  • Recovering the Christian Tradition of Hospitality

    In a world marked by suffering, exclusion, and isolation, the Christian act of welcome and hospitality embodies the heart of God’s redemptive mission. To welcome another—especially the vulnerable—is both a witness to and participation in God’s reconciling work through Jesus Christ, who reveals a God that invites all humanity into divine fellowship. Hospitality, once central to biblical faith from Abraham to Christ, reflects God as the gracious host who welcomes creation and calls his people to extend that same generosity to others. In contrast to the alienation fostered by modern technological life, true community arises through authentic human connection, listening, and acceptance. Thus, hospitality is not a mere social courtesy but a core expression of Christian identity and mission (Missio Dei)—a tangible way of joining God in bringing justice, healing, and hope to a world in need.

    Historically, hospitality was foundational to both social and religious life. In the ancient world, it meant offering food, shelter, and protection to strangers, who were often vulnerable travellers. In Israel’s tradition, hospitality was a divine command rooted in the people’s own identity as “strangers and sojourners.” Jesus himself depended on the hospitality of others while also offering it—welcoming outcasts, sinners, and the poor. He taught that welcoming strangers and feeding the hungry were acts of service to Christ himself. The early church viewed hospitality as a hallmark of Christian faith: it was required of leaders, practised across social divides, and considered a sign of genuine discipleship.

    Through the early centuries, hospitality took physical, social, and spiritual forms, centered on shared meals and mutual recognition of human dignity. Christian distinctiveness lay in extending welcome not only to peers but especially to the poor and marginalized. Church Fathers such as John Chrysostom and reformers like Luther and Calvin emphasized that in welcoming the needy, one welcomed God. Monastic traditions carried this ethic forward, making hospitality to strangers a key part of their vocation.

    Over time, however, institutional and cultural changes weakened personal hospitality. The rise of hospitals, hospices, and hostels professionalised care for the needy, shifting it from personal to institutional settings. The household itself became smaller and more private, while the church’s social role changed under state influence. By the eighteenth century, hospitality was seen as outdated—a quaint domestic virtue rather than a radical Christian practice.

    This loss has impoverished Christian life. Without hospitality, the church loses a vital link between theology and daily moral action. Recovering hospitality can reconnect Christian belief with pressing social issues such as homelessness, disability, migration, and alienation. Ancient and modern practitioners alike show that hospitality is both risky and transformative—a practice that shapes communities of compassion and inclusion.

    Modern intentional Christian communities—Catholic Worker houses, L’Arche, and Benedictine monasteries among others—offer living models of this recovery. They welcome diverse strangers, live simply, and integrate prayer with service. Their hospitality is “a sign of contradiction,” embodying hope, reconciliation, and the possibility of love in a fractured world. In these communities, hospitality is both demanding and rewarding; it nourishes hosts and guests alike and depends on spiritual grounding and communal discipline.

    Hospitality is not limited to those living in intentional communities. It can and should be practised in ordinary homes and churches. Welcoming strangers—those disconnected from family, work, or community—creates spaces of safety, respect, and mutual blessing. Genuine hospitality involves listening, sharing life, and making space for others in one’s personal and institutional settings. It is not merely an attitude but a physical and relational act that mirrors God’s own welcome.

    Recovering this practice requires honesty about the failures and distortions of past traditions, as well as attentiveness to present realities. Hospitality must be adapted thoughtfully to modern contexts—balancing openness with boundaries, generosity with wisdom. It is both a spiritual discipline and a moral art, learned by practice, guided by mentors, and sustained by prayer.

    Ultimately, hospitality is presented as a theological lens and a way of life through which Christians can better understand and embody the gospel. It challenges self-protection and individualism, reorients believers toward the stranger, and manifests the Kingdom of God as a community of welcome. The author concludes that to recover hospitality is not to revive a quaint custom, but to reclaim a transformative Christian practice capable of addressing the deepest social and spiritual fractures of contemporary life.


