What is the divine sense (sensus divinitatis) according to John Calvin, and does it resemble the concept of fiṭra in Islam?

This question lies at the heart of the discussion about innate religious knowledge. Calvin's concept of the divine sense and its comparison with Islamic fiṭra reveals deep similarities and subtle differences between the Protestant and Islamic traditions in understanding how humans know God.

Inadequate responses to avoid

From some Muslims: "Calvin's concept is borrowed from Islam" — a historical claim that requires evidence. "Islamic fiṭra is deeper and more comprehensive than any Christian concept" — a prejudgment that ignores the richness of Reformed theology.

From some Protestants: "The divine sense is a purely biblical concept, unrelated to Islam" — an avoidance of useful comparative dimensions. "Islamic fiṭra is primitive compared to Calvin's theological development" — unjustified superiority.

From some secularists: "Both are religious superstitions with no scientific basis" — a premature rejection of serious philosophical discussion about religious knowledge.

The Divine Sense according to John Calvin

In his foundational work "Institutes of the Christian Religion" (Institutio Christianae Religionis, 1536-1559), Calvin presents the concept of sensus divinitatis (divine sense):

Calvinian definition: A "religious seed" (semen religionis) implanted in every human, an innate knowledge of God's existence and authority. Not rational inference, but direct perception.

Characteristics according to Calvin:

1. Universal: present in all humans without exception
2. Innate: not acquired through learning or reasoning
3. Direct: produces immediate knowledge of God, not mere inclination
4. Limited: gives knowledge of God's existence and authority, but not his Trinitarian nature
5. Corrupted by sin: original sin has corrupted but not erased it

Its mechanism according to Calvin:

When encountering creation (nature, cosmic order, beauty), or in moments of danger or awe, this sense is activated and produces knowledge "that God exists" and "that I am accountable before him."

The Concept of Fiṭra in Islam

Fiṭra in Islamic tradition is a multidimensional concept, based on the prophetic hadith: "Every child is born upon fiṭra."

Main Islamic definitions:

1. According to classical exegetes: natural inclination toward monotheism
2. According to Ashʿarīs: capacity to accept Islam
3. According to Ibn Taymiyya: innate knowledge of God and of truth and falsehood
4. According to al-Ghazālī: divine light in the heart that distinguishes truth

Characteristics of fiṭra:

1. Original: humanity's first state before external influences
2. Comprehensive: includes monotheism and basic ethics
3. Susceptible to obscurement: environment and upbringing may conceal it
4. Susceptible to revival: revelation and reminders awaken it

Similarities between the concepts

Universal innate character: Both affirm that every human is born with divine knowledge or inclination.

Independence from reasoning: Not the result of rational proof but a primary given.

Susceptibility to corruption: Both acknowledge that external influences (sin for Calvin, environment in Islam) may distort it.

Need for revelation: Despite its existence, both see revelation as necessary for complete knowledge.

Normative function: Both make it the basis for religious responsibility.

Important differences

Cognitive content:
- Calvin's divine sense: knowledge of God's existence and authority only
- Islamic fiṭra: broader, includes monotheism and basic moral inclinations

Degree of corruption:
- For Calvin: severely corrupted due to the Fall, needs special grace for restoration
- In Islam: obscured but not essentially corrupted, revivable through reminder

Relationship to salvation:
- For Calvin: insufficient for salvation, requires faith in Christ
- In Islam: basis of moral obligation, return to it is possible

Theological nature:
- Calvin: part of very limited natural theology
- Islam: part of the eternal covenant (ʿālam al-dharr)

Contemporary developments

In contemporary Reformed philosophy:

Alvin Plantinga developed Calvin's concept in "Reformed Epistemology." For him, the divine sense is a cognitive faculty that produces properly basic beliefs about God. This development made the concept more amenable to contemporary philosophical discussion.

In contemporary Islamic thought:

Thinkers like Taha Abd al-Rahman and Hassan Hanafi have reread fiṭra in light of contemporary philosophy. Some compare it to Kantian moral consciousness, others to religious experience in Schleiermacher.

Points of convergence in contemporary discussion

Common challenge: How do we defend the reasonableness of innate religious knowledge in an age of naturalism?

Similar strategies:
- Affirming it as basic knowledge requiring no proof
- Connecting it to deep human experiences
- Explaining religious diversity despite one fiṭra/sense

Common criticism they face:
- Scientific challenge: Does it have a neurological/psychological basis?
- Diversity challenge: Why does it produce different religions?
- Epistemological challenge: How do we distinguish true fiṭra from illusion?

Significance for contemporary discussion

Both concepts offer important contributions to discussions about:

1. Origin of religion: Is religion innate or acquired?
2. Religious knowledge: Can God be known without revelation?
3. Religious pluralism: How do we explain diversity despite shared fiṭra?
4. Relationship between faith and reason: Is religious knowledge rational?

Where we stand in this discussion today

The comparison between the divine sense and fiṭra reveals deep commonalities between the two traditions. Both affirm an innate dimension in religious knowledge, even if they differ in details. This similarity opens possibilities for constructive dialogue between religious traditions about the nature of religious knowledge and its role in human life.

From a "rational preponderance" (rajḥān ʿaqlī) perspective, the existence of similar concepts in independent traditions may strengthen the cumulative reasonableness of the claim that there is a genuine innate dimension in human religious experience.
