The Soul of Abraham Lincoln

In Short

William E. Barton offers a rigorous, critical investigation into Abraham Lincoln's spiritual journey, seeking to rescue the president's memory from both pious hagiographers and aggressive secularists. Beginning with the primitive frontier churches of Kentucky and Indiana, the narrative traces Lincoln’s passage from youthful skepticism in New Salem to a mature, highly personal faith formed during the trials of the Civil War. Barton examines historical claims, letters, and contemporary testimonials to demonstrate how Lincoln’s religious views developed in step with his political duties. The work endures because it moves past partisan polemics to present a balanced, evidence-based portrait of Lincoln's complex inner life.

The Story

The book opens by establishing the fractured landscape of post-Civil War biography. Immediately following Lincoln's assassination, writers split into opposing camps: early biographers like J. G. Holland framed him as a orthodox Christian, while former law partner William Herndon and Ward Hill Lamon emphasized his early infidelity and rejection of traditional dogma. Barton positions his study as a dispassionate intervention, aiming to separate historical fact from polemical distortion by re-examining the primary evidence.

To understand Lincoln's spiritual foundation, the author reconstructs the religious atmosphere of his youth. Raised among the hardscrabble pioneer settlements of Kentucky and Indiana, Lincoln experienced church services in crude log meeting-houses. These gatherings featured unlettered but impassioned frontier preachers who used vivid imagery of heaven and hell to stir uneducated congregations. While Lincoln absorbed the moral seriousness and cadence of this environment—as well as a deep familiarity with the Scriptures—he remained detached from its emotional excesses and strict denominational boundaries.

As a young lawyer in New Salem and early Springfield, Lincoln entered a period of overt rationalism and intellectual revolt. Influenced by the writings of Thomas Paine and Volney, as well as Robert Chambers's evolutionary text Vestiges of the Natural History of Creation, Lincoln openly debated scripture and even penned an essay challenging orthodox doctrines, which friends reportedly burned to protect his political future. Barton addresses this controversial "infidel" period directly, assessing testimonies from contemporaries like James H. Matheny to confirm that young Lincoln held deep doubts regarding traditional theology and the literal truth of the Bible.

However, Barton demonstrates that Lincoln’s skepticism was not static. As he faced personal tragedy—such as the loss of his children—and took on heavy public responsibilities, his views underwent a subtle, profound transformation. In Springfield, exposure to thoughtful pastors like Dr. James Smith introduced him to intellectual defenses of Christianity. Although Lincoln never formally joined any church or signed a creed, he increasingly adopted a providential view of history, seeing human events as subject to the divine will.

This spiritual evolution culminated during his presidency. Confronted by the horrors of the Civil War, Lincoln relied heavily on a belief in an overruling God. His private reflections and public state papers, including his Thanksgiving proclamations and the Second Inaugural Address, reflected a deep, non-denominational piety rooted in divine justice and fatalistic trust. In key moments—such as his decision to issue the Emancipation Proclamation—Lincoln described himself as fulfilling a solemn vow to God. Barton ends the narrative by showing how the early skeptic became a leader whose mature worldview integrated scientific reason, moral justice, and profound religious faith.

How It Unfolds

The frontier crucible Lincoln grows up in the rustic frontier environment of Kentucky and Indiana, attending primitive log meeting-houses with rough puncheon benches and untutored, emotional preachers. These early experiences instill in him a lifelong familiarity with Biblical language, even as he remains outside formal church membership.

The rationalist revolt In New Salem and early Springfield, young Lincoln embraces intellectual skepticism, reading Thomas Paine and discussing arguments against orthodox theology with local wits. He writes a controversial manuscript questioning traditional doctrine, earning a local reputation for free-thinking rationalism.

The broadening mind Through books like Robert Chambers's Vestiges of the Natural History of Creation, Lincoln discovers that scientific concepts like evolution can coexist with belief in God. Dialogues with educated ministers in Springfield further soften his opposition to Christian evidences.

The burden of leadership As President, faced with national strife and personal tragedy, Lincoln shifts from abstract fatalism to an active, daily dependence on Providence. He attends Dr. Gurley's church in Washington and increasingly frames the Civil War as a divine chastisement for the sin of slavery.

The sacred vow Lincoln links his major political actions directly to his evolving sense of divine duty, declaring to his Cabinet that the Emancipation Proclamation is the fulfillment of a covenant made with God following the Battle of Antietam.

The People

• Abraham Lincoln: The central figure whose inner life is meticulously analyzed. He begins as a frontier youth steeped in rustic preaching, develops into a sharp young attorney with strong rationalist doubts, and ultimately emerges as a wartime leader whose deeply felt, non-creedally bound faith guides his national decisions.
• Thomas and Nancy Hanks Lincoln: Lincoln's parents, who embody the primitive, pioneer religious life of the early nineteenth century. Their participation in Baptist church services provides the initial backdrop against which Lincoln’s early intellect forms.
• William H. Herndon: Lincoln's long-time Springfield law partner and biographer. He vigorously argues that Lincoln remained an "infidel" throughout his life, serving as the chief proponent of the secular view that Barton critically re-evaluates.
• Dr. Newton Bateman: The Illinois Superintendent of Public Instruction, whose private 1860 conversation with Lincoln regarding the anti-slavery vote of Springfield ministers becomes a focal point of fierce biographical debate between early commentators.
• Robert Chambers: The anonymous author of Vestiges of the Natural History of Creation, whose work introduces Lincoln to evolutionary thought within a framework that preserves belief in a divine creator.
• Dr. Phineas D. Gurley: Pastor of the New York Avenue Presbyterian Church in Washington, D.C., who serves as Lincoln's spiritual counselor and pastor during his presidency.

In Its Own Voice

"The fact that there are so many books on the religion of Abraham Lincoln is a chief reason why there should be one more."

Barton opens his study by explaining why a critical, dispassionate analysis is necessary amid decades of partisan debate.

"'God, and Eternity, and Heaven were very near to me today.'"

Lincoln reflects on his dual role as attorney and pastor after reciting hymns to comfort a dying woman in a rural farmhouse.

"He learned of evolution, and was convinced of its truth, from a book whose spirit and purpose was to present the view in harmony with the Christian faith."

Barton highlights how reading Robert Chambers helped Lincoln reconcile scientific progress with a belief in God.

What It's Really About

• The Soul of Abraham Lincoln* is fundamentally an investigation into the nature of personal belief and intellectual integrity. It explores how a rigorous, questioning mind can reject institutional dogma without abandoning moral seriousness or spiritual faith. Barton argues that Lincoln’s religious views cannot be neatly categorized by traditional denominational labels or simple assertions of orthodoxy versus atheism. Instead, the book demonstrates how Lincoln synthesized early frontier influences, 19th-century scientific rationalism, and a profound sense of historical destiny. Ultimately, the work asserts that Lincoln’s true spiritual life was defined not by formal creeds, but by a developing moral commitment to justice, humility, and the belief that human history is guided by an overruling Divine Will.