    A definition of Christian Hospitality…

    Christian hospitality can be defined as the intentional and self-giving practice of welcoming others—especially strangers, the marginalised, and those in need—as an expression of God’s own gracious welcome revealed in Jesus Christ. Rooted in both the Old and New Testaments, it reflects God’s redemptive love, inviting all people into relationship and community. Christian hospitality is more than social kindness; it is participation in the mission of God (Missio Dei), embodying the gospel through acts of justice, compassion, and inclusion. It mirrors the divine example of Christ, who made space for all by offering himself in love, and calls believers to extend that same openness and care without expectation of reciprocation, thus making God’s reconciling presence visible in the world.

    Characteristics of Christian Hospitality…

    The key characteristics of Christian hospitality—as drawn from biblical theology and theological reflection—include the following:

    1. Welcoming the Stranger – At its heart, Christian hospitality extends love and welcome beyond family or friends to strangers, outsiders, and the marginalized, reflecting God’s inclusive love (Lev. 19:33–34; Luke 10:25–37).
    2. Imitating God’s Character – Hospitality mirrors God’s own nature as the divine host who welcomes humanity into relationship. It is an act of participating in God’s redemptive mission (Missio Dei) and embodying the gospel (Rom. 15:7).
    3. Self-Giving and Sacrificial Love – True hospitality requires making space for others, often at personal cost, as modeled by Christ who “emptied himself” (Phil. 2:7). It goes beyond convenience to costly compassion and selfless service.
    4. Inclusion and Justice – Christian hospitality breaks down social, cultural, and economic barriers, promoting justice, equality, and reconciliation. It prioritises the needs of the poor, widows, orphans, foreigners, and those excluded from community (Mal. 3:5; Matt. 25:35–40).
    5. Embodied Faith – Hospitality is not merely a feeling but an embodied, practical expression of faith—feeding the hungry, visiting the sick, welcoming the lonely, and offering shelter or companionship. It gives tangible form to the gospel.
    6. Reciprocity Without Expectation – True Christian hospitality expects no return; it is offered freely, mirroring God’s grace and generosity (Luke 14:12–14).
    7. Community and Fellowship – Hospitality restores and builds authentic human connection in a fragmented world, fostering mutual belonging and participation in the life of the church and God’s family.
    8. Eschatological Hope – Ultimately, Christian hospitality points toward the coming Kingdom of God—a foretaste of the eternal welcome at the “Marriage Supper of the Lamb” (Rev. 19:9), where all are gathered into God’s household.

    Together, these characteristics show that Christian hospitality is not merely a moral virtue but a theological practice—a way of living that reveals God’s love, justice, and welcome to the world.

  • The Hidden Environmental Toll of AI:

    How Data Centres Are Draining Power and Water

    As artificial intelligence continues its meteoric rise—powering everything from chatbots to autonomous systems—its physical footprint is often obscured behind slick interfaces and catchy headlines. Behind every “smart” response, there’s a sprawling data centre generating heat, consuming energy, and guzzling water. This reality raises urgent questions: at what cost does AI scale? And are we ignoring a growing environmental debt?

    Electricity Consumption: The Power Problem

    1. Explosive Growth in Energy Demand
      AI is driving an unprecedented surge in electricity consumption within data centres. According to the International Energy Agency (IEA), data centre electricity demand could nearly double, reaching ~945 TWh by 2030 under its base case. IEA Crucially, “accelerated servers” (i.e., those used for AI workloads) account for a disproportionate share of this growth, with electricity demand projected to rise by about 30% annually in some scenarios. IEA
    2. Grid Strain and Carbon Risk
      More power demand is not just a matter of flipping a switch. If that electricity comes from fossil-fuel-heavy grids, the carbon emissions multiply. Already, some studies have flagged that data centres’ carbon intensity (CO₂e per kWh) in the U.S. exceeds national averages by a significant margin. arXiv Without rigorous sustainable energy sourcing, scaling AI risks undermining climate goals — the very aspiration many proponents of AI claim to support.

