What Does the Title 'Father' Mean in Christianity and in Islam?

Judaism does use 'Father' (Av) as a title for God, though less centrally than Christianity. The Hebrew Bible addresses God as Father in passages like Isaiah 63:16, where the prophet declares that God's fatherhood transcends even the patriarchs: Isaiah 63:16 This is a relational and covenantal fatherhood — God as creator, protector, and redeemer of Israel — not an ontological or trinitarian claim. The Talmud also distinguishes carefully between literal and metaphorical uses of 'father' in legal contexts, as seen in the debate between Rabbi Eliezer and Rabbi Akiva over whether 'father' in certain passages refers to a biological parent or an idolatrous object of devotion Yevamot 48b:1. Jewish theology does not develop the title into a doctrine of divine persons, and it's never applied to a human religious leader as a formal ecclesiastical rank in the way Christianity does with priests or abbots.

In Christianity, 'Father' carries enormous theological weight — it's arguably the most defining title for God in the New Testament. Jesus consistently addresses God as 'Father' (Abba), and the Lord's Prayer opens with 'Our Father.' Theologically, the title operates on at least three levels: (1) God as Father of all creation; (2) God as the eternal Father of the Son within the Trinity — the First Person in relation to the Second; and (3) God as adoptive Father of believers through faith and baptism. Scholars like Thomas Aquinas in the 13th century and more recently Wolfhart Pannenberg (d. 2014) have explored how divine fatherhood is both analogical and uniquely literal in Christian thought. The title also carries ecclesiastical meaning — priests and abbots are called 'Father' in Catholic, Orthodox, and some Anglican traditions, drawing on Paul's language in 1 Corinthians 4:15 about being a 'father' to his spiritual children. This layered usage — divine, trinitarian, adoptive, and ministerial — makes 'Father' one of Christianity's most theologically dense titles. It's worth noting that feminist theologians like Elizabeth Johnson (b. 1941) have challenged the exclusive use of masculine Father language, arguing it can distort the understanding of God's nature.

The Hebrew background is important: the Old Testament already used 'Father' for God Isaiah 63:16, and Genesis even uses it metaphorically for human authority figures Genesis 45:8, which shows the title had a rich semantic range before the New Testament deepened it christologically.

In Islam, 'Father' (ab in Arabic) is strictly a human title referring to biological or legal paternity. Applying it to Allah is not done — Islamic theology emphasizes God's absolute transcendence (tanzih), and the Quran explicitly rejects any notion that Allah begets or is begotten (Quran 112:3). The Quran instructs Muslims to call adopted children by their biological fathers' names, underscoring that fatherhood in Islam is a matter of lineage and legal identity, not spiritual metaphor: Quran 33:5 This verse was revealed in the context of the Prophet Muhammad's adoption of Zayd ibn Haritha, and it firmly grounds 'father' in biological reality rather than spiritual relationship.

The hadith literature also shows that 'father' questions were taken seriously in a literal, genealogical sense. In Sahih al-Bukhari, a man asks the Prophet directly, 'Who is my father?' and receives a specific human name in answer Sahih al Bukhari 7295. Similarly in Sahih Muslim, the Prophet identifies men's biological fathers by name when asked Sahih Muslim 6125. These accounts confirm that in Islamic practice, fatherhood is about traceable human descent — not a metaphor for divine relationship. The title 'Father' is therefore never used as a name or attribute of Allah in Islamic theology, worship, or the 99 Names (Asma al-Husna).

In the Tanakh, Israel directly addresses God as “our Father,” linking the title to God’s identity as Redeemer: “Surely You are our Father… You, O ETERNAL One, are our Father; From of old, Your name is ‘Our Redeemer.’” Isaiah 63:16 Beyond theology, “father” also functions as an honorific for high office; Joseph says God “has made me a father to Pharaoh,” meaning a chief adviser. Genesis 45:8 Rabbinic literature registers debate about how to read “father” language: Rabbi Eliezer takes “her father… her mother” literally, while Rabbi Akiva reads it polemically against idolatry, citing “They say to a tree: You are my father.” Yevamot 48b:1

Within the Christian Bible’s Old Testament, the people address God as “our Father,” explicitly tying the title to God’s redeeming action: “thou, O LORD, art our father, our redeemer; thy name is from everlasting.” Isaiah 63:16 Biblical usage also shows “father” as an honorific of authority—Joseph is called “a father to Pharaoh,” indicating a role akin to chief counselor. Genesis 45:8 On the basis of these texts, Christians read “Father” as a biblical divine title and also recognize its courtly, non-theological sense in ancient usage. Isaiah 63:16Genesis 45:8

In the Qur’an, the term “father” is emphasized in matters of lineage and legal naming: “Call them by [the names of] their fathers; it is more just in the sight of Allah.” Quran 33:5 Prophetic reports also record people asking the Prophet, “Who is my father?”, reflecting concern for accurate paternal attribution, and the Prophet answered by identifying the questioners’ fathers. Sahih al Bukhari 7295Sahih Muslim 6125 In the sources cited here, “father” functions as a human relational and legal term; these passages do not present “Father” as a divine title.
