodily resurrection, and second coming or miraculous reality.
Lists and formulations varied.
The Fundamentals themselves contained far more than five propositions.
It is safer to speak of a movement defending core supernatural Protestant orthodoxy.
J. Gresham Machen
J. Gresham Machen opposed theological liberalism but did not like being reduced to every cultural stereotype of fundamentalism.
His book Christianity and Liberalism argued that liberal Protestantism was not simply a different emphasis within Christianity but a fundamentally different religion.
Machen represents a crucial point: theological conservatism did not require every sociological feature later associated with fundamentalist subculture.
Separation
As modernists gained influence in some mainline institutions, many fundamentalists developed a strong theology of separation.
Believers should separate from churches and institutions that tolerated serious doctrinal error.
Some later fundamentalists developed secondary separation: separation not only from liberals but also from conservatives who cooperated with liberals.
This became one of the strongest sociological differences with postwar evangelicalism.
Neo-Evangelicalism
In the 1940s and 1950s, a new generation of conservative Protestants wanted to retain traditional doctrine while escaping anti-intellectualism, cultural isolation, endless separatism, and narrow institutionalism.
Figures such as Harold John Ockenga used language such as “new evangelicalism” or neo-evangelicalism.
The movement wanted engagement without theological surrender.
National Association of Evangelicals
The National Association of Evangelicals was organized in the 1940s.
It brought together conservative Protestant Christians who wanted cooperation in missions, public witness, education, and religious liberty.
The NAE represented an alternative both to theological liberalism and to stricter separatist fundamentalism.
Billy Graham
Billy Graham became the public face of postwar evangelicalism.
His crusades were strongly conversionist and biblically conservative.
But Graham cooperated with Christians across denominational lines.
Strict fundamentalists criticized this cooperation.
This conflict made the evangelical-fundamentalist divide much more visible.
Christianity Today
Founded in 1956, Christianity Today sought to provide an intellectually serious, culturally engaged voice for conservative evangelical Christianity.
Its early editorials explicitly wrestled with the relation between evangelicalism and fundamentalism.
The publication represents the postwar attempt to maintain doctrinal orthodoxy without retreating from public intellectual life.
Doctrine: Large Overlap
Historically, many fundamentalists and evangelicals share belief in Trinity, deity of Christ, virgin birth, Cross, bodily resurrection, biblical authority, conversion, and evangelism.
So the difference is not usually Christians versus non-Christians.
It is often about boundaries, cooperation, culture, scholarship, church separation, and methods.
Scripture
Both movements have traditionally emphasized biblical authority.
Twentieth-century evangelicals developed sophisticated debates over inspiration, inerrancy, infallibility, genre, and interpretation.
Some fundamentalists treated particular Bible translations or interpretive traditions as identity markers.
But one should not project the most extreme positions onto all fundamentalists.
Science and Education
Fundamentalism became associated in public memory with conflict over evolution, especially the Scopes Trial.
Some fundamentalist institutions became anti-intellectual.
Others built serious colleges, seminaries, and publishing ministries.
Postwar evangelicals consciously invested in scholarship. Fuller Theological Seminary became a symbol of this effort.
Politics
Today evangelical is often treated as a political voting category.
That can obscure religious meaning.
Evangelicalism is global. African, Asian, Latin American, and European evangelicals cannot be reduced to American party politics.
Likewise fundamentalism has religious and historical meanings broader than political activism.
Are All Fundamentalists Evangelicals?
In a broad theological sense, many Christian fundamentalists belong to the evangelical family.
But sociologically they may reject the label evangelical because they view modern evangelical institutions as compromised.
Are All Evangelicals Fundamentalists?
No.
Many evangelicals consciously define themselves against fundamentalist separatism.
Others share conservative doctrine but differ in cultural engagement, academic posture, and ecumenical cooperation.
Orthodoxy's Perspective
Eastern Orthodoxy shares with conservative evangelicals and fundamentalists a defense of Trinity, Incarnation, miracles, bodily Resurrection, and objective Christian truth.
But Orthodoxy disagrees strongly with the Protestant assumptions underlying both movements concerning sola Scriptura, sacramental theology, apostolic tradition, and ecclesiology.
Thus Orthodox Christians can appreciate their defense of supernatural Christianity without treating either movement as a recovery of the whole ancient Church.
Final Verdict
Evangelicalism and fundamentalism overlap historically and doctrinally, but they are not synonyms.
Fundamentalism arose especially from the early twentieth-century fight against Protestant modernism.
Postwar evangelicalism retained much conservative doctrine while attempting to move beyond strict separatism, cultural retreat, and anti-intellectual tendencies.
The divide is therefore best summarized as:
shared concern for biblical and supernatural Christianity, combined with different strategies for church boundaries, cultural engagement, scholarship, and cooperation.
Modern political usage often obscures that history.
