The Principle
The modern prison system, with its requirements of humane treatment, rehabilitation programming, and freedom from degrading punishment, was built partly by religious reformers who argued from Scripture that the treatment of prisoners reveals the character of a society before God. John Howard and Elizabeth Fry - the two greatest figures in the history of prison reform - were both explicitly motivated by Matthew 25:36's 'I was in prison and you came to me,' and their campaigns directly shaped the legal principles that govern imprisonment today.
Biblical Foundation
Matthew 25:31-46 provides the foundational text. In Jesus's description of the last judgment, the criterion for separating sheep from goats is not formal religious observance but care for the vulnerable: 'I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me, I was naked and you clothed me, I was sick and you visited me, I was in prison and you came to me.' The identification of Christ with the imprisoned person - 'whatever you did for one of the least of these brothers and sisters of mine, you did for me' (25:40) - gave visiting and advocating for prisoners a directly theological significance: it was a form of ministry to Christ himself.
Hebrews 13:3 reinforces the obligation: 'Continue to remember those in prison as if you were together with them in prison, and those who are mistreated as if you yourselves were suffering.' The empathetic identification - 'as if you were with them' - requires not merely formal visiting but genuine solidarity with the experience of imprisonment.
Isaiah 61:1-3, cited by Jesus in his inaugural sermon at Nazareth (Luke 4:18-19), includes 'freedom for the captives and release from darkness for the prisoners' as part of the messianic agenda - a liberationist text that prison reform advocates have consistently invoked as biblical authorization for their work.
Historical Transmission
The early church took Matthew 25 literally: visiting and supporting imprisoned Christians was a recognized ministry, and the Didache (c. 100 AD) and Justin Martyr's Apology both describe Christians supporting imprisoned members financially. As Christianity became the religion of the empire, concern for prisoners shifted from a minority community's solidarity practice to a general charitable obligation of the now-dominant church.
Medieval canon law regulated prison conditions in ecclesiastical prisons and the church maintained some supervisory authority over secular prisons. Religious orders - particularly the Franciscans - maintained prison ministry as a recognized vocation. But systematic reform of prison conditions did not occur until the 18th century, when evangelical revival combined with Enlightenment human rights thinking to produce the reform movement.
John Howard (1726-1790) began visiting prisons in 1773 as sheriff of Bedfordshire and was so appalled by the conditions he found - unpaid jailers extorting money from prisoners, sick and healthy prisoners crowded together without sanitation, debtors and criminals mixed indiscriminately - that he conducted a systematic survey of British and European prisons over the following years. The State of the Prisons in England and Wales (1777) documented conditions in unprecedented detail and proposed specific reforms, citing Matthew 25 and the principle that those made in God's image deserve dignified treatment even when justly imprisoned.
Elizabeth Fry (1780-1845) visited Newgate Prison in 1813 and found women and children in conditions she described as worse than animals. She established Bible reading classes, a school for children in the prison, and organized the Association for the Improvement of Female Prisoners in Newgate (1817). Her testimony before Parliament, citing Matthew 25 and the Quaker principle that the inward light of God is present in every person, directly influenced the Gaols Act of 1823, which mandated basic standards of prisoner welfare and separated different categories of prisoners.
Key Champions
Howard and Fry remain the defining champions. Howard's international reputation - he died in Russia inspecting prisons there - and Fry's parliamentary testimony made prison reform a mainstream political cause with explicit biblical foundations. The Howard League for Penal Reform (founded 1866) and the Prison Phoenix Trust continue their work today.
In the 20th century, Charles Colson - Nixon's special counsel, convicted and imprisoned for Watergate-related offenses - converted to Christianity in prison and founded Prison Fellowship (1976), the world's largest outreach to prisoners, their families, and crime victims, explicitly based on Matthew 25. Colson's Angel Tree program, which provides Christmas gifts to prisoners' children, and his advocacy for restorative justice drew directly on the same biblical texts that motivated Howard and Fry.
Modern Application
The Eighth Amendment's prohibition on cruel and unusual punishment - the constitutional expression of the biblical principle that punishment must not degrade offenders beyond what justice requires - has been the basis for landmark prisoner rights decisions, including Estelle v. Gamble (1976, establishing the right to medical care), Hudson v. McMillian (1992, prohibiting gratuitous use of force), and Farmer v. Brennan (1994, requiring protection from prisoner-on-prisoner violence).
The Prison Rape Elimination Act (2003), which mandated federal standards for preventing and responding to sexual assault in prisons, was championed by a coalition that included Prison Fellowship and other evangelical organizations, demonstrating the continuing relevance of the biblical prison ministry tradition to contemporary criminal justice policy.
Scholarly Debate
The deepest scholarly debate concerns the purpose of imprisonment itself. Retributivists argue that prison is deserved punishment for wrongdoing and that rehabilitation programming may actually distort the appropriate punitive character of incarceration. Rehabilitationists argue that the biblical concern for the prisoner - Jesus's identification with the imprisoned person - demands treatment aimed at restoration, not merely suffering. Restorative justice advocates, drawing more directly on the biblical tradition, argue that the entire framework of imprisonment as the paradigmatic criminal sanction may be biblically questionable - that the Old Testament's preference for restitution over incarceration suggests a different approach to wrongdoing altogether. The Prison Fellowship's evidence-based rehabilitation programs, operating in hundreds of prisons across the United States, represent the most sustained institutional expression of the Matthew 25 prison ministry mandate in contemporary American law. Their InnerChange Freedom Initiative, subjected to independent academic evaluation, showed significant reductions in recidivism for program completers -- providing empirical support for the biblical conviction that human beings are capable of genuine transformation and that the prison system should be organized to facilitate it rather than merely to contain and punish. This combination of theological mandate and empirical evidence for rehabilitation over pure punishment reflects the biblical justice tradition's practical as well as moral contribution to criminal justice reform.
