Should Christians Screen Their Investment Portfolios?

The Lie of the Clean Portfolio

Scripture does not require Christians to screen their investment portfolios for “biblical value violations.” The instinct underneath the screening movement is honorable — Christians should think carefully about what they own — but the theological framework built around that instinct rests on claims the New Testament does not actually teach. The promise on offer is appealing: a portfolio cleansed of moral compromise, an investment account a serious Christian can sleep over. The promise cannot be kept on the terms it is offered. Not because Scripture is indifferent to what Christians do with their money, but because the cleanness on offer is not the cleanness the gospel actually provides.

A word on the title before the argument begins. The “lie” named in the subtitle is the promise embedded in the framework, not a charge against the sincerity of the people who advance it. Screening advocates are, in my experience, largely honest about what they think they offer. The argument here is that what they think they offer cannot, on Scripture’s terms, actually be delivered — and that the framework’s promise, however sincerely made, names a kind of cleanness the gospel itself does not locate where the framework wants it located.

What is at stake in this conversation is more than a technical question about asset selection. A multi-billion-dollar industry has built its marketing around the implicit claim that screened portfolios are the more faithful Christian choice — that holding a “clean” portfolio is part of what serious discipleship requires, and that the un-screened Christian investor stands at some distance from the obedience to which he is called. That claim is not a small one. It binds Christian consciences. It implies that ordinary participation in public markets carries a moral weight Scripture itself does not place there. And it sends Christians into a stewardship posture that, when the texts are taken on their own terms, the New Testament neither requires nor commends. The cost of getting this wrong is not financial. It is pastoral.

The people drawn to the screened approach are often the most morally serious investors I meet, and their argument deserves better than a strawman. So before pushing back, I want to set their case out at its strongest.

The Case For Screening, At Its Strongest

Begin where the screening advocate begins. If God owns everything, then no financial decision is morally neutral. The steward is accountable for what is done with the Owner’s resources — in giving, in spending, in earning, equally in investing. That premise is shared ground.

The second move follows. Owning shares of a company is not nothing. The shareholder receives dividends, votes proxies, profits when the company prospers and loses when it falters. To say “I am a part-owner of this company but bear no implication in what it does” sounds like the sort of distinction lawyers make to keep a conscience quiet. Surely partial ownership confers partial responsibility.

The third move makes the case biblical. The Scriptures contain a persistent pattern of separation from evil. Touch no unclean thing. Come out from among them. Have no fellowship with the unfruitful works of darkness. These are not marginal verses. They form a posture — and the screening advocate asks why investment should be exempt from a separation that governs everything else in the Christian life.

The fourth move is the hardest to dismiss, because most Christians already hold it elsewhere. Few of us would knowingly purchase a product built by trafficked labor. Few would shop at a store openly funding the destruction of unborn life. The principle that we do not materially associate with grave evil is one we apply across the moral landscape. Why not to the companies we own?

The fifth move closes the developed case. Screened funds do not only avoid evil — they direct capital toward companies whose work the Christian wants to support. The screen is not only a no. It is also a yes. A strategy that lets the steward say yes to faithful work with the same instrument he uses to say no to corrosive work is a real advance, not a symbolic gesture.

And then there is a sixth move, simpler than any of these, which is probably what most Christians who screen actually argue from. The five moves above are what a theologically trained advocate would offer. The sixth is what your neighbor across the pew is thinking. It runs like this: if you can reduce your holdings in companies whose practices you find morally objectionable, and the cost is low or none, why would you not? The default, on this view, is screening. The burden is on the non-screener to explain why he holds what he does not want to hold. That intuition is doing most of the actual persuasive work in the screening industry’s conversations with potential clients, and any honest engagement with the case has to take it on its own terms.

That is the argument at its strongest — six moves, each resting on a premise serious Christians already hold. The developed case is more substantive than the marketing language around it usually credits, and the populist version is more rhetorically powerful than its critics usually concede.

I have come to believe the case is wrong. Not because the moves are dishonest — they aren’t — but because each one, followed carefully, runs into a New Testament that gives a different answer than the screening framework expected.

