What Do All Abrahamic Religions Have in Common?

Judaism is the oldest of the three Abrahamic faiths and, in many ways, the root from which the others grew. Several core commitments define what it shares with its sibling traditions.

Monotheism and the God of Abraham

The foundational Jewish confession is the Shema: "Hear, O Israel: the LORD our God, the LORD is one" (Deuteronomy 6:4). This uncompromising monotheism—worship of the single Creator who made covenant with Abraham, Isaac, and Jacob—is the bedrock shared across all three religions Quran 3:67. Abraham himself is revered in Judaism as the first patriarch, the man who left polytheistic Ur in response to divine call (Genesis 12:1–3).

Revealed Scripture

Judaism holds the Torah (the Five Books of Moses) as the primary divine revelation, supplemented by the Prophets (Nevi'im) and Writings (Ketuvim). The concept that God communicates authoritative guidance through written and oral text is central to all three traditions. Scholars like Moshe Halbertal, in his 1997 work People of the Book, argue that Judaism essentially invented the idea of a community defined by a sacred canon.

Prayer and Worship

Daily, structured prayer is obligatory in Judaism. The Shacharit, Mincha, and Ma'ariv services parallel the prayer disciplines found in Christianity and Islam. All three traditions insist that worship must be directed to God alone—no intermediary deity, no idol.

Divine Moral Law and Ethics

The 613 commandments (mitzvot) of the Torah establish a comprehensive ethical and ritual framework. The Ten Commandments (Exodus 20) are shared, in varying forms, by all three faiths. Justice (tzedek), care for the poor, and honesty in dealings are not optional add-ons but core divine requirements.

Prophets and Divine Intervention in History

Judaism recognizes a long line of prophets—Moses, Isaiah, Jeremiah, and others—through whom God spoke. The belief that God actively intervenes in human history (most paradigmatically in the Exodus) is shared across all three traditions.

Eschatology

While Jewish views on the afterlife are more varied and less systematized than in Christianity or Islam, mainstream Judaism does affirm concepts of resurrection (techiyat ha-meitim), divine judgment, and a messianic age. The Talmudic tractate Sanhedrin 90a explicitly links resurrection to Torah belief.

Christianity emerged from Second Temple Judaism in the first century CE and explicitly claims Abraham as a spiritual ancestor. Paul's letter to the Romans (chapter 4) argues at length that Abraham's faith—not just ethnic descent—is the model for all believers. This shared Abrahamic identity is a major point of commonality Quran 3:67.

Monotheism

Christianity affirms one God, the Creator of heaven and earth. The Nicene Creed (325 CE) opens: "We believe in one God, the Father Almighty, maker of heaven and earth." It's worth noting that Christianity's Trinitarian theology—Father, Son, and Holy Spirit as one God in three persons—is a significant point of disagreement with Judaism and Islam, both of which reject it as compromising monotheism. Still, Christianity insists it is monotheistic.

Revealed Scripture

Christians share the entire Hebrew Bible (received as the Old Testament) with Judaism and add the New Testament. The conviction that God speaks authoritatively through written scripture is fundamental to all three faiths. Theologian N.T. Wright has emphasized since the 1990s that the Christian canon is unintelligible without its Jewish scriptural roots.

Abraham as Spiritual Father

Paul writes in Galatians 3:29, "If you belong to Christ, then you are Abraham's seed, and heirs according to the promise." Christianity doesn't merely acknowledge Abraham historically; it claims his covenant promise as its own inheritance—a direct parallel to Jewish and Islamic veneration of the patriarch Quran 3:95.

Prayer, Worship, and Moral Law

Daily prayer, communal worship, and adherence to a divinely revealed moral code (rooted in the Ten Commandments) are central Christian practices. Jesus himself summarized the law as love of God and neighbor (Matthew 22:37–39), drawing directly from Deuteronomy and Leviticus.

