Mother-Teresa
Short answer: Mother Teresa (1910-1997) spent most of her life serving the dying and destitute in Calcutta with the Missionaries of Charity, and many Christians read Matthew 25:31-46 as the charter of that work. The passage describes the Son of Man seated on his throne of glory, separating people as a shepherd separates sheep from goats, and identifying himself with the hungry, thirsty, naked, sick, and imprisoned. Faithful Christians agree that Jesus commands mercy to the needy. They differ on whether the passage teaches that caring for the poor earns eternal life. It does not. Read in context, Matthew 25 is about the King's return and the evidence of a life that belongs to him, not a ledger of deeds that purchases salvation. Her service is worth examining in that light, neither dismissed nor mythologised.
Who Mother Teresa was and what she actually did
Anjezë Gonxhe Bojaxhiu was born in Skopje in 1910 to an Albanian family, joined the Sisters of Loreto, and taught school in Calcutta for nearly two decades before what she described as a call to serve the poorest of the poor. In 1950 she founded the Missionaries of Charity, a religious order whose sisters took vows of poverty, chastity, obedience, and a fourth vow of wholehearted free service to the poorest of the poor. The order grew from a handful of women to hundreds of houses across the world.
The work itself was unglamorous. Sisters picked dying people off railway platforms and street corners and brought them to homes where they were washed, fed, and allowed to die with some dignity. They ran homes for orphans, lepers, and the mentally ill. Mother Teresa became internationally famous after a 1969 documentary, and she received the Nobel Peace Prize in 1979. She refused much of the ceremonial wealth offered to her and kept living in the same simple conditions as her sisters.
She also became a lightning rod. Critics argued that her houses offered inadequate medical care, that she accepted donations from corrupt figures, and that her public stance against abortion and divorce made her a political symbol. Defenders pointed out that she was running hospices, not hospitals, and that her sisters were not trained physicians. These disputes are real and should not be airbrushed. What is not seriously disputed is the volume of her service and the fact that she did it among people most of Calcutta had abandoned.
Why Matthew 25 is the text people attach to her
Matthew 25:31-46 is the last major discourse in Matthew's Gospel before the passion narrative. Jesus describes the Son of Man coming in glory with all the holy angels, sitting on a throne, and gathering all the nations before him. He separates them into two groups. To one group the King says they fed him, clothed him, visited him. To the other he says they did not. Both groups ask when they saw him in such need, and the King answers that whatever was done to the least of his brothers was done to him.
Mother Teresa quoted this passage constantly. It gave her order its logic: Christ is genuinely present in the distressing disguise of the destitute, so serving a dying man on a slab is not charity from a distance but an encounter with the Lord himself. That reading is not sentimental. It takes seriously the identification Jesus makes between himself and the needy, and it explains why her sisters treated each dying person with ceremonial care rather than mere efficiency.
But the passage is doing more than issuing a command to be kind. It is a scene of final judgment. The King is not merely a model of compassion; he is the judge who decides destinies. Any use of this text, hers or ours, has to reckon with that frame rather than excerpt the kindness and discard the throne.
What Jesus actually says in Matthew 25:31-46
The scene opens with the Son of Man coming in glory, with all the holy angels with him, seated on the throne of his glory, as Matthew 25:31 states. All the nations are gathered, and he separates them as a shepherd separates sheep from goats, placing the sheep at his right hand and the goats at his left. The criterion he announces is concrete: the hungry were fed, the thirsty given drink, the stranger welcomed, the naked clothed, the sick and imprisoned visited.
What is striking is that neither group recognises him. Both ask the same question. The righteous did not know they were serving Christ; the unrighteous did not know they were neglecting him. Jesus answers with the identification that has driven Christian mercy for two thousand years: whatever was done to the least of these his brothers was done to him. The scene ends with the righteous entering eternal life and the others departing.
Notice the grammar of the passage. The King does not say the righteous earned their place by their deeds. He says they inherit the kingdom prepared for them from the foundation of the world, an inheritance, not a wage. The deeds are the evidence that they belonged to him, not the price of admission. That distinction is the hinge on which the whole interpretation turns.
The hard question: does Matthew 25 teach salvation by works?
Read in isolation, the passage can sound like a works-righteousness text: do these things and inherit eternal life. But Matthew has already told us how people enter the kingdom. In the Sermon on the Mount, Jesus pronounces blessing on the poor in spirit and the merciful, and he calls his disciples the light of the world, a city on a hill that cannot be hidden. Light is not the price of the city's existence; it is what a city on a hill inevitably is.
Paul is emphatic that no one is justified by works of the law. James is equally emphatic that a faith without works cannot save, and James 2:14 asks, what good is it, my brothers, if a man says he has faith, but has no works? Can faith save him? The two are not at war. Paul is describing the root, James the fruit. Matthew 25 belongs with James. It depicts the fruit that will be visible when the King comes, not the root that produces it.
So the honest answer is that Matthew 25 does not teach that mercy purchases salvation, but it does teach that a salvation which produces no mercy is not the salvation Jesus describes. The two errors are the same error from opposite sides: treating mercy as a transaction rather than as the natural fruit of belonging to the merciful King.
Mother Teresa, assurance, and the dark night she described
After her death, letters published with the encouragement of her order revealed that Mother Teresa had endured decades of spiritual darkness, an experience of the absence of God that she described in stark terms. Some readers took this as evidence of hypocrisy; others, including many Catholic writers, took it as evidence of a costly fidelity, of continuing to serve a God she could not feel. This is not a point where Scripture itself settles the matter, and Christians read her interior life differently.
