Christian Clarity in Relation to Islam: A Pastoral and Doctrinal Reflection

Preamble

The One Catholic Church, entrusted with the deposit of faith and the care of souls, finds herself increasingly called to navigate complex interreligious grounds. Among these, the relationship between Christianity and Islam demands particular attention—not solely for its theological implications, but for the pastoral and cultural challenges it presents to Christian communities across the World.

This document arises from a spirit of fidelity to Christ and concern for ecclesial integrity. It seeks not confrontation, but discernment, not polemics, but proclamation. In addressing the substantial differences between the doctrines of the Church and those upheld within Islamic traditions, the aim is not to vilify, but to clarify. Clarity is not the enemy of charity—indeed, it is its condition.

At a time when secular and political relativism threatens to flatten distinct voices into a haze of interfaith ambiguity, the Church must speak with courage. Such speech is not a reaction against others, but a renewal of her own vocation: to proclaim the Word made flesh, crucified and risen, in season and out of season.

May those who read these reflections—bishops, theologians, catechists, politicians and lay faithful—find here a tool for deeper understanding, renewed missionary confidence, and faithful engagement with both the challenges and opportunities of our religiously plural world.

Let us proceed, then, with minds illumined by the Spirit and hearts anchored in the Cross.

 

Islam and Christianity: Incompatible Doctrines, Divergent Ethos, and the Call to Vigilant Witness

A Theological and Socio-Cultural Assessment

I. Introduction

The contemporary global landscape calls for a renewed discernment of interreligious dynamics, particularly between Islam and Christianity—two of the world's most expansive and influential religions. While mutual respect and peaceful cohabitation remain possible in many contexts, theological and legal foundations intrinsic to Islam present serious incompatibilities with the Christian faith and pose significant challenges for Western societies rooted in Judeo-Christian values. This document aims to articulate, with scholarly precision and pastoral conviction, why Christianity and Islam diverge irreconcilably in doctrine, moral vision, and societal aspiration. Particular attention is given to Islamic denial of the Trinity and the divinity of Christ, Qur’anic hostility toward Jews and Christians, juridical impositions such as the jizya, and the broader aim of Shariah’s ascendancy.

II. Theological Irreconcilability: The Trinity and the Divinity of Christ

At the heart of Christianity lies the mystery of the Triune God and the Incarnation. Islam, however, explicitly denies both.

1. Rejection of the Trinity

The Qur’an states in Surah An-Nisa (4:171):

“Say not ‘Three’: desist—it will be better for you. Allah is but one God.”

And in Surah Al-Ma’idah (5:73):

“They surely disbelieve who say: Allah is the third of three.”

Islamic theology (tawhid) holds an uncompromising view of God’s oneness, and any notion of tri-unity is considered shirk (associationism), the gravest sin in Islam.

2. Rejection of Christ’s Divinity

Jesus is revered in Islam as a prophet, born of the Virgin Mary, but strictly not divine. The Qur’an in Surah Al-Ma’idah (5:116) records:

“And [on Judgment Day] Allah will say: O Jesus, son of Mary! Did you say unto mankind: ‘Take me and my mother for two gods besides Allah?’”

This directly challenges Christian claims regarding the divinity of Christ and the role of Mary as Theotokos (Mother of God), not as a deity.

3. Christian Doctrine

By contrast, Christianity affirms:

  • The Holy Trinity: one God in three persons (cf. Matthew 28:19).

  • The divinity of Christ (cf. John 1:1–14, Colossians 2:9).

  • Salvation through the Incarnation and Cross (cf. Philippians 2:5–11).

Thus, Islam and Christianity are not merely different—they present mutually exclusive claims about the nature of God, salvation, and divine revelation.

III. The Qur’anic Portrayal of Jews and Christians: Hostility and Exclusivity

While Islam acknowledges Jews and Christians as "People of the Book" (Ahl al-Kitab), this recognition does not equate to religious parity or peaceful coexistence. A significant portion of the Qur’anic corpus and classical tafsir (commentary) literature consistently adopts an adversarial posture towards Jews and Christians, especially when they refuse Islamic dominion or reject Muhammad as a prophet.

1. Waging War and Demanding Subjugation

Surah At-Tawbah (9:29):

“Fight those who do not believe in Allah or in the Last Day, and who do not consider unlawful what Allah and His Messenger have made unlawful—and who do not adopt the religion of truth—from those who were given the Scripture, until they pay the jizyah with willing submission and feel themselves subdued.”

This verse has historically served as the cornerstone for the Islamic doctrine of jihad against non-Muslims and the juridical imposition of jizyah, a tax representing public acknowledgement of Islamic supremacy.