Prophets and Eschatology

Christianity venerates the Hebrew prophets and adds its own apostolic voices. It strongly affirms bodily resurrection, final judgment, and eternal life—themes that resonate across all three traditions, even if the specifics differ sharply.

Islam explicitly positions itself as the restoration of the original, pure monotheism of Abraham—a claim made directly in the Quran. This makes the Abrahamic connection not just historical background but a theological cornerstone Quran 3:67.

Abraham as the Model Muslim

The Quran states plainly: "Abraham was neither a Jew nor a Christian, but he was one inclining toward truth, a Muslim [submitting to Allāh]. And he was not of the polytheists" Quran 3:67. Islam thus claims Abraham as the archetypal hanif—a pure monotheist who submitted entirely to God. The annual Hajj pilgrimage re-enacts events from Abraham's life, cementing this connection in ritual practice.

Strict Monotheism (Tawhid)

Islam's concept of tawhid—the absolute oneness and indivisibility of God—is perhaps the most uncompromising monotheism of the three. The Quran declares: "Indeed, the religion in the sight of Allāh is Islām" Quran 3:19, meaning complete submission to the one God. Shirk (associating partners with God) is considered the gravest sin, which is why Islam rejects the Christian Trinity.

Revealed Scripture and Prophets

Islam affirms that God sent scriptures to earlier communities—the Torah (Tawrat) to Moses, the Psalms (Zabur) to David, and the Gospel (Injil) to Jesus—before the final and complete revelation of the Quran to Muhammad. All three faiths thus share the conviction that God communicates through prophetic revelation and written scripture. Scholar Fazlur Rahman, in his 1980 work Major Themes of the Qur'an, highlights this continuity of prophetic tradition as central to Quranic self-understanding.

Prayer, Moral Law, and Judgment

The five daily prayers (salat), obligatory charity (zakat), fasting (sawm), and pilgrimage (hajj) all have structural parallels in Jewish and Christian practice. The Quran repeatedly calls believers to justice, honesty, and care for the poor—ethical demands shared across all three traditions. Belief in the Day of Judgment (Yawm al-Qiyama) and bodily resurrection is a non-negotiable article of Islamic faith, mirroring similar convictions in Judaism and Christianity.

The Religion of Abraham

The Quran instructs: "Say, 'Allāh has told the truth. So follow the religion of Abraham, inclining toward truth; and he was not of the polytheists'" Quran 3:95. This verse encapsulates Islam's self-understanding as the fulfillment—not merely one branch—of the Abrahamic heritage.

From the Qur’an’s account, the shared Abrahamic baseline relevant to Jews is that Abraham’s path was pure monotheism, free of polytheism, and believers are summoned to follow his upright way Quran 3:95. It also asserts that Abraham himself was not a Jew, signaling that Abrahamic devotion precedes later communal identities while still emphasizing exclusive worship of the one God Quran 3:67. The Qur’an further remarks that disagreements among the scriptural communities arose after knowledge had come, implying that the core monotheistic inheritance is prior to subsequent divisions Quran 3:19.

From the Qur’an’s perspective, what Christianity holds in common with other Abrahamic paths is the call to emulate Abraham’s exclusive devotion to God and rejection of polytheism, presented as the archetype for true religion Quran 3:95. It adds that Abraham was not a Christian, again situating Abrahamic faith prior to later community names while centering monotheism as the essence Quran 3:67. The text also observes that divisions among people of the scripture are a later development, underscoring that dispute does not erase the foundational Abrahamic core Quran 3:19.

Islam explicitly frames the commonality of Abrahamic faiths as submission to the one God and following Abraham’s upright way, rejecting all forms of polytheism Quran 3:95. It declares that the true religion before God is submission (islām) and notes that communal disputes emerged later among the people of scripture, after knowledge had come Quran 3:19. It also emphasizes that Abraham was not a Jew or a Christian but a pure monotheist, positioning him as the shared exemplar for sincere devotion to God Quran 3:67.
