Weapons and Defense Stocks: A Christian Perspective

Introduction: A Question of Conscience for Christian Investors

Few investment decisions create as much moral tension for Christians as the question of whether to own shares in defense contractors. The issue combines financial analysis with theology, personal conviction with scriptural interpretation, and practical necessity with spiritual ideals. Is it possible to be a faithful Christian investor while holding stocks in companies that manufacture weapons? Or does such ownership compromise Christian values around peace, nonviolence, and stewardship?

This is not a new question. For nearly two thousand years, Christians have wrestled with how to live faithfully in a world that requires defense, security, and sometimes military force. Yet the modern investment landscape has made this tension sharply concrete. Millions of Christians, through retirement accounts, mutual funds, and direct stock ownership, own pieces of defense contractors without necessarily realizing it or having thought through the implications.

This article examines the question thoroughly, presenting biblical foundations, different Christian traditions’ approaches, the financial case for defense stocks, and practical frameworks for Christian investors to evaluate their convictions and portfolios. The goal is not to prescribe a single answer, but to equip Christians to make informed decisions aligned with their own prayerful discernment.

The Modern Defense Industry: Companies and Scale

The global defense and aerospace sector represents a substantial portion of the modern economy. The top defense contractors operate across multiple continents, serve dozens of governments, and employ hundreds of thousands of workers. Understanding the companies involved is essential for any investor considering this sector.

Major U.S. Defense Contractors

The “Big Four” of U.S. defense contractors dominate the landscape:

• Lockheed Martin Corporation generates roughly $60 billion in annual revenues, with about three-quarters coming from government contracts. The company manufactures fighter jets (F-35), missiles, space systems, and advanced electronics. It has a strong international presence and consistently ranks as the top defense contractor globally.
• RTX Corporation (formerly Raytheon Technologies) operates with annual revenues around $67 billion. RTX manufactures missiles, aerospace systems, and defense electronics. The 2020 merger of Raytheon Company and United Technologies combined two major defense players.
• Northrop Grumman Corporation generates approximately $36 billion annually, focusing on aerospace, defense systems, and technology services. The company builds military aircraft, missiles, and advanced defense technologies.
• General Dynamics Corporation produces around $40 billion in annual revenues from defense, aerospace, and information technology. The company manufactures military vehicles, submarines, and combat systems.

Beyond these four, companies like BAE Systems (UK-based, $33+ billion revenue) and numerous smaller defense contractors fill important niches in the industry ecosystem. Additionally, major technology companies including Microsoft, Google, Amazon, and Oracle have increasingly become defense contractors, securing significant government contracts. The convergence of commercial technology with military applications has blurred traditional industry lines.

Biblical Perspectives on War and Peace

Any Christian examination of defense stocks must begin with biblical foundations. Scripture presents complex, sometimes seemingly contradictory perspectives on military force, peace, and Christian participation in state defense systems.

Scripture on Peace and Nonviolence

Jesus’ teachings emphasize peace and nonviolence. In Matthew 5, He commands: “Blessed are the peacemakers, for they will be called children of God.” He instructs Peter to put away his sword (John 18:11), saying “all who draw the sword will die by the sword.” In the Sermon on the Mount, Jesus teaches believers to turn the other cheek, go the extra mile, and love enemies (Matthew 5:38-44).

The apostle Paul writes, “If it is possible, as far as it depends on you, live at peace with everyone” (Romans 12:18), and “Do not repay anyone evil for evil” (Romans 12:17). These passages reflect Jesus’ core teachings and set a high bar for Christian conduct emphasizing reconciliation, forgiveness, and nonviolence.

Old Testament law also reflects the value of peace. Isaiah’s eschatological vision declares, “He will judge between the nations and will settle disputes for many peoples. They will beat their swords into plowshares and their spears into pruning hooks. Nation will not take up sword against nation, nor will theyhere “nation will not take up sword against nation, nor will they train for war anymore” (Isaiah 2:4). This prophetic vision imagines a future where military force is unnecessary and absent—a sharp contrast with present reality.

