Yes, theologians have commented extensively on the relationship between existentialism and sin. The commentary is generally divided into two camps: those who believe existentialism offers a profound psychological description of the human condition (and thus sin), and those who believe it fundamentally redefines or denies the biblical nature of sin.
Here is a breakdown of the major theological perspectives:
### 1. The "Sin as Despair" Framework (Kierkegaardian View)
Søren Kierkegaard, the "father of existentialism" and a devout Christian, explicitly linked existential anxiety to sin.
* Despair as Sin: In his work The Sickness Unto Death, Kierkegaard defines sin not primarily as breaking a rule, but as despair—a misrelation in the self. To Kierkegaard, despair is the refusal to be oneself before God, or the desire to be someone other than who God created.
* Alignment: For Christian existentialists, this view aligns closely with the doctrine of sin. Sin is viewed as an existential state of alienation from one's true self and from God, rather than just a list of moral infractions.
### 2. The Neo-Orthodox View (Barth and Bultmann)
In the 20th century, theologians like Karl Barth and Rudolf Bultmann used existentialist categories (specifically from Martin Heidegger) to explain sin.
* Inauthenticity: They argued that sin is living "inauthentically"—clinging to worldly security, status, or self-justification rather than trusting in God's grace.
* Original Sin Redefined: As noted by critics, these theologians often redefined "original sin" not as a hereditary guilt, but as the universal human condition of finitude, mortality, and the inability to save oneself.
* Critique: Critics argue this reduces sin from a moral rebellion against a holy God to a mere psychological limitation or "mistake" of existence.
### 3. The Conservative/Evangelical Critique (Sin as Rebellion)
Many conservative and Reformed theologians argue that existentialism is misaligned with biblical teachings on sin because it shifts the focus from God to the self.
* Subjectivity vs. Objective Law: Critics like J. Ligon Duncan III argue that historic Christianity views sin as breaking God's law and rebelling against His sovereign will. Existentialism, by contrast, frames sin as betraying a relationship or failing to achieve personal authenticity.
* Autonomy as the Root of Sin: Critics argue that existentialism’s core value—radical individual autonomy and the creation of one's own meaning—is actually the definition of sin. In this view, the existentialist desire to define oneself is the same pride that caused the Fall in Genesis.
* Denial of Guilt: Some theologians argue that by focusing on "anxiety" and "angst," existentialism turns sin into a mental health issue or a philosophical predicament, thereby removing the objective guilt that requires penal substitutionary atonement.
### 4. The Atheist Existentialist "Alignment" (Sartre and Nietzsche)
While not theologians, these philosophers are often cited in theological discussions because they agreed with the religious diagnosis of the human condition but rejected the cure.
* Condemned to be Free: Jean-Paul Sartre argued that humans are "condemned to be free." Theologians often point out that this "angst" of total responsibility is exactly what the Bible describes as the burden of sin—being cut off from God and forced to bear the weight of one's own existence.
* Nihilism: Some theologians argue that atheistic existentialism is the result of sin. By rejecting God, humanity enters a state of meaninglessness and alienation, which existentialism accurately describes but fails to solve.
### Summary Table
| Perspective | Is Existentialism Aligned with Sin? | Key Argument |
| :--- | :--- | :--- |
| Kierkegaardian | Yes (Descriptive) | Sin is the existential state of despair and misrelation to God. |
| Neo-Orthodox | Yes (Reinterpretive) | Sin is "inauthenticity" and self-reliance; existentialism explains the human predicament. |
| Conservative | No (Conflict) | Existentialism denies objective moral law and elevates human autonomy, which is the essence of sin. |
| Atheist | Yes (Diagnostic) | Existentialism accurately describes the misery of the human condition (sin) but rejects the divine solution. |
### Conclusion
Most theologians agree that existentialism provides a powerful diagnosis of the human condition (anxiety, alienation, despair). However, they disagree sharply on whether that diagnosis is theologically sound.
* Progressive/Continental theologians generally see existentialism as a helpful tool for explaining what sin feels like and how it traps the self.
* Conservative/Evangelical theologians generally see existentialism as a philosophical manifestation of sin itself, arguing that it elevates the human subject to the place of God.
