Catholic Social Teaching does not offer technical formulas, but it does provide solid and enduring principles to guide human action in the economic sphere. Faith is not an optional add-on to investing; it is its moral compass.

For this reason, investing in coherence with one’s faith requires two inseparable dimensions:
• Structuring the portfolio according to objective principles.
• Living investing as a vocation that requires virtues.

Below, we develop ten key concepts: the first five are structural foundations for building portfolios consistent with the faith; the next five are virtues that every Christian investor should cultivate.

The Structural Foundations of a Faith-Consistent Portfolio

• The Dignity of the Human Person

The dignity of the human person is the indispensable and non-negotiable principle of all Catholic investing. The human person is always an end in himself or herself, and never a means at the service of economic profit.

This principle requires companies to place the human person at the center and, through their activities and corporate practices, to safeguard the dignity of both their employees and their customers.

Faith-consistent investing therefore places human dignity at the center of business analysis, in a stable and objective manner.

• The Protection of Life

Human life, from conception to natural death, is inviolable. Therefore, faith-consistent investing excludes companies involved in abortion, embryonic research, euthanasia, or industries that directly attack human life.

Catholic investors cannot detach themselves from the ultimate use of their capital. Responsible Catholic investing requires genuine coherence, not ambiguous compromises.

• The Protection of the Family

The family, founded on marriage between one man and one woman, is the basic cell of society.
A faith-consistent investment portfolio should avoid companies that promote models contrary to Christian anthropology or that systematically erode the institution of the family.

• Care for Creation

Care for creation is not environmental ideology, but a moral responsibility.
Ethical investing from a Catholic perspective requires assessing the environmental impact of companies, without falling into the ideological simplifications typical of certain ESG approaches.

The guiding criterion is intergenerational responsibility. Creation is both a gift and a task.

• The Common Good

The common good is the principle that harmonizes all the others.
It is not enough for a company to be profitable. It must contribute positively to integral human development.

A Catholic investment portfolio should be structured with a long-term vision, recognizing that profit is legitimate—but never absolute.

The Virtues of the Christian Investor

Structure is necessary, but not sufficient. Without personal virtue, there is no true coherence.

• Prudence

Prudence is the virtue that enables one to discern the concrete good in each situation.
In Christian investing, it involves analyzing risks, understanding markets, and avoiding impulsive decisions. Good intentions are not enough; technical competence is required.

Prudence calls for proper formation and the support of investment firms that integrate ethics and professionalism.

• Justice

Justice leads us to give each person his or her due. The Catholic investor does not seek only to maximize returns, but to participate in building a more just economy. This includes the responsible exercise of shareholder voting and dialogue with companies.

Faith-consistent investing includes active engagement.

• Fortitude

Fortitude enables investors to uphold ethical criteria even when the market pressures them otherwise.
There will be highly profitable sectors that are not morally acceptable. Fortitude sustains coherence when it entails economic sacrifice.

Without fortitude, Catholic investing dissolves into opportunism.

• Temperance

Temperance moderates the disordered pursuit of profit. The market encourages immediacy and speculation. The Christian investor is called to a calm, long-term vision, avoiding greed and short-termism.

• Responsibility

To invest is to exercise co-responsibility for the world. Capital is not neutral. It shapes culture, companies, and social structures. For this reason, Catholic investing is a concrete form of apostolate in the economic sphere. It requires awareness, formation, and appropriate tools.

Faith, Structure, and Virtue

Catholic Social Teaching is not a list of prohibitions. It is a comprehensive vision of the human person and of the economy.

Authentic Catholic investing combines:

• Objective principles to structure faith-consistent portfolios.
• Personal virtues to live by investing as a vocation.

When faith and finance are integrated, the market ceases to be a neutral space and becomes a field of witness.

The Social Teaching of the Church (STC) provides a stable, profound, and coherent moral framework for discerning where and how to invest. This guide aims to show how to apply these principles in a practical, professional, and rigorous way—without renouncing profitability or financial excellence.

What Is Faithful Investing and Why Is It Essential for Catholic Investors?

Faithful Investing—or faith-consistent investing—is an investment approach explicitly based on the principles of the Social Teaching of the Church. Unlike generic ethical investing or socially responsible investing, Faithful Investing does not rely on changing criteria or volatile cultural consensus. Instead, it is grounded in objective and immutable principles.

From this perspective, investing ceases to be a neutral act. Every financial decision implies supporting certain business models and social structures. For this reason, Catholic investing requires moral discernment and responsibility.

The Social Teaching of the Church as the Foundation of Catholic Investing

The Social Teaching of the Church is not a technical manual of economics, but a moral compass. It reminds us that money is not an end in itself but a means, and that the economy is not an autonomous system detached from ethics. It is called to serve the human person and contribute to the common good.

The STC provides principles that illuminate human action also in the financial sphere. Saint John Paul II, in Centesimus Annus, reminded us that when the economy is separated from its moral dimension, it ultimately destroys itself.

Applied to finance, the Social Teaching of the Church reminds us that:

• Money is a means, not an end
• Profit is legitimate, but must be ordered toward the common good
• Economic structures must be at the service of the human person

Therefore, ethical investing from a Catholic perspective cannot be limited to maximizing returns without considering the real impact of the companies being financed.

Altum Investment Guidelines: The Four Pillars of Faith-Consistent Investing

At Altum Faithful Investing, we have drawn upon the teachings of the Social Teaching of the Church to develop our Altum Investment Guidelines. Through them, we seek to integrate Christian values into every investment decision, following four fundamental pillars: Promotion of Life, Promotion of the Family, Promotion of Human Dignity, and the Care and Protection of Creation.

These principles not only guide our decisions but also provide a clear framework for building investment portfolios that are fully aligned with the Catholic faith, without compromising financial objectives.

1. Respect for Life

At Altum, all our decisions are rooted in absolute respect for human life, from its beginning at conception to its natural end. The Social Teaching of the Church affirms the sacred and inviolable character of life, which leads us to exclude any investment in companies whose activities contradict this essential principle.

2. Human Dignity

The Social Teaching of the Church places the dignity of the human person at its very core. Every human being is created in the image and likeness of God and therefore deserves full respect in all circumstances.

3. Family

The family, as the basic institution of society, is another central axis guiding Altum’s investment decisions. Its protection and strengthening must be promoted in all areas of social and economic life.

4. Care for Creation

Pope Francis’ encyclical Laudato Si’ emphasizes that the protection of the natural environment is both a moral and spiritual responsibility. At Altum, we understand care for creation as an indispensable element for achieving true social justice, since natural resources are not merely material assets but gifts from God entrusted to our responsible stewardship.

Professional Investing Tools at the Service of Ethical Discernment

For many years, the main obstacle for Catholic investors was the lack of reliable information. Today, this has changed thanks to professional investing tools specifically designed for Catholic investing:

• For professional investors, Altum Explorer provides easy access to comprehensive, rigorous, and transparent analysis of thousands of global companies.
• For individual investors, the Altum App allows companies to be evaluated using the same criteria, making it easier to build portfolios that are fully aligned with the faith.

The Social Teaching of the Church reminds us that faith must permeate all aspects of life, including economic decisions. Faithful Investing is not a renunciation, but a call to coherence.

Investing well is not only about achieving returns, but about investing with meaning. Because every euro invested is also a vote for the kind of world we want to help build.