These passages create a clear biblical ideal: peace and nonviolence are central Christian values, and participation in or profiting from warfare seems contrary to the spirit of Christ’s teaching.

Scripture on Legitimate Authority and Defense

Yet Scripture also acknowledges that civil government has legitimate responsibilities to maintain order and protect its people. Paul writes in Romans 13:3-4 that government rulers do not bear the sword in vain, but as “servants of God to bring punishment on the wrongdoer.” This passage acknowledges that legitimate government uses force to maintain order and justice.

The Old Testament includes numerous accounts where God commanded military action (Joshua’s conquest, David’s wars, etc.), and warriors like David and Joshua appear as heroes of faith in Hebrews 11. God permitted the existence of armies and military systems, and in some cases specifically authorized military campaigns.

This creates theological tension: How can Christians hold biblical ideals about peace while recognizing that governments must sometimes employ military force? Christian ethicists have long wrestled with this question, leading to different theological frameworks for faithful living.

Christian Traditions and Defense Stocks

Different Christian traditions have developed distinct approaches to war, military service, and questions about defending the state—differences that directly impact how Christians view defense stocks.or faithful living.

Just War Tradition

The Catholic, Orthodox, and mainstream Protestant traditions historically embraced “Just War” theory, developed by Augustine and refined by Thomas Aquinas. Just War theory provides criteria for when military force may be morally justified: legitimate authority, just cause, right intention, reasonable chance of success, last resort, and proportionality of response.

Under Just War theory, military defense of a nation against unjust aggression can be morally acceptable. Wars of defense against invasion, terrorism that threatens innocent lives, or other grave injustices might be permissible. Nations have a duty to protect their citizens, and military force may sometimes be necessary for that protection.

From a Just War perspective, some Christians see defense contractors as supporting this legitimate function of government. If a nation’s military defense is sometimes morally justified, then companies providing military equipment for that defense play a supporting role in a morally defensible enterprise. This view doesn’t romanticize war but recognizes that in a fallen world, military force sometimes serves justice and protection.

This framework creates space for Christian investment in defense stocks, though it doesn’t require such investment. A Christian holding Just War convictions might reasonably choose to invest in defense companies, or reasonably choose not to.

Anabaptist and Peace Church Traditions

In contrast, the Anabaptist tradition (Mennonite, Brethren, Quaker, and other “Peace Churches”) has historically rejected Christian participation in military force. This tradition emphasizes the radical demands of Jesus’ teaching about nonviolence and argues that Christians cannot participate in warfare. From this perspective, a Christian should refuse military service and certainly should not profit from military production.tate purposes, and that resolving conflict through military means reflects the world’s values rather than Christ’s kingdom. For these Christians, owning defense stocks is troubling—it represents profiting from an enterprise fundamentally at odds with Christian commitment to nonviolence.

This tradition takes seriously Jesus’ words and example, interpreting them as prohibiting Christian participation in violence, including through corporate ownership.

Modern Evangelical Perspectives

Modern evangelical Christianity is diverse on this question. Many evangelicals embrace Just War theory or modified versions of it, believing that defense of one’s nation can be compatible with Christian faith. From this perspective, defense stocks can be a legitimate investment choice, though not a mandatory one.

Other evangelicals, influenced by Anabaptist theology or by conviction that Jesus’ teaching on nonviolence is binding, take positions closer to Peace Church traditions. These evangelicals are uncomfortable with owning defense stocks.

Some evangelical leaders have become more pacifist in recent decades, influenced by deeper engagement with Jesus’ teaching and by recognition of how Christian nationalism sometimes distorts Gospel values. This has led more evangelicals to reconsider their stance on military investment.

How Major Christian Investment Funds Approach Defense Stocks

Christian mutual funds take different approaches to defense stocks, reflecting the theological diversity within Christianity. Understanding these approaches helps Christian investors discern their own convictions.estment Funds Approach Defense Stocks

Christian mutual funds take different approaches to defense stocks, reflecting the theological diversity within Christianity. Understanding these approaches helps Christian investors discern their own convictions.