What the letters do not do is contradict her public teaching. She continued to insist that the work was Christ's and that the poor were his. Whether her darkness was depression, a purifying trial, or a crisis of faith is a question no one can answer from outside. What can be said is that she kept serving when the emotional reward was gone, which is exactly what Matthew 25 describes: service to a Christ who is not visibly present in the person served.
The pastoral lesson here is not to canonise her or to diagnose her. It is to admit that faithfulness often runs ahead of feeling. If Jesus is hidden in the least of these, then the servant who cannot see him and serves anyway is doing precisely what the passage commends.
What her life does not prove and what it does illustrate
Mother Teresa's life does not prove that her specific methods were the best possible, or that every criticism of her institutions was wrong, or that her theology was correct at every point. Christians who admire her work need not pretend she was infallible. What her life illustrates is a specific claim Jesus made: that the needy are not interruptions to the spiritual life but the place where it is tested. That claim stands or falls on whether Jesus rose from the dead, not on how impressive any one servant was.
Her life also illustrates the limits of biography. We have the public record, some letters, and the testimony of those who knew her. We do not have her heart. Judgment belongs to the King in the passage, not to us. Whatever verdict history reaches, the text she served is still standing, and it addresses every reader regardless of whether they admire her.
The practical point is modest and demanding at once. If Matthew 25 is true, then how a person treats the hungry, the stranger, the sick, and the prisoner is not a side issue. It is one of the places where the reality of their faith becomes visible. That is not a reason to perform for an audience; it is a reason to look at one's own street, one's own city, one's own family.
How to read Matthew 25 without turning it into a slogan
First, read the whole chapter. The parable of the ten virgins and the parable of the talents come immediately before, and both are about readiness and faithful stewardship in the master's absence. Matthew 25 is a chapter about what faithful waiting looks like, and mercy to the needy is one form that waiting takes. Pulling verses 35-40 out and pasting them on a banner loses the setting.
Second, keep the identification in proportion. Jesus says the needy are his brothers in this scene, not that every needy person is automatically a Christian or that serving the poor replaces preaching the gospel. The New Testament holds both together: the apostles fed widows and preached Christ. There is no biblical warrant for choosing one and despising the other.
Third, let the passage search you rather than flatter you. It is easy to read it as a compliment if you already care about the poor, and equally easy to read it as a rebuke aimed at someone else. The two groups in the parable did not know which one they were in. That should produce humility, not self-congratulation, in every reader.
Biblical fidelity check
What Matthew 25:31-46 establishes is that the returning King will judge the nations, that he identifies himself with the hungry, thirsty, stranger, naked, sick, and imprisoned, and that mercy shown to them is reckoned as mercy shown to him. It does not establish that charitable deeds earn eternal life, that every act of relief is automatically an act of worship to Christ regardless of faith, or that the passage is a comprehensive doctrine of justification. The inheritance language rules out wages. What the text does is describe the visible fruit of a life that belongs to the King.
A common misreading is to treat the passage as teaching salvation by works, as if the sheep earned the kingdom by their charity. That reading contradicts the rest of the New Testament, including James 2, which is often enlisted on its side. James does not say works save apart from faith; he says a faith that produces no works is not the kind of faith that saves. The opposite misreading is equally wrong: treating mercy as optional, an extra for especially devout Christians. Neither error survives the text.
Other passages that speak to Matthew 25:31-46
Several related studies help place this passage in its biblical context. What Does 1 Corinthians 1:10 Mean? Context, Theology, and Application explores how a divided church is called to unity, which matters because mercy is a shared work, not a solo performance. What Does 1 Corinthians 1:9 Mean? Context, Theology, and Application looks at God's faithfulness as the ground of the believer's calling, the same calling that produces fruit in Matthew 25. 1 Corinthians 1: Called, United, and Boasting in the Lord traces the themes of the opening chapter, and 1 Corinthians 10: Warnings and Freedom considers how privilege without obedience ends in judgment, a warning that runs parallel to the goats in Matthew 25.
Frequently asked questions
Was Mother Teresa a Protestant or a Catholic?
She was a Catholic nun, born into a Catholic Albanian family, trained in the Sisters of Loreto, and founder of the Missionaries of Charity, a Catholic religious order. Her theology and practice were shaped by Catholic devotion, the mass, and the sacraments. Protestants and Catholics alike have admired her service, and many evangelicals have quoted her sayings in sermons. That shared admiration does not erase real differences between Catholic and Protestant understandings of salvation, which is why this study leans on the biblical text rather than on her example as a doctrinal authority.
Does Matthew 25 mean I have to sell everything and move to a slum?
No. The passage commands mercy to the hungry, thirsty, stranger, naked, sick, and imprisoned, but it does not prescribe one form that mercy must take. Some are called to radical relocation, as Mother Teresa was. Most are called to faithful generosity, hospitality, and presence in the ordinary places where they already live. What the text forbids is comfortable indifference. It does not require a specific address. Scripture speaks elsewhere of providing for one's own household, so the call is not to abandon responsibilities but to stop ignoring the needy within reach.
How do I respond if I have not cared for the poor as I should?
You repent and begin. The goats in the parable were surprised by their neglect, not defiant about it, which suggests that indifference often runs unnoticed until the King names it. The right response is not despair and not a frantic attempt to earn favour, but honest confession and a concrete change, beginning with the needy person nearest to you. James 2:14 asks what good a faith without works is, and the answer is that such faith cannot save, not because works save, but because they are the evidence of the faith that does.