Paul Sent the Corinthians Back to the Market

The most relevant passage in the New Testament for the screening question is the one the screening movement has largely failed to reckon with.

The setting matters. First-century Corinth was a port city wrapped up with pagan worship at depths no modern portfolio entanglement can match. Walk into the public market — the macellum — and a substantial share of the meat for sale had begun its journey on a temple altar. The sacrifice went up to the god. The priests took their portion. What was left moved out through ordinary commerce and ended up on dinner tables across the city. No one labeled the cuts that had passed through the rite, because there was no aisle for cuts that hadn’t. The temple and the marketplace ran on a single supply chain because, in important respects, they were a single supply chain.¹

The Corinthian believers wrote to Paul with a question that maps cleanly onto the one the screening movement asks: could a Christian participate in an economy this entangled, or did participation amount to complicity?

Paul’s answer is not the one the screening framework would predict. He gives them no list of approved vendors. He proposes no certification system. He sends them back to the same market they had been trying to escape, and grounds their freedom in something more comprehensive than any workaround: Eat whatever is sold in the meat market without raising any question on the ground of conscience (1 Cor. 10:25). The reason he gives is the one that ought to settle this for any Christian paying attention to the rest of the canon: for the earth is the Lord’s, and everything in it (10:26, quoting Psalm 24:1).

That is the load-bearing claim, and it reshapes the question. The Owner’s lordship extends over the whole created order, including its markets, including the tangled and morally compromised parts of those markets, including the very systems organized around things he hates. No corner of commercial life sits structurally outside his reach. The idol-system isn’t real enough to threaten the believer’s standing through a cut of meat. The temple economy didn’t carry the metaphysical weight the purity framework wants to give it. Neither does an index fund.

Paul does, however, name an exception, and the exception is decisive. The freedom he gives in the marketplace does not extend to the temple itself: reclining at the cultic meal, eating in the posture of participation in the rite, is something he categorically forbids (1 Cor. 10:14–22). That isn’t commerce. That’s allegiance. The Christian cannot offer allegiance at two altars at once, because worship is a declaration of loyalty and loyalty doesn’t split. Commerce in an entangled economy is not allegiance. It is the unavoidable condition of human life on this side of the new creation.²

Owning shares of a publicly traded company falls on the commerce side of Paul’s line, not the cultic side. It is participation in a tangled economy, not allegiance to the practices of every company in the fund. The theological move that grounds Christian freedom in the macellum grounds it in the brokerage account. The earth, then and now, is the Lord’s.

The Direction the New Testament Goes on Purity

The screening framework also runs against the whole trajectory of the New Testament on the question of clean and unclean.

The Mosaic law had given Israel a real system of ritual distinctions — covering what could be eaten, what could be touched, who could enter the holy spaces. It was a true system, given by God for purposes the Old Testament does not hide: marking out a people, schooling them in the seriousness of holiness, pointing forward to a cleansing the system itself could only prefigure. The system did real work, in its own time, under its own covenant.

The New Testament moves in one direction on what comes next. Jesus himself, in Mark 7, declares all foods clean by reinterpreting the source of defilement: not what enters the body from outside but what comes out of the heart (Mark 7:14–23). Peter’s vision in Acts 10 — the sheet lowered with the unclean animals, the divine voice instructing him to eat — is interpreted by Peter himself as the end of the old distinction: what God has made clean, do not call common (10:15). The Jerusalem Council in Acts 15 works out the practical implications for Gentile believers. Paul, writing to the Galatians, treats any move to slip the old code back in as a marker of covenant standing as nothing less than a betrayal of the gospel. Colossians puts it plainly: Let no one pass judgment on you in questions of food and drink, or with regard to a festival or a new moon or a Sabbath. These are a shadow of the things to come, but the substance belongs to Christ (Col. 2:16–17).³

To insist that a Christian portfolio must be scrubbed of certain holdings to be faithful — that the unscreened investor stands in some sense compromised before God — is to recreate, in the territory of finance, the very kind of code the New Testament has worked deliberately to fulfill and set aside. It is a category the gospel does not give us back.