Strict Exclusion

Some Christian funds, often aligned with Peace Church traditions or pacifist theology, exclude all defense contractors from their portfolios. These funds screen out companies that manufacture weapons or derive significant revenue from military contracts. Examples include funds managed with pacifist conviction or funds that serve Mennonite, Quaker, and Brethren communities.

This approach reflects the conviction that Christians should not profit from warfare in any form. It’s a clear, consistent position: if war and weapons are wrong, then owning companies that make them is also wrong.

Selective Exclusion

Many mainstream Christian funds take a middle approach: they exclude companies whose primary business is weapons manufacturing (especially controversial weapons like landmines or cluster munitions), but they permit investment in diversified defense contractors whose military business is one segment among many.

These funds might exclude Raytheon (now RTX) or Lockheed Martin if they believe defense revenue is too substantial, but they permit investment in companies like Boeing or larger technology firms where defense work exists but isn’t the primary business. The logic: a company that makes commercial aircraft, some of which are used militarily, is different from a company whose primary purpose is manufacturing weapons.flects a view that while some weapons raise serious ethical concerns, diversified companies serving multiple markets can be acceptable investments. This approach tries to balance theological concerns with practical investment reality.

These funds might ask: Is defense revenue 40% of the company, or 10%? Is the company primarily making weapons, or is defense one of several business segments? The percentage and prominence matter to their screening process.

No Specific Defense Screening

Some Christian funds don’t specifically screen for defense exposure at all. They focus their ethical screening on other criteria (environmental impact, labor practices, corporate governance, gambling, alcohol, tobacco, etc.) without addressing defense contractors specifically.

This approach acknowledges theological diversity: Christian investors have different views on military ethics, so the fund doesn’t presume to exclude defense stocks. Instead, they leave that decision to individual investors’ consciences.

These funds reflect confidence that faithful Christians can reasonably disagree on whether owning defense stocks is appropriate. Some Christian investors may hold defense stocks while maintaining deep Christian conviction and ethical commitment in other areas.

Why Defense Stocks Attract Investors

Beyond the moral and theological dimensions, defense stocks attract investors because they offer genuine financial appeal. Understanding this helps Christian investors make informed decisions.

Stable Revenue and Demand

Defense contractors serve government customers with multi-year contracts, creating predictable, recurring revenue. Governments worldwide have increased defense spending, and the major U.S. defense contractors have benefited from this trend.eapons when used indiscriminately. Christian funds typically exclude such weapons, but they disagree on whether to exclude all military production.

Defense companies also argue that their work serves legitimate national security purposes. They employ hundreds of thousands of workers, drive technological innovation (aerospace technology, advanced materials, computing systems often originate in military research), and contribute to government functions that most Americans support.

Diversification Argument

Defense contractors are often highly diversified. Let’s examine the major contractors more closely:

• RTX Corporation: Beyond military systems, RTX operates a large commercial aerospace business (making parts for commercial aircraft), and significant intelligence and defense services operations that serve civil government agencies. Military work is substantial but one customer segment among many.
• General Dynamics: Beyond combat systems and submarines, operates significant aerospace and information technology divisions serving commercial customers.
• Northrop Grumman: Operates innovation, technology, and services divisions across both military and civil sectors.
• Boeing: Commercial aircraft dominate their business, though they also have defense contracts.

From this perspective, these are technology and aerospace companies that happen to have military customers, rather than purely military contractors. Christian funds claiming selective exclusion often rely on this distinction—they argue they’re not funding “weapons manufacturers” but rather aerospace and technology companies that serve multiple customer bases.ence agencies. Again, military work is one customer segment among many, and these companies argue they shouldn’t be excluded from Christian portfolios simply because one customer happens to be the Department of Defense.