Commentary:
Ibn Kathir, one of the most influential classical Qur'anic commentators, interprets this verse as a command to wage war against non-Muslims who reject Islam’s legal norms and refuse conversion, or at least submission. The requirement that Jews and Christians “feel themselves subdued” (wahum ṣāghirūn) is not merely fiscal—it is an explicit demand for social and political inferiority.

2. Exclusionary Allegiances

Surah Al-Ma’idah (5:51):

“O you who have believed, do not take the Jews and the Christians as allies. They are [in fact] allies of one another. And whoever is an ally to them among you—then indeed, he is [one] of them.”

Interpretive Context:

Al-Qurtubi, another preeminent medieval exegete, asserts that Muslims must never enter into genuine alliances or friendships with Jews and Christians, particularly in matters of governance or religious practice. This verse remains widely cited by Islamic fundamentalists to justify estrangement from pluralistic and democratic societies.

Surah Al-Imran (3:118):

“O you who have believed, do not take as intimates those other than yourselves, for they will not spare you [any] ruin. They wish you would have hardship.”

Here, the Qur’an presumes a latent hostility among non-Muslims, especially Jews and Christians, casting them as agents of sabotage and spiritual corruption.

3. Denunciation and Condemnation

Surah Al-Baqarah (2:120):

“Never will the Jews or the Christians be pleased with you until you follow their religion.”

This verse frames religious pluralism not as mutual respect, but as coercive competition. Islamic orthodoxy, therefore, emphasises resistance to non-Muslim religious systems as inherently incompatible with divine truth.

Summary of Implications

Taken cumulatively, these verses—reinforced by authoritative tafsir and juridical consensus—illustrate a religious worldview that positions Jews and Christians as obstinate, spiritually corrupt, and liable for punishment unless they submit to Islam’s sovereignty. Despite modern efforts at interfaith harmony, classical Islamic doctrine maintains a posture of exclusivism, coercion, and theological contempt toward these groups.

IV. Shariah Law and the Jizya: Submission, Segregation, and the Challenge in the West

In classical Islamic jurisprudence (fiqh), society is divided into distinct legal categories: Muslims, dhimmis (protected non-Muslims), and others who must be subdued through conquest. At the core of this legal stratification stands Shariah—Islamic divine law—and jizyah, a compulsory tax that embodies non-Muslim submission within Islamic governance. While contemporary Muslims in the West may argue for pluralistic adaptations, the foundational legal sources remain clear and uncompromising.

1. The Legal Framework of Shariah

Shariah derives from four primary sources: the Qur’an, the Sunnah (prophetic tradition), Ijma' (consensus), and Qiyas (analogical reasoning). It encompasses civil, criminal, and moral law and is not merely a personal ethic but a comprehensive legal system.

In traditional Islamic societies, Shariah:

  • Denies equal legal status to non-Muslims.

  • Enforces gender hierarchies (e.g., male guardianship, female submission, unequal inheritance).

  • Criminalises conversion from Islam (riddah), sometimes with capital punishment.

  • Prohibits public displays of other religions, Catholic processions for example.

  • Authorises corporal punishments such as amputation and flogging.

While modern reformers attempt to soften these mandates, prominent Islamic jurists like Yusuf al-Qaradawi have reaffirmed Shariah’s intrinsic supremacy and its goal to eventually displace secular law.

2. Imposition of the Jizya Tax

Surah At-Tawbah (9:29), as previously noted, commands Muslims to:

“…fight those… who do not adopt the religion of truth… until they pay the jizyah with willing submission and feel themselves subdued.”

The jizyah was historically levied on Jews, Christians, Zoroastrians, and others living under Islamic rule. It was more than a financial transaction—it symbolised inferiority, political disenfranchisement, and social segregation.

Classical Islamic Jurists’ Views:

  • Al-Mawardi (d. 1058) taught that jizyah confirms the subordination of non-Muslims and obliges their public humiliation.

  • Ibn Hazm emphasized that dhimmis must not bear arms, build new places of worship, or hold positions of influence over Muslims.

These prescriptions were codified in prominent legal schools such as the Hanbali, Maliki, and Shafi’i traditions.

3. Shariah Advocacy in the West

In recent decades, calls for Shariah-compliant tribunals have emerged in parts of Europe and North America, particularly within family law and financial services. While presented as cultural accommodation, such systems often:

  • Undermine the principle of legal equality.

  • Erode women’s rights, especially in inheritance, divorce and custody employment and work, equality and equity, etc.

  • Create communal enclaves resistant to integration.

  • Reinforce theological exclusivism and prevent genuine pluralism.

Example:
In 2008, Archbishop Rowan Williams ignited controversy by suggesting that limited Shariah accommodations might be inevitable in Britain. The backlash underscored public anxiety over religious legalism supplanting secular law. It must not happen. Ever.