The disagreement inside the screening industry itself is telling. Some firms emphasize one cluster of social-issue criteria. Others work from a broader human-flourishing framework. Catholic screens agree with evangelical ones on certain points and diverge sharply on others — contraception, capital punishment, and more. If the screens were exegetically derived, why would careful Christians produce screens that diverge so widely? The simpler explanation is the right one. The screens reflect the moral priorities of particular theological communities at a particular cultural moment. That can be a legitimate thing, but it is not “biblical investing” in any comprehensive sense.

What the Steward Actually Owes the Owner

There is also a financial reality the screening pitch tends to skip past, and it matters more than anything else for the moral analysis. When most people imagine “investing in a company,” they picture money flowing from their account into the company’s treasury. That picture is wrong for almost every share purchase you and I are ever going to make.

Companies receive money from issuing shares in only a few specific circumstances. The largest by far is the initial public offering — the moment a company first sells shares to the public. Sometimes there are follow-on issuances years later, where the company sells additional shares and collects new proceeds. These primary-issuance events are when companies actually make money from the stock market. Outside of those events, the shares trade hands among investors, and the company is not part of the transaction.

Two things about those primary-issuance events are worth knowing. They are rare in any given company’s life — most large public companies have one IPO and a handful of secondary offerings stretched across decades. And they are mostly closed to retail investors. Initial allocations go to large institutional investors, mutual funds, and investment banks’ preferred clients. By the time a typical Christian saving in a 401(k) ever sees the stock as available, the IPO is over and the company has already received its cash. The retail investor enters the picture in the secondary market, buying from another investor at the prevailing price. The company is not on the other side of the trade.

Take a recent example many Christian readers will remember. In the spring of 2023, a marketing decision by Anheuser-Busch — the parent company of Budweiser, Bud Light, and dozens of other brands — drew significant Christian backlash. Whatever one thinks of the controversy itself, the financial response is instructive. A substantial number of Christians who held shares of the company through their retirement accounts and brokerage holdings felt the instinct to divest as a moral statement. Many did. The share price fell during the period. To some observers, that fall looked like the company being punished for its decisions.

It was not, exactly. What actually hurt Anheuser-Busch was the consumer boycott — Americans declining to buy the company’s products in the months following the controversy. That action affected the company where companies actually make their money: at the cash register, where customers exchange dollars for products. The boycott showed up in declining sales, lost shipments, and market share handed to competitors. The share price decline followed the revenue decline, because the market revised its expectations of the company’s future earnings downward. The share price fell as a consequence of the boycott of the product. The divestment of the stock, considered separately, did not directly cost the company a dollar. When a Christian sold his shares in protest, the proceeds went to whoever bought those shares from him. Anheuser-Busch did not receive a refund. The company is funded by beer purchases, not by share trades.

This is the gap between what the screening pitch implies and how the markets actually work. The pitch implies that holding objectionable stocks funds the companies, and that screening them out withholds funding. Neither is true in the way the rhetoric assumes. Funding happens at issuance. Issuance happens rarely and is participated in mostly by institutions. Secondary trading does not fund. Divestment does not punish — though when it occurs alongside a consumer response that actually hits revenue, it can contribute to a price signal the company eventually notices.

There is one place where the funding logic does still bite, and it is worth naming honestly. If a company whose business is grave moral evil were to conduct an IPO, buying shares at that IPO would be direct funding of the enterprise. Christians should decline. If Planned Parenthood — to take the example most often raised in this conversation — were somehow to incorporate as a for-profit entity and offer shares to the public, no Christian could buy at the IPO without participating directly in funding the organization’s work. But that case almost never arises in practice. Planned Parenthood is a nonprofit and cannot offer shares. The kinds of enterprises Christians worry most about are typically either nonprofits (no shares to buy), private corporations (no public trading), or publicly traded companies whose IPOs are decades in the past (where the funding ship sailed long before any current Christian investor’s question came up).

This is where the stewardship framework outpaces the screening framework decisively. Consider what walking away actually accomplishes. The investor who exits a company on screening grounds is gone from that company entirely — no proxy, no engagement, no voice in any direction the company moves from there. The investor who keeps the position, casts the proxy with care, and uses the legitimate channels of shareholder engagement holds something. The first posture exits the room. The second stays in it. The first calls itself faithful stewardship. The second is what Scripture’s stewardship language actually describes.