The counter-argument from strict exclusion advocates: These companies derive billions from military contracts. The sophistication and profit margins of military work drive corporate strategy. Claiming they’re “not really weapons companies” minimizes the reality of their military orientation.

A Framework for Christian Discernment

Given the complexity—legitimate theological disagreement, financial reality, and practical investment decisions—how should Christian investors approach this question?

Clarify Your Theological Foundation

Begin by examining what Scripture and Christian tradition say about war, military force, and Christian participation in state defense functions. Your theological conviction should be the starting point, not financial return.

Ask yourself:

• Can military force ever be morally justified? Under what circumstances?
• If yes, does that mean Christians can participate in, or profit from, military enterprises?
• What does Jesus’ teaching about nonviolence require of me as an investor?
• Which Christian tradition(s) speak most directly to my convictions?

This theological work is essential. If you haven’t thought through these questions, you’re likely letting cultural assumptions or financial considerations determine your investment choices rather than your prayerful Christian conviction.

Understand How Your Funds Are Invested

Many Christians unknowingly own defense stocks through broad-market index funds and mutual funds. If you have an IRA, 401(k), or other retirement account invested in a total market index fund, you almost certainly own defense exposure. Ask how the fund screens for it. Most investment firms will tell you their screening criteria. defense exposure, ask how the fund screens for it. Most investment firms will tell you their screening criteria.

If the fund says “We include some defense exposure” or “We exclude weapons manufacturers but not diversified defense companies,” you can then decide whether that aligns with your convictions. If you want zero defense exposure, you may need to look for specialized Christian funds with strict exclusions.

Transparency matters. Good fund managers will clearly explain their approach. Be wary of funds that are vague about their screening criteria or that claim ethical investing without specifying what that means.

Accept Tradeoffs

Few investment options are perfectly aligned with Christian values. Even ESG funds and Christian-specific funds involve imperfect compromises. Your options are not:

• Option A: Perfectly pure Christian investment with maximum returns
• Option B: Maximize returns and abandon values

Your real options are more like:

• Strict exclusion of defense (and potentially other industries): Lower overall market returns, very clear conscience
• Selective defense screening: Moderate compromise on conscience, better returns than strict exclusion
• No specific defense screening but other values-based criteria: More defense exposure but focus on other values
• Broad market index investing: Maximum financial returns, minimum control over investment choices

Each option involves choosing which values and compromises you’re willing to accept. There’s no “right” answer that works for everyone—but there is a right process: clear theology, honest assessment of your fund holdings, conscious choice about the tradeoffs you’ll accept.rnment.

The Difference Between Owning Stocks and Other Connections to Defense Industry

Finally, it’s worth reflecting on how owning defense stocks fits within the broader landscape of involvement with defense industry. This isn’t primarily a financial question but an ethical one.

Christians are deeply embedded in defense industry work. Millions work for defense contractors as engineers, managers, administrative staff, and hourly workers. Millions more work in defense-related government agencies. These folks provide for their families through defense work, and most aren’t engaged in anything they’d consider immoral—they might be designing efficient manufacturing systems, managing human resources, maintaining facility infrastructure, or handling logistics.

Christians also drive highways built partly with military funding, use internet technology that originated from military research (ARPANET), and live under government protection that depends on military capability. We participate in defense in countless indirect ways.

The question of owning defense stocks is, in this context, one decision among many ways that Christians inevitably interact with military systems in modern society.

This doesn’t mean the question is unimportant. It means that a Christian’s opposition to owning defense stocks shouldn’t come with judgment of Christians who work in defense industries, or dismissal of the legitimate security functions that military serves. We’re all implicated in military systems to some degree. The question is: what’s the right balance for you, given your convictions?

Screening Your Portfolio: Practical Steps

If you want to assess your current investments for defense exposure and make intentional choices, here are practical steps:es respect.

Screening Your Portfolio: Practical Steps

If you want to assess your current investments for defense exposure and make intentional choices, here are practical steps:

1. Identify Your Holdings

Gather statements from all investment accounts: IRAs, 401(k)s, brokerage accounts, mutual funds. Many people are surprised to discover they hold defense stocks through index funds or diversified mutual funds. Write down (or gather electronically) which stocks or funds you own and what percentage of your portfolio they represent.

