The Modern Era: Overview

Historical Theology

The Church in This Era

The eighteenth and nineteenth centuries form one of the most paradoxical periods in the history of the church. It was an age of both declension and vitality, of corrosive doubt and ardent faith — and often the two flourished side by side, sometimes within the same nation, the same city, even the same university faculty.

On the one hand, the Enlightenment unleashed a sustained intellectual assault on historic Christianity. Reason was enthroned as the measure of all things; revelation was put on trial. Deists trimmed God down to a distant clockmaker. Hume cast doubt on miracles, Kant relocated religion to the realm of practical morality, and Lessing dug a “broad, ugly ditch” between the accidental truths of history and the necessary truths of reason. By century’s end, a new academic discipline — higher criticism — had begun to dismantle the traditional understanding of Scripture, and a brilliant young Reformed preacher named Friedrich Schleiermacher would father a theology that relocated the seat of religious authority from the Word of God to the human heart.

On the other hand, the same era witnessed extraordinary spiritual awakening. The Great Awakenings swept through Britain and the American colonies. Jonathan Edwards, the finest theological mind America has produced, married revival fire to Reformed precision. Whitefield’s voice carried the gospel to tens of thousands in open fields. And out of this renewed zeal came the modern missionary movement — Carey to India, Judson to Burma, Livingstone and Taylor opening Africa and China to the gospel.

“I will build my church, and the gates of hell shall not prevail against it.” (Matthew 16:18)

This era tests that promise as few others have. And the promise holds.

Where We Are in the Story

We stand downstream of the Reformation and the great age of confession-building. The seventeenth century gave the church its mature Reformed standards — the Westminster Confession (1646), the Synod of Dort (1619), the Helvetic and Belgic confessions. The doctrinal architecture was, in large measure, complete.

The question of the modern era is not so much what the church believes but whether it may believe at all — whether, in an age of telescopes and textual variants, of Newtonian physics and Hegelian philosophy, the old confessions could still stand. The Enlightenment did not merely dispute particular doctrines; it challenged the very category of revealed truth.

The church answered in two registers. The pietist and revivalist register answered with the warmed heart and the converted life. The confessional and scholarly register, embodied above all at Princeton, answered with rigorous defense of the inspiration and authority of Scripture. Both were necessary; neither alone was sufficient.

Key Figures

Jonathan Edwards (1703–1758) — theologian of revival, the affections, and the sovereignty of God.
George Whitefield (1714–1770) — itinerant evangelist of the Awakening.
John and Charles Wesley (1703–1791; 1707–1788) — Arminian revivalists, founders of Methodism.
David Hume (1711–1776) and Immanuel Kant (1724–1804) — Enlightenment critics of revelation and miracle.
G. E. Lessing (1729–1781) — author of the “ugly ditch.”
Charles Finney (1792–1875) — revivalist of the Second Great Awakening, the “new measures.”
Friedrich Schleiermacher (1768–1834) — father of liberal theology.
Albrecht Ritschl (1822–1889) and Adolf von Harnack (1851–1930) — heirs of the liberal tradition.
Archibald Alexander, Charles Hodge, A. A. Hodge, B. B. Warfield — the Old Princeton theologians.
William Carey (1761–1834), Adoniram Judson, David Livingstone, Hudson Taylor — pioneers of modern missions.

Key Controversies and Developments

The defining tensions of the age include:

Reason versus revelation. Could the supernatural survive the bar of autonomous human reason?
The authority of Scripture. Higher criticism, the documentary hypothesis, and the quest for the historical Jesus put the Bible’s historicity and inspiration in question.
Genuine awakening versus manufactured revivalism. From Edwards’s careful discernment of the affections to Finney’s pragmatic “new measures,” the church wrestled over whether revival is God-wrought or man-engineered.
The relocation of religious authority. Schleiermacher’s turn to feeling, and the liberal trajectory it launched, redefined the nature of Christian faith itself.
The defense of orthodoxy. Old Princeton mounted a learned, confessional answer to criticism and Darwinism.
The Great Commission rediscovered. The missionary movement recovered the church’s calling to the nations.

Councils, Creeds, and Confessions

This era produced few new ecumenical confessions of the stature of Westminster; the confessional age was largely behind the church. Yet it was not without standards. The Methodist movement codified its doctrine in the Twenty-Five Articles. American Presbyterianism wrestled with subscription and revision of the Westminster Standards, including the 1788 American revisions on the civil magistrate. And toward the end of the period, Old Princeton’s Hodge–Warfield article on “Inspiration” (1881) functioned as a confessional landmark, sharpening the doctrine of inerrancy for the controversies to come.

What Was Settled — and What Was Left

What was settled: the Reformed faith demonstrated that it could meet the Enlightenment on its own ground without surrender. Edwards answered the philosophers; Princeton answered the critics. The missionary movement settled, in practice, that the gospel is for all nations.

What was left unsettled was the great question that would dominate the next century: would the institutional churches hold to the supernatural, confessional faith, or would they accommodate the spirit of the age? Schleiermacher’s heirs and Princeton’s heirs were on a collision course. The lines drawn here would erupt in the twentieth century as the Fundamentalist–Modernist controversy.

A Reformed Assessment

Reading this age providentially, we see the hand of God preserving His church in a time of unprecedented intellectual assault. The promise of Matthew 16:18 was not voided by Hume’s skepticism or Schleiermacher’s reconstruction.

Yet semper reformanda cuts both ways. The Reformed church must honestly confess that orthodoxy was sometimes defended with a brittleness that mistook every change for compromise, and that revivalism sometimes traded the means of grace for technique. We do not romanticize this era. We receive its faithful witnesses — Edwards, the Hodges, Warfield, Carey — with gratitude, and we learn even from its failures.

Lessons for the Church Today

The modern era teaches us that intellectual challenge is not to be feared but engaged — charitably, rigorously, and from a posture of confidence in the truth. It teaches that revival cannot be manufactured but must be sought from the sovereign God. It teaches that the relocation of authority from Scripture to experience, however well-intentioned, hollows out the gospel. And it teaches that the church’s health is measured not only in doctrine defended but in nations reached.