    Water Consumption: The Underreported Crisis

    1. Cooling Isn’t Just Air
      Servers working on large AI models generate huge amounts of heat, and cooling them down is not trivial. Many data centres rely on evaporative cooling systems, which consume large volumes of water. The AI Journal+1 To put numbers on it: a 1 MW data centre can use up to 25.5 million litres of water per year just for cooling. World Economic Forum
    2. Indirect Water Use via Electricity
      The water footprint of AI isn’t limited to on-site cooling. The generation of electricity that powers these data centres also consumes water—especially in thermoelectric plants. ITU In fact, some analyses suggest that indirect water use (from power generation) may outstrip direct data-centre water use. ITU
    3. Escalating Global Risk
      According to Morgan Stanley, AI data centres’ water consumption could jump to ~1,068 billion litres annually by 2028 for cooling and electricity generation combined. mint+1 Many of these facilities are in regions already vulnerable to water stress. In the UK, for example, water resource constraints are projected to worsen, raising serious concerns about siting new “AI growth zones.” GOV.UK+1
    4. Life-Cycle Water Usage
      Beyond operations, AI’s water footprint also extends to the manufacturing of hardware: chip fabrication is notoriously water-intensive, requiring ultrapure water. The Economic Times+1 According to academic research, building and training large language models can consume millions of litres of water even before deployment. arXiv

    The Bigger Picture: Sustainability vs. Scalability

    • Transparency Gap: Despite the gravity of the issue, data centre operators and tech giants often underreport or obscure their resource use. The UK government’s own report highlighted how water and energy consumption data are “frequently overlooked or underreported,” complicating regulation and sustainability planning. GOV.UK
    • Local Pressure, Global Consequences: In water-stressed regions, placing massive AI data hubs could pit corporate infrastructure against local water needs—consumers, agriculture, ecosystems all potentially losing out. Global Action Plan+1
    • Technological Band-Aids Aren’t Enough: There is growing interest in circular water solutions—closed-loop cooling, water recycling, water replenishment—but adoption lags, and in many places, traditional open-loop systems still dominate. World Economic Forum
    • Regulatory Blindspots: There are increasing calls for mandatory environmental reporting from major tech players. Without such frameworks, we risk locking in unsustainable infrastructure. The Guardian

    Why This Matters — and What Can Be Done

    1. Strategic Policy Intervention
      Governments should require transparent reporting of energy and water metrics from data centres, especially those designed for AI. This data is essential for planning, especially in regions already under water stress.
    2. Smart Site Planning
      When selecting locations for AI data centres, planners must account for local water availability, water stress, and grid capacity—not just land cost or proximity to customers.
    3. Investment in Alternative Cooling
      Data centre operators should accelerate adoption of advanced cooling technologies (e.g., liquid immersion cooling, closed-loop systems) that greatly reduce water consumption.
    4. Green Energy Integration
      Pairing data centres with clean power (renewables, low-carbon generation) helps mitigate the carbon and indirect water costs tied to electricity production.
    5. Circular Water Economics
      Tech companies must invest in “water replenishment” projects (e.g., restoring water in stressed basins), wastewater reuse, and innovative water-management models as core parts of their growth strategy—not as peripheral CSR projects.

    Conclusion

    AI’s promise is undeniable: it has the capacity to transform industries, drive innovation, and unlock new capabilities in science, business, and society. But if we ignore its environmental footprint—especially in terms of energy and water—we risk fueling a technology boom that harms the very planet it purports to help.

    Scaling AI sustainably demands more than just faster chips and bigger models; it requires confronting the resource demands of the infrastructure that supports it—and making tough choices about power, water, and the long-term cost of “intelligence.” Without that reckoning, we may be building an AI future on foundations that are anything but green.

  • Remembering, Identity, and the “Us…Our” of Genesis 1:26

    Reflections Shaped by Rabbi Jonathan Sacks and Old Testament Scholarship


    Introduction

    I’ve recently been reading Rabbi Jonathan Sacks’ work on the Hebrew understanding of remembering (zakhar) and history. His reflections on how Jewish identity has survived thousands of years—often without land, king, or nation—have deeply influenced how I approached Genesis 1:26 this week.