 4. Political Implications

Islamic advocacy for Shariah in the West must be assessed not by contemporary apologetics but by reference to canonical sources. The Qur’an and Hadith do not envision a religious pluralism of equals, but a graduated hegemony where Islam reigns politically and juridically. The imposition of jizyah, the requirement that non-Muslims “feel themselves subdued,” and the prohibition of their civic parity indicate a framework unsuited to a liberal democratic ethos and the most essential principles governing Western Civilisation.

V. Sunan and Islamic Jurisprudence: Prescriptions for Infidels

The Sunan—collections of Prophetic traditions (ahadith)—form the bedrock of Islamic law alongside the Qur’an. These traditions are preserved in canonical compilations such as Sahih al-Bukhari, Sahih Muslim, Sunan Abu Dawud, and others. Across these sources, instructions concerning non-Muslims often reflect a framework of religious supremacy, social exclusion, and juridical restriction. Jurists in the classical period codified these principles into formal statutes governing Muslim interactions with "infidels"—a term broadly applied to unbelievers, especially Jews and Christians.

While the Qur’an sets forth the foundational vision of Islamic supremacy and conflict with non-believers, it is through the Sunan—collections of Hadith, or sayings and actions of the Prophet Muhammad—that Islamic jurisprudence derives its detailed prescriptions for interacting with Jews and Christians. These texts are essential in shaping the application of Shariah and have historically fostered a legal culture of religious stratification and exclusion.

1. Prohibition of Interreligious Friendship and Imitation

Sahih al-Bukhari, Book 78, Hadith 84:

“The Prophet said, 'Whoever imitates a people is one of them.'”

This hadith has been widely interpreted by classical scholars to forbid Muslims from adopting non-Muslim customs, particularly in dress, religious celebration, or civic practice. Imitation is viewed as symbolic alignment, and hence, apostasy or moral compromise.

2. Restrictive Social Norms

Sahih Muslim (Book 32, Hadith 6267):

“Do not greet the Jews and Christians before they greet you, and when you meet them on the road, force them to the narrowest part.”

This Hadith explicitly encourages social exclusion and humiliation of Jews and Christians, a command reaffirmed by classical jurists such as Imam al-Nawawi, who upheld its binding status for interpersonal etiquette within Muslim societies.

 Sahih Bukhari (Vol. 1, Book 11, Hadith 585) recounts:

“Allah's Messenger said, ‘I will expel the Jews and Christians from the Arabian Peninsula and will not leave any but Muslims.’”

This statement has been applied to justify the prohibition of non-Muslim religious institutions and buildings (churches, synagogues) in specific Islamic territories and enforces the concept of territorial purity based on religious identity.

3. Legal Disenfranchisement

Position of Dhimmi (non-Muslim) under classical law:

  • Cannot testify against Muslims in court.

  • Forbidden to carry arms or ride horses with a saddle.

  • Required to dress distinctly, often in humbling fashion.

  • Barred from public religious expressions, including bells, crosses, or processions.

Al-Kharaji’s Commentary on the Ahkam Ahl al-Dhimma articulates the purpose:

“They must know their place, and the dignity of Islam must be preserved.”

Such jurisprudence serves not merely as regulation but as codified degradation, aimed at reinforcing Muslim superiority and non-Muslim inferiority.

4. Military Jihad and Expansion

Sahih Bukhari (Vol. 4, Book 52, Hadith 220):

“The Prophet said: ‘I have been made victorious with terror.’”

Though debated in terms of interpretation, this Hadith has often been cited by militant groups to justify violence and intimidation as sanctioned tools of Islamic expansion.

Surah Al-Anfal (8:12) also declares:

“I will cast terror into the hearts of those who disbelieve. So strike them upon the necks and strike from them every fingertip.”

Taken in tandem with Hadith traditions, these verses form the scriptural scaffolding for theological violence aimed at non-Muslim populations, particularly when Islam is politically ascendant.

VI. Christian Response to Islamic Supremacist Ideology: Truth, Dignity, and Pastoral Presence

In confronting the ideologies detailed in earlier sections, the Christian response must be neither reactionary nor naive. It must blend theological clarity with incarnational compassion—rejecting falsehoods while embodying the luminous truth of Christ.

1. Affirmation of Universal Dignity

Genesis 1:27 declares:

“So God created man in his own image, in the image of God he created him; male and female he created them.”

This foundational verse asserts the radical equality and sacredness of all people, regardless of creed or culture. In Christian anthropology, there is no gradation of human worth—no grounds for subjugation or exclusion. Every person bears the Imago Dei, and thus every form of degradation, as found in the jurisprudence of dhimmi status, is a violation of divine justice.

