What is morally responsible investing — and how is it different from ESG?
“Morally responsible investing” turns up in Catholic financial conversations more and more, usually without anyone explaining what it actually involves. If you have heard the term and wondered whether it is a real discipline or a marketing label, here is a plain answer: what it is, where it differs from ESG, and the trade-offs you should be told about before you commit.
What is morally responsible investing?
Morally responsible investing (MRI) builds an investment portfolio around Catholic moral principles. In practice that means two things. First, avoidance: declining to hold companies whose primary business conflicts with Church teaching. Second, for some investors, active ownership: keeping a shareholder position and using it to vote, file resolutions, and press management toward change.
The point is not to feel better about a statement. It is to stop unknowingly funding work you would never choose to fund, and to do it without wrecking the portfolio in the process.
What does it screen for?
The most widely used Catholic reference point is the Socially Responsible Investment Guidelines published by the United States Conference of Catholic Bishops, updated in 2021 for the first time in eighteen years. They organise the concerns into five areas: protecting human life, protecting human dignity, enhancing the common good, pursuing economic justice, and caring for creation.
Underneath those headings, common avoidance screens include abortion and related life issues, pornography and adult entertainment, predatory lending, and companies with serious human-rights problems. Some investors add positive tilts toward work they want to support.
Worth knowing, because a great deal of writing on this blurs it: those Guidelines govern the bishops’ own funds. They are not binding on individual Catholics. Institutions and families adopt them by choice. That is what makes them genuinely useful as a starting point rather than a rulebook — the reasoning is public and carefully done, and the decisions stay where they belong, with your conscience.
How is MRI different from ESG?
The mechanics rhyme. Both say “we will not simply buy everything.” The difference is whose principles set the screens.
| ESG | Morally responsible investing (MRI) | |
|---|---|---|
| Organising principle | Environmental, social, governance criteria | Catholic moral principles |
| Typical screens | Carbon, labour practices, governance, board composition | Life issues, pornography, predatory lending, human dignity |
| Who sets the criteria | Ratings frameworks and fund providers | The investor’s conscience, commonly guided by the bishops’ guidelines |
| Life issues | Generally not addressed | Usually the first and firmest screen |
That last row is the one that matters most to Catholic families, and it is why “just use an ESG fund” is not an answer. An ESG rating can score a company highly on carbon and governance while saying nothing at all about the thing you actually care about.
And how is it different from biblically responsible investing?
Close cousins. Biblically responsible investing (BRI) is the term used mostly in evangelical Protestant circles; MRI is the Catholic term. The screens overlap heavily — life issues and adult entertainment appear in both — but the reasoning differs, and so does the emphasis. Catholic social teaching puts weight on economic justice and the common good in ways a BRI screen may not, and the bishops’ guidelines pair avoidance with active ownership rather than avoidance alone.
If you want the Protestant framing for comparison, we have written about biblically responsible investing separately.
What are the honest trade-offs?
Any screened portfolio holds a different mix than the whole market, so it will track a conventional benchmark with some difference over time. Sometimes a little ahead, sometimes a little behind. That is not a flaw to be talked around; it is simply what screening means.
What matters far more than the screening is the construction. A well-built screened portfolio is diversified, low-cost, and broadly behaves like the market over long periods. A poorly built one is concentrated and expensive, and can lag for reasons that have nothing to do with conviction.
So the question to ask any advisor is this: can you show me the expected tracking error against a conventional benchmark before I commit? A good one can, and will, in writing.
How Angelus approaches it
We put the screens in your written investment policy before anything is bought, alongside the target allocation, the rebalancing rule, and which accounts hold what for tax purposes. You see the expected trade-off first. And screening stays an option rather than a condition — plenty of families run a conventional portfolio and direct their convictions toward giving and legacy instead. Both are real choices, made on purpose.
If you want to see how your current funds line up, the portfolio values screening is free and carries no obligation. Or read more about how we work with Catholic families.
