Why Does God Allow Slavery? A Comparative Religious Analysis

The Hebrew Bible undeniably contains legislation governing slavery — both the ownership of Canaanite slaves in perpetuity and the more limited indentured servitude of fellow Israelites. The so-called 'Curse of Ham' passage in Genesis, for instance, records Noah declaring, 'Let Canaan be a slave to them' Genesis 9:26, a text that was tragically weaponized for centuries to justify race-based slavery, despite most rabbinic authorities rejecting that reading as a divine command rather than a narrative observation.

The more interesting story is how rabbinic Judaism progressively tightened the legal screws on slaveholding. The Mishnah tractate Eduyot, compiled around 200 CE, records a famous dispute between the schools of Beth Shammai and Beth Hillel over a person who was 'half a slave and half free.' Beth Hillel initially allowed an awkward arrangement of alternating labor, but Beth Shammai argued this was unjust because such a person could marry neither a slave woman nor a free woman — violating the foundational principle that 'the world was created in order for people to be fruitful and multiply.' The ruling concluded that the master must be compelled to grant full freedom Mishnah Eduyot 1:13. This is a remarkable moment: the rabbis used human dignity and the purpose of creation to override property rights.

The book of Ezra frames Israel's own experience of subjugation under Persian rule as a kind of ongoing national slavery, yet insists God remained present even in that bondage Ezra 9:9. This theological move — finding divine faithfulness within, not despite, conditions of unfreedom — became central to how later Jewish thinkers processed suffering. Scholars like David Brion Davis (in Slavery and Human Progress, 1984) have noted that rabbinic law, whatever its limitations, created more pathways to manumission than most ancient legal systems. The question 'why does God allow slavery?' was, for the rabbis, less a theodicy problem and more a practical legal challenge they kept chipping away at.

Christianity's relationship to slavery is one of the most painful chapters in Western religious history. The New Testament neither explicitly abolishes slavery nor endorses it as a divine institution, but passages like Ephesians 6:5 ('Slaves, obey your earthly masters') and Philemon were used for centuries by slaveholders to claim divine sanction. Abolitionists, meanwhile, pointed to Galatians 3:28 ('neither slave nor free... all one in Christ Jesus') as the theological heart of the gospel. The same Bible, the same God — radically different conclusions.

The Old Testament passages that Judaism also inherited — including the Curse of Canaan Genesis 9:26 — were frequently cited in pro-slavery Christian theology, particularly in the antebellum American South. Theologians like Thornton Stringfellow published Scriptural and Statistical Views in Favor of Slavery (1856) arguing God positively sanctioned the institution. On the other side, Frederick Douglass, William Wilberforce, and the Quaker tradition argued that the arc of scripture bends toward liberation.

Most contemporary Christian theologians, including figures like N.T. Wright and Walter Wink, argue that God's 'allowance' of slavery reflects divine accommodation to fallen human social structures — what theologians call Heilsgeschichte, or salvation history unfolding gradually. God meets humanity where it is, then moves it forward. This doesn't fully answer the theodicy question, and many Black liberation theologians, including James Cone in The Cross and the Lynching Tree (2011), have insisted that comfortable theological explanations cannot paper over the real suffering caused when Christians used scripture to enslave. It's a live and unresolved debate.

Islam emerged into a 7th-century Arabian world thoroughly saturated with slavery, and the Quran neither abolishes the institution outright nor endorses it as a divine ideal. What it does — and this is the key theological move — is regulate it heavily while repeatedly incentivizing emancipation. Quran 24:33 is one of the most direct passages on the subject, instructing masters to grant freedom documents (mukātaba) to slaves who request them, provided there is 'aught of good in them,' and to provide them financial assistance from God's wealth Quran 24:33. The passage also explicitly forbids forcing enslaved women into prostitution — a prohibition that implicitly acknowledges the abuse was happening.

Quran 3:79 uses the Arabic word rabbāniyyīn — 'faithful servants of the Lord' — to distinguish proper devotion to God from any human claim to own another person's ultimate allegiance Quran 3:79. The theological point is that true slavery belongs only to God ('ibādah), and Quran 22:10 reinforces that God is 'no oppressor of His slaves' Quran 22:10, using the term 'ibād (servants/slaves) in its spiritual sense.

Classical Islamic jurisprudence, particularly the Maliki and Hanafi schools, developed extensive rules limiting how slaves could be treated, and manumission was listed as an expiation (kaffarah) for numerous sins — structurally encouraging freedom. Scholar Jonathan Brown (in Slavery and Islam, 2019) argues this created a system that was meaningfully different from chattel slavery, though critics like Kecia Ali counter that the legal protections were often aspirational rather than enforced. The question of why God didn't simply prohibit slavery outright is answered by many Muslim scholars through the lens of gradual reform — the same logic applied to the prohibition of alcohol, which came in stages.

Hebrew Scripture includes narratives and laws where the term “slave” (eved) appears in historical and legal contexts, including national bondage metaphors such as, “For slaves we are… yet our God has not forsaken us,” highlighting dependence on imperial powers and God’s sustaining mercy Ezra 9:9.

Another difficult text, “Let Canaan be a slave to them,” reflects ancient curse-traditions later misused, but as a verse it shows the Bible’s plain record of servitude language within primeval narratives Genesis 9:26.

Post-biblical halakhah sought humane outcomes: the Mishnah resolves that a person who is “half-slave and half-free” must be fully freed so he can fulfill marriage and procreation, compelling the master to manumit and accept a bond, prioritizing social order and dignity Mishnah Eduyot 1:13.

So, why does God allow slavery in these sources? The texts present regulation and mitigation within existing realities, alongside legal mechanisms that press toward freer, more ordered communal life Mishnah Eduyot 1:13Ezra 9:9.

Christian readings include the Hebrew Bible’s witness, where “slave” can denote political subjugation and dependence, as in, “For slaves we are, though even in our bondage God has not forsaken us,” a line Christians also encounter in their Old Testament Ezra 9:9.

Texts like “Let Canaan be a slave to them” show that Scripture preserves ancient social realities and curse traditions without offering them as timeless moral ideals; historically, such lines were cited, but the verse itself simply states the narrative curse Genesis 9:26.

Many Christian interpreters therefore frame the question as: God tolerates and regulates broken institutions in the biblical world while calling communities toward mercy and liberation themes recognizable already in Israel’s own testimony about bondage and God’s sustaining aid Ezra 9:9.

There’s active debate over how far regulatory texts imply divine endorsement; here I’m sticking to what the cited passages themselves say and not attributing later doctrinal positions without sources Ezra 9:9.

The Qur’an reframes the question by centering God alone as the object of servitude in worship: prophets don’t tell people, “Be slaves of me instead of Allah,” but to become devoted servants of the Lord through Scripture and teaching Quran 3:79.

Practically, the Qur’an mandates tools toward emancipation: if slaves seek a written contract of manumission, believers should grant it upon recognizing good in them and even share wealth to assist their freedom; it strictly forbids forcing slave-women into sexual exploitation, and promises divine mercy to the coerced Quran 24:33.

It also insists that ultimate accountability rests with God, “and Allah is no oppressor of His slaves,” signaling justice in the divine measure even amid human hierarchies Quran 22:10.

In sum, the Qur’an regulates existing structures, curbs abuse, opens avenues to freedom, and orients loyalty away from human masters toward God’s sole lordship Quran 24:33Quran 3:79.