    The phrase “Let us make humankind in our image…” becomes especially striking when we remember who Genesis was written for: a community of ex-slaves, refugees from Egypt, discovering a new identity under one God.


    Who Was Genesis Written For?

    Genesis addressed a particular people:

    • Families linked through shared lineage
    • Refugees liberated from Egyptian domination
    • A monotheistic community in a polytheistic world
    • A nation without land, king or political identity

    To these people, the plural “us…our” would have carried profound implications.


    Exploring the “Us…Our”: Insights from the Commentaries

    Hamilton’s Six Possibilities

    Hamilton outlines six potential explanations:

    1. A reference to surrounding polytheistic cultures
    2. A heavenly court
    3. God addressing creation itself
    4. The “royal we”
    5. God speaking to himself/themselves
    6. A proto-trinitarian conversation between God and the Spirit

    Hamilton does not commit to any one view, but importantly he argues that the author is not “too primitive” to conceive of unity-within-plurality.


    McKeown’s Contribution

    McKeown narrows the options to:

    • The royal “we”
    • A heavenly court
    • A proto-trinitarian reading

    He rejects any notion of polytheism and leans toward the proto-trinitarian option, supported by Cline’s argument that the Spirit functions as “another person within the divine being.”


    Walton’s Approach

    Walton places his focus not on “us…our” but on “image” and “likeness.”
    His deep engagement with Ancient Near Eastern culture is valuable, but on this particular question it sidesteps the nuances that Hamilton and McKeown explore.


    Which Interpretation Makes the Most Sense?

    As a 21st-century Christian, I naturally lean toward the proto-trinitarian interpretation. But beyond my bias, this interpretation speaks powerfully into Israel’s historical context.

    These refugees had just escaped a god-king, slavery, and the polytheistic worldview of Egypt. They were being offered a completely new identity:

    “You are not slaves.
    You are my representatives.
    You bear my image.
    You share in my work.”

    This gives them:

    • Identity – bearing God’s image
    • Authority – acting as God’s representatives
    • Purpose – taking part in ordering creation

    And without land of their own, they are given a vocation for the whole world.


    Wrestling With “Subdue” and “Rule”

    The terms subdue, dominion, and rule can feel uncomfortable. Today they often imply exploitation or excessive power—exactly what the Israelites had endured.

    A covenantal lens offers a different approach: leadership defined by service.
    Jesus’ words frame this beautifully:

    “Whoever wants to become great among you must be your servant.”
    —Matthew 20:26; Mark 10:43; Luke 22:26

    Israel’s calling was not domination, but stewardship.


    “In” the Image, Not “Of” the Image

    A key insight this week has been the difference between:

    Being created in the image

    and

    Being created of the image

    • “Of” implies possession or servitude—echoes of Pharaoh.
    • “In” implies relationship, participation, and shared purpose.

    This resonates with Jesus’ prayer in John 17:

    “May they be in us, just as I am in you…”

    Israel’s calling was deeply countercultural.
    Even Sabbath rest testified to this: in the ANE world only kings rested, yet Israel’s God gave rest to everyone—foreigners, servants, even animals.

    This was a revolution of identity.


    Memory, Identity, and “Zakhar”

    Goldingay brought me back to the Hebrew verb zakhar — to remember.

    Rabbi Sacks notes that Hebrew had no word for “history” until the 1800s; what Israel was commanded to do was remember—169 times in the Old Testament.

    “History asks, ‘What happened?’
    Memory asks, ‘Who am I?’”
    —Sacks

    Genesis 1:26 is not distant information.
    It is identity-forming memory.
    It is something that, in some sense, “happened to us.”

    No wonder the Psalmist marvels:

    “What are mortals that you are mindful of them?”

    This week’s study has been a genuine zakhar moment for me—
    a purposeful act of remembering that would not have happened by chance.


    Conclusion

    The plural “us…our” in Genesis 1:26 is more than a linguistic puzzle.
    It is part of a profound affirmation: humanity—every person—is created in God’s image, invited into God’s work, and given dignity not through land or power but through identity in God.

    For Israel, and for us, this passage is a call to remember who we really are.