2. Christocentric Compassion and Strength

Luke 10:30–37 (The Good Samaritan) reverses ethno-religious animus:

“But a Samaritan, as he journeyed, came to where he was, and when he saw him, he had compassion…”

Here, Jesus extols the charity of the religious outsider above the indifference of the religious elite. This parable becomes a prophetic model: Christians must resist retaliatory contempt and instead respond with restorative mercy—even toward those who degrade or exclude them.

Romans 12:21 encourages:

“Do not be overcome by evil, but overcome evil with good.”

This is not passivity—it is spiritual defiance. Christians, especially in regions where Islamic supremacism is operationalised, must bear witness through steadfast love and moral courage.

3. Political and Ecclesial Response

  • Pastoral solidarity: Churches must stand with the persecuted, offering sanctuary, advocacy, and spiritual accompaniment—modelled after the early Church’s boldness under Rome.

  • Interfaith engagement: Without compromise, Christians can engage Muslim thinkers who denounce supremacism and affirm human dignity, fostering alliances for peace.

  • Public proclamation: Where Shariah-inspired marginalisation is implemented, Christian leaders must resist publicly, not only with theological rebuttal, but with legal appeals, media witness, and ecumenical solidarity.

St. John Paul II wrote:

“To proclaim Christ is not to exclude; it is to include all in His redeeming love.”

4. A Eucharistic Antidote

Christian resistance is not merely challenging—it is mystical. The Eucharist, as the sacrament of unity, becomes the heart of the Christian counter-narrative to supremacism.

  • It erases religious stratification: all kneel equally before Christ.

  • It enacts radical hospitality: even persecutors may one day approach the altar.

  • It reveals suffering as redemptive: persecution is united to the Holy Cross.

VII. Conclusion: Vigilance and the Vocation of Christian Clarity

The preceding sections have revealed not merely doctrinal divergence between Christianity and Islam but an ethos of incompatibility. Christianity, grounded in the Incarnation and Eucharistic hospitality, confesses a God who suffers with and for the world. Islam, on the other hand, in its classical expressions, articulates a legal supremacism wherein political dominion and religious subjugation of non-Muslims are not accidental, but divinely mandated.

While contemporary reformist voices within Islam deserve encouragement, the weight of canonical texts - Qur’anic verses, Hadith traditions, and the centuries of juridical consensus - exposes the difficulty of reconciling Islam's foundational claims with the pluralist and sacramental vision of the One Catholic Church.

1. Ecclesial Strategy

In light of this, the Catholic Church must enact a threefold response:

  • Doctrinal Frankness: Avoid vague appeals to "shared Abrahamic values" when these conceal irreconcilable soteriological and Christological claims. Bishops and theologians must teach with precision, especially in formation contexts, ensuring that Catholic identity remains distinct and uncompromised. For example, Abraham is portrayed in the Qur’an as a Muslim, as is the case with Moses and even Jesus. It is therefore that historical Truth and Doctrinal integrity are preserved, regardless of the implications to ‘political correctness’.

  • Pastoral Vigilance: Support Christians living under Shariah regimes or in Western settings where Islamic legal or cultural pressure is mounting. The Church’s witness is not merely theoretical—it must express solidarity in suffering and speak with moral authority in civic and public governance political dialogue.

  • Apologetic Renewal: Develop educational and evangelistic materials that explain the Divinity of Christ, the Holy Trinity, and Christian Anthropology in ways that respond directly to Islamic objections. The mystery of the Cross must be proclaimed not only with beauty, but also with theological rigour.

2. Cultural Engagement

The challenge is not solely religious—it is cultural. The expansion of Islamic jurisprudence in the West, often under the mask of multicultural accommodation, risks undermining core principles of legal equality, religious liberty, and human dignity. Catholics must engage lawmakers, educators, and media voices with confident witness—not reactive rhetoric, but incarnational clarity rooted in the Gospel.

Gaudium et Spes (para. 76) reminds us:

“The Church and the political community, in their own fields, are autonomous and independent of each other. Yet both are devoted to the personal and social vocation of the same men.”

That vocation is threatened where supremacist ideologies, however wrapped in cultural appeal, seek domination over conscience.

Exhortation

Christian witness in this generation must embody the courage of martyrs and the charity of saints. We do not merely refute falsehood; we proclaim the Truth, Jesus Christ, Crucified and Risen. The Church must be a sanctuary of clarity, guarding her sacred deposit and forming the faithful for public engagement marked by dignity, resolve, and peace.

 To echo the words of St. Peter:

 “Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have, but do so with gentleness and respect.” (1 Peter 3:15)