2. Determine Fund Content

For mutual funds and index funds, look up the fund’s holdings online. Major funds provide lists of the companies they hold. Search the fund prospectus or fact sheet for information about their ethical screening or values-based approach.

If the fund doesn’t disclose its screening approach clearly, contact the fund company directly. Ask: “Does your fund include defense contractors? If so, which ones, and what percentage of the fund’s assets do they represent?” Legitimate fund managers should answer these questions clearly.

3. Research Specific Companies

If you own defense stocks directly, research what percentage of each company’s revenue comes from military contracts. Public companies disclose this in their SEC filings (the 10-K annual report). You can find these through the SEC website (sec.gov) or through the company’s investor relations website.

For example, a 10-K might show that 60% of RTX’s revenue is military-related, while 40% is from commercial aerospace. This helps you assess whether the company matches your values criteria.

4. Make Intentional Choices

Based on your theology and your assessment of your current holdings, decide whether you want to reduce defense exposure, keep it the same, or change your approach. You might: fund choices with some defense exposure, you may need to accept that compromise if you want broad diversification and reasonable returns.

– Switch to Christian-screened funds: Many Christian investment companies offer funds specifically screened for defense contractors. Some offer strict exclusion; others use selective screening. Choose a fund that matches your values.

– Switch to ESG funds: Environmental, Social, and Governance (ESG) funds often screen for defense exposure, though their criteria vary widely. Research the specific fund’s approach before investing.

– Diversify into alternative investments: Some investors use alternatives like bonds, dividend-paying stocks, or real estate investment trusts to reduce their exposure to large-cap stocks, which often include defense contractors.

– Accept intentional compromise: You might decide that you’re willing to own defense stocks if they’re a small percentage of your portfolio, or if they come with strong commercial business segments, or if the alternative would be to abandon investing entirely. That’s a valid choice if you’ve made it deliberately.

The key is making a deliberate choice aligned with your theology, not passively accepting whatever your fund manager chose.

5. Monitor and Update

Portfolio decisions aren’t permanent. Review your holdings annually or whenever your circumstances or convictions change. Fund compositions shift. Companies shift their business focus. Your theology may develop. What felt like an acceptable compromise five years ago might not feel acceptable now, or vice versa. Revisit the question periodically.

Conclusion: Conscience, Conviction, and Careful Discernment

The question of whether Christians should own defense stocks doesn’t have a single biblical answer that all faithful Christians will agree on. Scripture permits legitimate national defense while also calling Christians to prioritize peace and nonviolence. Christian traditions disagree thoughtfully on how to balance these tensions.on legitimately support multiple perspectives on military force, some Christians will conclude they should not own defense stocks. Others will conclude they can own them with clear conscience, especially if they’re part of diversified companies. Still others will accept selective defense exposure as a reasonable compromise given the realities of modern investing.

What matters is that you arrive at your decision deliberately, not passively. You should:

• Understand what Scripture and your Christian tradition teach about war and military force
• Know what you actually own and how much defense exposure you have
• Make conscious choices about your investments rather than delegating those choices entirely to fund managers
• Revisit your decisions as your theology develops and your circumstances change

Most importantly, apply the same careful Christian discernment to investment choices that you apply to other areas of life. Your money reflects your values and priorities. How you invest is a spiritual matter, not merely a financial one.

Whether you conclude that owning defense stocks is incompatible with Christian discipleship or that Christians can own them with clear conscience, the process of discernment—of praying, studying Scripture, examining your convictions, and making deliberate choices—honors God far more than unthinking acceptance of whatever your financial advisor recommends.

The goal of Christian investing is not maximum returns at the expense of integrity, nor is it impossible purity that abandons financial responsibility. The goal is faithful stewardship: using your resources in ways that reflect your deepest Christian commitments and convictions.
