Abraham

Abraham is the point at which Judaism, Christianity and Islam meet, and there is no evidence for him outside their scriptures.

The Genesis narrative gives him a migration from Ur of the Chaldeans through Haran to Canaan, a covenant sealed by circumcision, a promise of descendants as numerous as the stars, the birth of Ishmael to Hagar and Isaac to Sarah, and the near-sacrifice of a son. He is placed by the internal chronology of the Hebrew Bible in roughly the early second millennium BCE.

No inscription, archive or archaeological layer names him. This is not surprising for a pastoralist rather than a king, but it means the case rests entirely on whether the narrative preserves early memory. Mid twentieth-century archaeologists, led by William F. Albright, argued that the customs described, adoption practices, treaty forms, personal names, fit a second-millennium background and vindicated the patriarchal narratives. That case was dismantled from the 1970s by Thomas L. Thompson and John Van Seters, who showed the parallels fitted the first millennium at least as well, and pointed to anachronisms in the text: domesticated camels used as pack animals, Philistines in Gerar, and Ur described as Chaldean, a designation that belongs to the first millennium.

The current spread of scholarly opinion runs from a substantially later composition of the narratives in the exilic or post-exilic period, with no recoverable historical figure behind them, to the view that older traditions were reworked. Almost no one now defends the Albright synthesis. Nothing in this settles what the figure means to the traditions that trace themselves to him.

The near-sacrifice is the episode all three traditions dwell on, and they do not agree on who was nearly killed.

Genesis 22 names Isaac, and does so explicitly and repeatedly. In Jewish tradition the episode is the Akedah, the binding, and it is read at Rosh Hashanah; rabbinic commentary is preoccupied with the silences in the text, Abraham's, Isaac's, and the fact that Sarah dies at the start of the next chapter. The story is not read as a simple test passed but as something the tradition keeps returning to with unease.

The Quran narrates the sacrifice at 37:99-113 without naming the son. The identification with Ishmael became the dominant Muslim position but was not unanimous in early Islam: classical exegetes including al-Tabari record both identifications and weigh them, and some early authorities held for Isaac. The Ishmael reading became standard later. Eid al-Adha commemorates the event, and the Hajj rites are understood as retracing Abraham's, Hagar's and Ishmael's steps at Mecca.

The Christian reading takes Isaac as a type of Christ, a beloved son carrying the wood of his own sacrifice up a hill, and Paul makes Abraham the model of justification by faith rather than by law, because he was reckoned righteous before circumcision was instituted. That argument is doing work in Paul's own dispute about Gentile converts.

Three traditions therefore hold him as founder while disagreeing about which son carried the promise, which is the disagreement the shared ancestry produces rather than resolves.

What binds the three traditions to Abraham is not a biography but a covenant, and each marks its claim on him with a title of its own.

In Genesis the covenant is the spine of the story: a promise of land and of descendants, sealed by circumcision as its sign, and reckoned to Abraham as righteousness because he believed it before any law was given. Judaism knows him as Avraham Avinu, Abraham our father, first of the patriarchs and, in later tradition, the first to recognise one God amid idolatry.

Christianity, following Paul, made that pre-legal faith the model of justification: Abraham was counted righteous by trust, not by works of the law, which let Paul argue that Gentiles who share his faith are his children without becoming Jews first. He is the father of all who believe.

Islam calls him Ibrahim and gives him two titles that state his standing: Khalil Allah, the friend of God, from the Quran's statement that God took Abraham as a friend, and hanif, one of pure, original monotheism who, the Quran insists, was neither Jew nor Christian but one who submitted to God, so that the primordial faith is traced through him. The profession of the millat Ibrahim, the creed of Abraham, makes him not a shared ancestor at the edge of the story but its pattern.

Three founders' faiths, then, hold the same man as the point where right worship begins, and locate the start of their own distinctiveness in what they say he was.

Two of the best-known stories about Abraham are not in Genesis at all, and tracing where they are found says a good deal about how traditions grow around a founder.

The first is the smashing of the idols. Genesis says nothing of Abraham's youth; the story in which the young man destroys the idols in his father Terah's shop, leaves the axe in the hand of the largest, and then mocks his father's protest that statues cannot act, comes from rabbinic midrash, Genesis Rabbah, filling the silence about how a man raised among idolaters came to one God. The Quran tells a version directly (Sura 21): Ibrahim breaks the idols, argues with his people, and is thrown into a fire that God commands to be cool and safe for him. Later tradition names the king who casts him in as Nimrod.

The second belongs to Islam alone. The Quran has Ibrahim and his son Ishmael raise the foundations of the Kaaba at Mecca, praying that God accept it, and Islamic tradition connects to the same family the well of Zamzam that saved Hagar and the infant Ishmael, and the maqam Ibrahim, the station of Abraham, near the shrine. The rites of the Hajj are understood as retracing the acts of Abraham, Hagar and Ishmael, which places Abraham not at the origin of a rival lineage but at the physical centre of Muslim worship.

The figure the three faiths share is thus elaborated quite differently in each, and the differences are not incidental but load-bearing.
