The Principle
Among the most sophisticated institutions in biblical law is the City of Refuge - a designated place of safe haven where a person who had caused accidental death could flee from the victim's kin-avenger, receive protection, stand trial, and if acquitted, remain in safety until the death of the High Priest. The institution combined three distinct legal functions that modern law handles separately: temporary protective custody, impartial adjudication, and a kind of statute of limitations achieved through the High Priest's death. The city was not a place where guilt was hidden but where it could be fairly determined - a juridical institution, not merely a sanctuary.
Biblical Foundation
Numbers 35:11-12 establishes the principle: "Then ye shall appoint you cities to be cities of refuge for you; that the slayer may flee thither, which killeth any person at unawares. And they shall be unto you cities for refuge from the avenger; that the manslayer die not, until he stand before the congregation in judgment."
Deuteronomy 19:4-6 spells out the intended beneficiary: "And this is the case of the slayer, which shall flee thither, that he may live: Whoso killeth his neighbour ignorantly, whom he hated not in time past; As when a man goeth into the wood with his neighbour to hew wood, and his hand fetcheth a stroke with the axe to cut down the tree, and the head slippeth from the helve, and lighteth upon his neighbour, that he die; he shall flee unto one of those cities, and live: Lest the avenger of the blood pursue the slayer, while his heart is hot, and overtake him, because the way is long, and slay him; whereas he was not worthy of death, inasmuch as he hated him not in time past."
Joshua 20:3 adds the procedural dimension: the refugee must state his case at the city gate, and the elders must provide shelter pending a full hearing. Six cities are named - three on each side of the Jordan - carefully distributed so that no point in the land was more than a day's journey from refuge.
The theological rationale in Numbers 35:33-34 is profound: bloodshed pollutes the land, and only the death of the one who shed blood - or the clear establishment of innocence - can purify it. This is not mere sentimentality; it is a legal theology of communal moral pollution that underlies the entire institution.
Historical Transmission
The Church's right of sanctuary - an institution that protected accused persons who fled to consecrated ground - is the direct descendant of the cities of refuge. Canon law codified the right by the 4th century: the Council of Orange (441 CE) and subsequent councils specified that churches could not be forcibly entered to seize a refugee. Gratian's Decretum (c. 1140) discussed sanctuary extensively, citing the cities of refuge as the scriptural basis.
Medieval English law recognized sanctuary in both ecclesiastical and royal forms; some towns, most famously Beverley and Hexham, held royal charters granting permanent sanctuary rights modeled explicitly on the biblical precedent. Edward I's statute of 1279 regulated sanctuary procedure in terms recognizable from Numbers 35 - duration, conditions of stay, and the role of the clergy as analogues to the Levitical priests.
The Reformation largely abolished ecclesiastical sanctuary in Protestant countries: Henry VIII restricted it in 1534, and James I abolished it in 1623. The secular residue was the concept of diplomatic asylum - the protection offered to political refugees by embassies - which carries the same logic of protected space pending adjudication.
Michael Walzer's Exodus and Revolution (1985) argued that the entire tradition of political exile and asylum in Western political thought is saturated with Exodus-Deuteronomy imagery; the cities of refuge are one specific legal crystallization of this broader typology.
Key Champions
Ambrose of Milan (340-397 CE) was the most prominent early champion of ecclesiastical sanctuary, personally sheltering refugees from imperial violence. His resistance to Theodosius drew on the principle that the church was a jurisdiction beyond imperial reach - a direct translation of the city of refuge's logic into Christian institutional form. In the modern period, the Sanctuary Movement of the 1980s in the United States - in which over 500 churches, synagogues, and other religious communities sheltered Central American refugees fleeing deportation - explicitly invoked the biblical cities of refuge and the tradition of ecclesiastical sanctuary.
Modern Application
The 1951 UN Convention Relating to the Status of Refugees and its 1967 Protocol codify the modern right of asylum: no state may return a refugee to a country where they face persecution (the non-refoulement principle). The convention's drafters were acutely conscious of the Holocaust and the failure to protect Jewish refugees in the 1930s; they were building a secular legal structure to accomplish what ecclesiastical and royal sanctuary had once provided.
In Sale v. Haitian Centers Council (1993), the Supreme Court upheld the interdiction at sea of Haitian refugees, sparking intense legal and theological debate. Religious groups cited the cities of refuge as the theological grounding for their opposition. Sanctuary city policies, under which local governments decline to assist federal immigration enforcement, have generated ongoing constitutional litigation, with the term "sanctuary" explicitly evoking the biblical and canonical tradition.
Scholarly Debate
Benjamin Uffenheimer and other biblical scholars have debated whether the cities of refuge represent an earlier blood-vengeance system being rationalized or a later priestly systematization. The question affects how "original" the institution is as a legal innovation versus a codification of existing practice. A.D. Doob's comparative work on asylum in ancient Near Eastern law shows that protection of refugees at temples was common across Mesopotamia and Egypt, suggesting the biblical institution may be systematizing a widespread cultural practice rather than inventing a new one.
Comparative Perspective
Ancient Greek cities recognized the right of hikesia - ritual supplication at altars - as creating an obligation of protection. Roman law recognized the principle in a limited form through inviolability of temples. In Islamic law, the concept of aman - safe conduct - provides temporary protection to foreign nationals entering Muslim territory. The Buddhist concept of the sangha (monastic community) as a protected space has functioned in some Southeast Asian contexts as a form of de facto sanctuary. The universality of the institution across cultures suggests it responds to a deep human intuition about the difference between guilty and innocent killing and the right to be heard before being condemned.
