What Is Faith-Based Investing? A Guide to Biblically Responsible Investing

Faith-based investing is the practice of aligning an investment portfolio with religious convictions. For Christian investors, this most often takes the form of biblically responsible investing, a discipline that applies scriptural principles to the selection of individual securities. The approach has grown from a niche practice into an established category of values-aligned investing, with dedicated funds, screening methodologies, and research infrastructure behind it.

This guide explains what faith-based investing involves, how it differs from adjacent approaches like ESG, how biblically responsible screening actually works at the security level, and how an investor can put the discipline into practice.

Faith-based investing and biblically responsible investing

The two terms are often used interchangeably, and the overlap is real, but the distinction matters. Faith-based investing is the broad category: any investment approach guided by religious values, across any tradition. Biblically responsible investing, usually abbreviated BRI, is the specifically Christian discipline within that category. BRI applies guidelines derived from Scripture to investment selection, avoiding companies whose products or practices conflict with biblical teaching and favoring companies whose conduct reflects principles of justice, integrity, and care for human dignity.

BRI also differs from ESG investing, with which it is frequently confused. ESG frameworks score companies on environmental, social, and governance criteria defined by secular institutions, and the resulting screens can diverge sharply from Christian conviction on questions like the sanctity of life and religious liberty. An investor can hold an ESG fund and still own companies that a biblical screen would exclude. The reverse is also true. The frameworks answer different questions, which is why investors who care about biblical alignment generally cannot substitute one for the other. For a closer look at how values screens differ, see our explainer on environmentally responsible investing.

How biblically responsible screening works

Screening operates in two directions. Negative screening excludes companies involved in activities that conflict with biblical values. Common exclusions include abortion and abortifacient products, pornography and adult entertainment, gambling, and companies whose conduct demonstrates exploitation of workers or communities. Positive screening works in the opposite direction, identifying companies whose business practices reflect values a Christian investor wants to support: fair treatment of employees, honest governance, and products and services that contribute to human flourishing.

The level at which screening happens matters as much as the criteria. Fund-level screening evaluates a fund's stated mandate; security-level screening evaluates every individual company inside a portfolio. Security-level screening is the more rigorous standard, because broad index funds and many actively managed funds hold hundreds of companies, and a fund's name or mission statement reveals little about what sits inside it. Investors who want confidence that every holding passes a biblical screen need visibility down to the individual security. Monorail's screening applies at that level: every company receives an Impact Score reflecting how it performs against values-based criteria, so an investor can see exactly what a portfolio holds and why. Our overview of ETFs and how they are constructed explains why fund wrappers can obscure what an investor actually owns.

The biblical foundation: stewardship

The theological case for BRI rests on stewardship. Scripture teaches that everything belongs to God and that people are entrusted with managing what they hold (Psalm 24:1). On that view, investment capital is not morally neutral. Owning shares of a company means owning a fraction of its business, participating in its profits, and funding its activities. The stewardship question is whether a believer can consistently profit from conduct that Scripture calls them to oppose. BRI answers that alignment between conviction and capital is part of faithful management, in the same way that honest dealing and generosity are.

This is a conviction about consistency rather than a claim about outperformance. Biblically responsible portfolios are built with the same professional discipline as conventional portfolios, including diversification, risk management, and cost control. The screen defines the eligible universe; sound portfolio construction does the rest.

The unexamined portfolio

Most investors have never audited their holdings against their values. Retirement accounts, brokerage accounts, and employer plans commonly hold index funds and diversified mutual funds, and inside those wrappers sit companies the account holder has never evaluated and would not knowingly support. The gap is structural: the fund industry optimizes for broad exposure at low cost, and values alignment has never been part of that mandate.

The practical first step in faith-based investing is finding out what you currently own. Monorail's Investment Analyzer screens existing holdings against values-based criteria and shows how each company scores, which turns an abstract concern into a specific, reviewable list. From there, an investor can decide what to keep, what to replace, and what standard to apply going forward.

Putting it into practice

There are two broad paths, and they are not mutually exclusive.

The first is professionally managed investing. Monorail offers managed portfolios built on biblically screened holdings, constructed and monitored with institutional methodology and available across risk allocations suited to different goals and time horizons, including retirement accounts. This path suits investors who want the screening discipline without managing individual positions.

The second is self-directed investing with screening data in hand. Monorail's stock trading tools surface the Impact Score on every security before purchase, so an investor building their own positions can apply a biblical screen to each decision.

Common questions

Does faith-based investing require sacrificing returns?

Screening changes the eligible universe of investments; it does not change the principles of sound portfolio construction. Academic and industry research on values-based screening shows a range of outcomes depending on methodology and period studied, and no investment approach can guarantee results. What screening reliably delivers is alignment: certainty about what your capital supports.

Is BRI the same as ESG?

No. ESG criteria are defined by secular institutions and frequently conflict with biblical convictions on specific issues. BRI derives its criteria from Scripture. Portfolios built under the two frameworks can look very different.

How do I know whether my current investments align with my values?

Run them through a security-level screen. The Investment Analyzer evaluates existing holdings against values-based criteria and shows the result company by company.
