Church in European Union calls for preserving outer space as the common heritage of humanity
COMECE and Caritas in Veritate Foundation organized a conference in Brussels on June 9 titled “Outer Space: A New Frontier of the Common Good.”. The event gathered Catholic Church representatives, EU officials, diplomats, academics and experts to discuss the ethical, political and strategic implications of outer space governance amid increasing involvement of states and private actors. Speakers stressed the need for international cooperation to keep outer space a common heritage, citing the 1967 Outer Space Treaty and concerns over space debris, congestion and militarisation. The conference highlighted EU initiatives such as a proposed EU Space Act, a European Space Shield and investment programmes, while emphasizing moral principles of responsibility, solidarity and respect for future generations.

The Catholic Church’s Commission of the Bishops’ Conferences of the European Union (COMECO) and the Caritas in Veritate Foundation convened a high‑level conference in Brussels on 9 June 2026 titled “Outer Space: A New Frontier of the Common Good.” The gathering brought together Church officials, EU representatives, diplomats, academics and experts to discuss the ethical, political and strategic dimensions of space governance as the sector expands with both state and private actors. 1
COMECO highlighted that outer space is rapidly becoming a focal point for strategic, economic and scientific activity. Established space powers are increasing their ambitions, while many other nations seek to develop or expand their presence. At the same time, private companies are playing an ever larger role in satellite deployment, exploration and commercial ventures, reshaping the existing governance framework. 1 2
Archbishop Ettore Balestrero, the Holy See’s permanent observer to the United Nations, opened the conference and stressed that space must not become a “jungle” or a “law‑less frontier” governed by “first‑come, first‑served” principles. He called for a human‑centered approach rooted in responsibility, solidarity and respect for subsidiarity, echoing the 1967 Outer Space Treaty’s vision of space as the “province of humankind” for peaceful and sustainable use. 1
Father Manuel Barrios Prieto, COMECE secretary‑general, pointed to the European Union’s growing responsibility, citing proposals such as an EU Space Act, the development of a European Space Shield and increased investment in space programmes. These measures, he argued, could help steer the sector toward the common good and mitigate risks such as space debris, low‑Earth‑orbit congestion and the militarisation of space. 1
The Caritas in Veritate Foundation presented its publication “Outer Space and Humanity at a Crossroads: Reflections on a New Frontier of the Common Good,” offering interdisciplinary ethical analyses and concrete recommendations. Participants stressed the need for governance frameworks that balance technological innovation, security concerns and the duty to safeguard the common good for present and future generations. 2
Both speakers and attendees reaffirmed the importance of fostering international dialogue and cooperation to ensure that outer space remains a shared heritage that contributes to the flourishing of the entire human family. The conference forms part of COMECE’s ongoing effort to link the Catholic Church, EU institutions and civil society on emerging policy challenges affecting humanity’s future. 1 2
Is outer space a common heritage requiring Catholic moral governance?
Yes. Catholic teaching—while not speaking in the exact technical language of international law—does hold that outer space is not morally “neutral” or merely a commercial frontier, but a shared environment that must be governed for peace, justice, solidarity, and the common good, with special attention to stewardship for present and future generations.
In addresses to the United Nations, the Holy See explicitly frames outer space as a “common good”—meaning the benefits of peaceful use should flow to all States, not just those with advanced capabilities.
The Holy See also calls outer space “part of our common home” and states that every State has a duty to safeguard it “responsibly as steward for present and future generations.”
So, if by “common heritage” you mean something like belonging to humanity in a way that imposes moral duties on users and governments, Catholic moral principles clearly apply: stewardship and shared responsibility come first.
Catholic statements link the need for governance to several moral risks of unregulated exploitation or rivalry:
Pope Paul VI warned that technological progress is not automatically matched by progress in morality and law, and he urged a “whole body of ‘space law’” with legal frameworks and institutional arrangements so that space achievements serve the common good and are “protected against abuse.”
The same theme appears in later Holy See statements: governance should ensure that activity in this shared environment advances humankind, justice, and peace and avoids a drift into “confusion and rivalry.”
The Holy See argues it is essential that outer space remain non-militarized permanently for peaceful purposes, and it highlights how weaponization and related tests endanger space as a shared environment.
Catholic governance is also concretely ethical: protecting the space environment includes limiting and removing space debris, because current practices threaten the sustainability of peaceful uses.
Paul VI explicitly warned against using space benefits “to the profit of only one group of nations to the exclusion of the others,” and called for a system where space resources serve advancement of mankind, justice, and peace.
Similarly, the Holy See says space governance should ensure benefits reach all States, including those with limited resources, and that commercial use should not deepen existing inequalities.
Catholic moral teaching here is not that the Church drafts spacecraft regulations or technical standards. Rather, the Church asserts moral principles that should inform public authority and international cooperation—especially:
That is why the Holy See repeatedly supports multilateral forums and international arrangements for managing space activities as “global commons.”
Outer space can fairly be described, in Catholic moral terms, as a shared inheritance of humanity that entails duties of stewardship, justice, and peace—and therefore calls for responsible governance rather than unilateral exploitation or competitive militarization.
