Biblically Responsible Investing: Screening Sin Stocks & Values-Aligned Portfolios
Quick Answer
"Biblically responsible investing" means evaluating companies based on their practices and values alignment, then choosing to include or exclude them from your portfolio accordingly. There is no single "biblical" portfolio, but many Christians screen out companies profiting from abortion, contraception, gambling, alcohol, or exploitative labor—a practice consistent with Christian stewardship and conscience.
The Scriptural Foundation
The Bible does not forbid stock ownership. But it does command that we be intentional about how we allocate resources. Proverbs 22:3 teaches, "The prudent see danger and take refuge, but the simple keep going and pay the penalty" (NRSV). Part of prudence is understanding what you own.
When you buy a stock, you own a fractional share of a company and its operations. If that company profits from activities contrary to your faith—abortion services, predatory lending, weapon manufacturing—your capital is funding it. That raises a conscience question: Should I own this?
Matthew 6:24 teaches, "No one can serve two masters; for a slave will either hate the one and love the other, or be devoted to the one and despise the other. You cannot serve God and mammon" (NRSV). Mammon here means wealth pursued and held without regard to its sources or purposes. A Christian investing purely for returns, indifferent to what companies do with that capital, is serving mammon.
What "Sin Stocks" Mean
"Sin stocks" are companies whose core business or major revenue streams come from activities many Christians consider immoral: tobacco, alcohol, gambling casinos, abortion providers or abortion-related services, pornography, predatory lending, etc.
In 2026, the most common sin-stock screens exclude:
- Abortion. Companies that provide or profit significantly from abortion services (Planned Parenthood, which is not publicly traded, but healthcare companies that perform abortions are).
- Contraception. Some Catholics and conservative Protestants exclude companies manufacturing contraceptives.
- Gambling. Casino operators, lottery ticket distributors, gambling apps.
- Pornography. Adult entertainment, sex trafficking facilitators.
- Predatory lending. Payday lenders, subprime auto lenders that trap borrowers.
- Weapon manufacturing. Defense contractors, firearms manufacturers.
- Alcohol and tobacco. Traditional sin-stock exclusions, though some investors allow these.
- Exploitative labor. Companies with credible evidence of child labor, forced labor, or sweatshop conditions.
The Practical Challenge
Here's the difficulty: Most large companies are diversified. Apple manufactures products in ethical conditions but also donates to Planned Parenthood. Coca-Cola produces soft drinks but also operates in countries with labor exploitation. Johnson & Johnson makes healthcare products but also invests in fertility treatments some Christians oppose.
A pure screen—excluding any company with any problematic activity—would leave you with precious few holdings. A realistic screen requires judgment: What is the company's primary business? Does it profit significantly from activities I oppose? Is there a better alternative?
Proverbs 14:15 teaches, "The simple believe everything, but the prudent give thought to their steps" (NRSV). Prudence here means making thoughtful compromises, not achieving impossible purity.
How to Screen
If you want to build a biblically-screened portfolio, follow these steps:
1. Define your values. Write down what you oppose: abortion? gambling? All alcohol? Be specific. Different Christians have different convictions, and that's okay.
2. Research fund providers. Mutual funds and ETFs exist for various faith-based screens:
- Ave Maria Catholic Values Fund (excludes contraception, abortion, gambling, etc.)
- Eventide Gilead Fund (Christian values focus)
- Praxis Mutual Funds (progressive Christian screening)
- USAA Faith-Based ETF (military-friendly, Christian screening)
These funds do the screening for you, at a modest cost (typically 0.50–1.00% annually—higher than plain index funds, but aligned with your values).
3. Supplement with individual stock research. If you own individual stocks, research companies on sites like MSCI ESG Ratings or Sustainalytics. Use their data to evaluate alignment with your values.
4. Accept imperfection. You will not achieve a perfect portfolio. Diversification requires holdings in some morally ambiguous companies. That's okay. The goal is faithful stewardship, not sinless perfection.
The Performance Question
Do biblically-screened portfolios underperform? Historically, no. Studies comparing faith-based funds to broad indexes show similar long-term returns (7–10% annually for diversified portfolios). Sometimes faith-based funds outperform; sometimes they lag. This suggests that ethical screening does not create a performance penalty—a strong argument for pursuing values-aligned investing.
The Conscience Question
Some Christians argue that screening investments is self-righteous: "God judges companies' sins, not your investment choices. Invest purely for returns and trust God."
But this misunderstands stewardship. Proverbs 22:3 teaches, "The prudent see danger and take refuge, but the simple keep going and pay the penalty" (NRSV). Part of prudence is asking, "Does this use of my capital align with my values?" If you own tobacco stock and oppose smoking, you're being illogical—profiting from the very harm you claim to oppose.
This is not self-righteous; it's consistent. Your money should align with your mouth.
For Tax-Advantaged Accounts
A practical note: tax-deferred accounts (401(k)s, IRAs) often have limited fund options, some of which may not align with your values. In these cases:
- Choose the best available option. If your 401(k) plan offers Vanguard or Fidelity funds, you may have socially responsible options within them.
- Allocate what you can control. If your employer plan is limited, focus on faith-based screening in your taxable accounts, where you have more choice.
- Advocate for better options. Request that your employer plan add faith-based or ESG funds. Many do, if asked.
A Practical Example
Suppose you have $50,000 to invest. Instead of a plain S&P 500 index fund, you could build this biblically-screened portfolio:
- 40% Ave Maria Catholic Values Fund ($20,000) — screens for Catholic values
- 30% Vanguard Total Bond Market (plain bonds) ($15,000) — diversification, lower volatility
- 20% Praxis International Equity (Christian values) ($10,000) — international diversification with values screen
- 10% Money market fund for emergency access ($5,000)
This portfolio has similar structure to a standard allocation but screens for values. The fees are slightly higher (ave Maria is ~0.7% vs. 0.04% for plain S&P 500), but the conscience alignment is priceless.
The Bottom Line
Biblically responsible investing is possible and increasingly accessible in 2026. It requires:
- Clarifying your values
- Choosing funds or stocks that align with them
- Accepting that perfect purity is impossible
- Rebalancing periodically to maintain alignment
None of this requires sacrificing returns or prudent diversification. It simply means being intentional about where your capital goes—a practice consistent with Christian stewardship and conscience.
As Paul wrote in Philippians 4:8–9, "Finally, beloved, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is pleasing, whatever is commendable, if there is anything worthy of praise, think about these things... and the God of peace will be with you" (NRSV). That same principle applies to investing: Seek what is honorable and just, and peace will follow.