The Parable of the Talents (Matt. 25:14–30) cuts straight across the assumption that the safer move is the faithful one. The servant condemned in that parable is not the one who took risk. It is the one who walked away, who buried what was entrusted to him, who chose the symbolic posture of safety over the active work of engagement. The master called that wickedness. He had asked for stewardship of what he owned. He got an investor unwilling to do the work ownership entailed. The parable does not map directly onto the screening question — its primary referent is the kingdom’s deployment of every resource into the Master’s purposes — but the underlying logic about how the Owner regards a posture of extraction is relevant. The servants commended in the parable engaged. The one condemned withdrew.

What ownership of a public position actually opens up, when held, is a set of legitimate channels of influence — the proxy vote, the shareholder resolution, formal and informal engagement with management, the ability to participate in collective action on governance questions. For the Christian holding individual stocks directly, those channels are exercised personally. For the much larger number who own through diversified mutual funds and ETFs, the channels operate at one remove: the fund manager votes the underlying proxies, sets the engagement policy, and represents the holdings to corporate management. That representation is not nothing. Fund managers’ proxy policies are public, are increasingly contested, and are responsive to investor pressure in the aggregate. When the Christian divests from broad-market funds into screened alternatives, he removes his capital — and any indirect voice he had in shaping the fund manager’s voting policy — from the companies he most wanted to influence. The screening firm, having declined to hold those companies, votes nothing of theirs. The conventional firm at least retains a vote, however delegated. Where ownership creates channels of influence, exit forfeits them. The screening posture trades the leverage of presence for the symbolism of distance. There may be cases where that trade is the right one to make. There are not as many as the marketing implies.

The “Why Not?” Question, Directly

The simplest version of the screening case is also the most common, and it deserves a direct answer. If you can reduce your holdings in companies whose practices you find morally objectionable, and the cost is low or none, why would you not? The burden, on this framing, sits with the non-screener: he has to explain why he holds what he doesn’t want to hold. That intuition deserves direct engagement, because in my experience it is the version of the case that does the actual persuasive work on most Christian investors. It is also the version that hides the most.

There are three assumptions inside the question, and each one deserves scrutiny.

The first is that the cost is genuinely low or zero. That assumption deserves more careful examination than it usually receives. A portfolio restricted on screening criteria is a portfolio whose investable universe has been deliberately narrowed. Whether the resulting opportunity cost is small or large depends on factors well beyond what I can address responsibly in a piece like this, and reasonable people in the industry disagree on the empirics. But the assumption that there is no cost — that screening is essentially free — is not a default that should be granted. There is, at minimum, the cost of giving up the engagement leverage that ownership of a position confers. There is, often, the cost of additional layers of fund-level expense passed on to the investor. And there is the cost of formation: a strategy that lets the steward feel clean without doing the harder work of engaged stewardship may be the more expensive choice spiritually, even where the dollar cost is small. Costs disguised as conscience are still costs.

The second assumption is that the default is extraction. The “why not screen?” framing assumes that screening is the natural starting point and that holding something requires affirmative justification. But that is not Scripture’s default. Paul’s default, in the most relevant passage in the New Testament, is active participation in an entangled economy grounded in the earth is the Lord’s. The burden of proof, on Scripture’s own framing, falls on the screener — to demonstrate that a particular kind of holding has crossed the line from ordinary commerce into cultic participation. Most cannot do that on the texts, and rarely is the attempt made. The “why not screen?” question is a reasonable conversational opener, but it should not be allowed to import a default that the New Testament does not.

The third assumption is that there is a settled “we” with shared moral objections. The pitch assumes a clear moral consensus among Christians about what to screen. There isn’t one. The screening industry itself doesn’t agree internally — and the disagreements are not at the edges; they are at the centers of the various screens. The “companies we have moral disagreement with” formulation works as conversational shorthand, but the moment you press it, the agreement evaporates. Which companies? On what grounds? Whose moral framework? Whose theological tradition? The screens that exist in the market reflect particular communities’ moral priorities at particular cultural moments. They are not a Christian consensus. The friendly “we” of the pitch is doing more work than the underlying moral landscape can carry.

The “why not?” question deserves an answer. The answer is that the question is built on three assumptions ordinary scrutiny and Scripture do not support. Once those assumptions are tested, the burden of proof shifts — back to where Paul put it in the first place.

Where This Leaves the Conscience-Led Screener

Let me say this directly, because it matters to readers who have already chosen to screen and have done so out of genuine conviction. None of this post is aimed at you.

If you have reflected on the question — including the texts and lines of argument above — and your conscience leads you to screen, you are exercising exactly the kind of Christian liberty Romans 14 establishes and honors. Each one should be fully convinced in his own mind (Rom. 14:5). Paul’s instructions to the Roman believer who would not eat meat are direct: that scruple is not a defect; it is a conscience that has not yet been persuaded otherwise, and it should not be overridden, mocked, or manipulated by stronger brothers carrying their freedom indelicately. The screening choice, made out of conviction, sits in that same theological space. The Christian who refuses to hold something he finds spiritually corrosive is doing a real and honorable thing, and the freer brother owes him respect — not pressure to abandon the conviction, and certainly not the assumption that his caution is somehow weaker faith.

The argument of this post has been about something else. It has been about the framework that takes a conscience option and markets it as the biblical standard — that implies the unscreened investor has fallen short of what faithfulness requires, that builds a financial industry on a theological promise the New Testament does not actually make. The pushback is at the framework level. It is not at the level of the individual Christian who, after honest reflection, has settled this question on the side of restraint.

There is a related concern that deserves naming, because the Romans 14–15 framework cuts both ways. The believer who has reflected and decided to screen should not be pressured by the unscreened investor to abandon the scruple. Equally, the believer who has reflected and decided not to screen should not be made to feel less faithful by the screener — or by the marketing of the industry built around the screen. The whole point of Paul’s argument in Romans 14–15 is that the stricter conscience and the freer conscience can sit together at the same table, both honoring God, neither binding the other. The pastoral failure happens in both directions when one tries to legislate the other.

The posture this post is arguing for is not less seriousness about how Christians use their money. It is more. Not less attention to the moral weight of stewardship. More. But seriousness of the kind Scripture actually calls for — which turns out to look different from the seriousness the screening framework promises.

Clean Already

The deepest answer to the felt need for a clean portfolio is not a portfolio strategy. It is the gospel.

The cleansing the gospel actually offers is not printed on a brokerage statement. It is positional — given by union with Christ to those who are in him. If anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come (2 Cor. 5:17). The Christian’s standing before God is not a function of which holdings appear on the year-end report. It is a function of union with the one who bore the uncleanness the steward could never wash off himself.

The Letter to the Hebrews makes the same move in language that maps almost directly onto the screening question. The old purity system, the writer argues, accomplished a real but limited cleansing — a
purification of the flesh through the blood of goats and bulls and the ashes of a heifer (Heb. 9:13). It could not do the deeper work. It could not purify the conscience. How much more, the writer continues, will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify our conscience from dead works to serve the living God (9:14). The conscience is the very thing the screening framework promises to clean. Hebrews 9 says the cleansing of the conscience comes from one place, and it is not the curated holdings list. It comes from the cross.

The screening framework’s central intuition — that a serious Christian cannot rest until the moral residue has been removed — is right about the need and wrong about the location. The residue the gospel removes is not commercial. It is sin. The cleansing the conscience needs is not portfolio-shaped. It is cross-shaped. And it was accomplished two thousand years ago, on terms no portfolio engineering can replicate or improve.

The steward who has settled this can hold a messy portfolio with open hands. Not because the holdings are clean. Because the steward already is.

That is a different kind of freedom than the screening pitch offers. It does not promise a list. It promises a standing — and from that standing, stewardship gets harder, not easier. The steward must engage what he holds, vote what he can vote, understand his ownership as the responsibility it actually is, and refuse to look for a methodology that lets him feel clean by walking out of the room. The first is the stewardship Scripture has been pressing toward from the opening pages of Genesis. The second is what the financial industry has learned to package for Christians who have grown tired of the difference.
