Vatican ‘unequivocally’ condemns slavery, counters ‘partial narrative’ in UN resolution
The Vatican's top diplomat to the UN unequivocally condemned both modern and historical slavery. Archbishop Gabriele G. Caccia, the Holy See’s permanent observer, delivered a statement on March 25, the International Day of Remembrance of the Victims of Slavery and the Transatlantic Slave Trade. The Vatican's statement countered what it termed a "partial narrative" within a newly adopted UN resolution. The UN resolution, led by Ghana, denounced the transatlantic slave trade as "the gravest crime against humanity" and called for reparations by member states. The International Day of Remembrance marks the 1807 legal abolition of the slave trade by the United Kingdom.

A UN General Assembly resolution, adopted March 25, 2026, declared the transatlantic slave trade the "gravest crime against humanity" due to its scale, brutality, and lasting impacts.1 2
Led by Ghana, it highlighted historical laws, including 15th-century papal bulls like Dum Diversas (1452) and Romanus Pontifex (1455), as authorizing African enslavement.1 2
The resolution passed with 123 votes in favor, 3 against (Argentina, Israel, U.S.), and 52 abstentions, including EU nations and the UK.1 2
It called for reparations to affected nations and marked the International Day of Remembrance of Victims of Slavery.1
Archbishop Gabriele Caccia, Holy See's UN observer, stated the Vatican "unequivocally condemns slavery, including in its modern forms."1 2
He emphasized remembrance's role in upholding historical truth and legal accountability.1 2
Citing Pope Leo XIV's Dilexi Te, Caccia linked liberation of the oppressed to the Kingdom of God.1
He reaffirmed slavery as a crime against humanity under international law, per the Universal Declaration of Human Rights.1 2
Caccia described the resolution as containing a "partial narrative" that does not serve truth.1 2
The UN text cited papal bulls as codifying racialized enslavement, which the Vatican rejects.1 2
A 2023 Vatican statement disavowed these bulls (Dum Diversas, Romanus Pontifex, Inter Caetera) as political acts, not Catholic doctrine.1 2
It noted they failed to reflect indigenous dignity and were manipulated by colonial powers.1
Papal condemnations date to 1435, when Eugene IV excommunicated enslavers of Canary Islanders.1 2
Pope Paul III's 1537 Sublimis Deus declared involuntary enslavement of non-Christians contrary to natural law.2
Leo XIII in 1888, quoting St. Augustine, rejected human dominion over fellow humans.1 2
Figures like Bartolomé de las Casas and Francisco de Vitoria opposed abuses in the Americas.2
U.S. Ambassador Dan Negrea called the resolution "highly problematic," arguing it advances narrow agendas over UN peace goals.2
UN Secretary-General António Guterres urged removing barriers for African descendants' rights.2
Caccia, recently appointed nuncio to the U.S., delivered the statement amid his transition.1 2
Assess Catholic doctrine’s stance on slavery versus modern UN narratives
The Catholic Church's teaching on slavery has evolved from early toleration of certain forms within societal norms—while planting seeds of opposition through Gospel principles—to unequivocal modern condemnations of slavery and the slave trade as grave evils incompatible with human dignity. This development reflects a deepening understanding of Christ's liberation from sin and application to social injustices, culminating in declarations of certain slaveries as intrinsically evil. The provided sources richly document this trajectory but offer no direct references to modern United Nations (UN) narratives, such as those in the Universal Declaration of Human Rights (1948) or the Supplementary Convention on the Abolition of Slavery (1956), which broadly define and prohibit slavery, human trafficking, and forced labor as violations of fundamental rights. Without UN sources, a point-by-point comparison is not possible; however, the Church's mature doctrine aligns with universal prohibitions on slavery by emphasizing the equal dignity of all persons, created in God's image, while nuanced historical contexts distinguish it from absolutist retrojections.
Catholic doctrine never endorsed slavery as ideal but viewed it as a consequence of sin, permissible under natural law in limited forms (e.g., as punishment or war captive), yet always subject to Christian charity. St. Ambrose of Milan (c. 391) exemplified this by prioritizing liberality—redeeming captives, especially women and children—as the "highest kind" of mercy, urging clergy to outdo slavery's hardness with freedom. Scriptural paradigms, like Paul's Letter to Philemon, promoted loving treatment of slaves and spiritual equality ("neither slave nor free"), gradually undermining the institution without immediate abolition.
Medieval papal grants, such as Pope Nicholas V's Romanus Pontifex (1455), authorized Portugal to subdue non-Christians and reduce them to "perpetual slavery" in the context of just wars against Muslims and for evangelization, reflecting era-specific geopolitical realities rather than doctrinal endorsement of chattel slavery. Critics note these were politically linked, not core faith expressions, later repudiated. No Father, Doctor, pope, or council issued a "comprehensive condemnation" of all slavery initially, but the Church softened its effects: upholding slave rights, banning Native American enslavement, and founding orders like the Mercedarians and Trinitarians for prisoner redemption.
By the 16th century, popes shifted decisively. Pope Paul III's Sublimis Deus (1537) declared indigenous peoples "truly men" capable of faith, prohibiting their enslavement: "they may and should, freely and legitimately, enjoy their liberty... nor should they be in any way enslaved." This nullified contrary claims, prioritizing evangelization through example over coercion.
The 19th century marked stronger apostolic interventions. Pope Gregory XVI's In Supremo Apostolatus (1839) condemned the African slave trade as "absolutely unworthy of the Christian name," prohibiting any defense of it and reproving reductions to servitude treating Blacks "as if they were not men but rather animals." Pope Leo XIII's In Plurimis (1888) deemed slavery a "penalty upon the sinner," unnatural for humans destined for dominion over beasts alone, and decried its revival in colonies via Ethiopian slave imports and indigenous oppression. He invoked St. Gregory the Great: manumission restores God-given freedom. Catholicae Ecclesiae (1890) praised predecessors like Paul III and Gregory XVI for eliminating slavery "wherever it existed," guarding against its return. Pope Pius X's Lacrimabili Statu (1912) reserved absolution for enslavers of Indians, echoing prior bulls.
These built on prior efforts, prodded by external pressures (e.g., British requests), but rooted in maturing theological insight.
Post-Vatican II, Gaudium et Spes (1965) listed "slavery" (servitus) among "shameful and offensive" social evils. Pope John Paul II's Veritatis Splendor (1993, n. 80) echoed this verbatim, classifying slavery (with deportation) among acts intrinsically evil—wrong always and everywhere, independent of circumstances. His Goree Island speech (1990) confessed slavery as a "sin of man against God." Recent Dicastery statements (2023) affirm popes' condemnations of violence and slavery against indigenous peoples, rejecting the "doctrine of discovery" (linked to 15th-century bulls) as non-doctrinal, politically manipulated, and inadequate to human dignity. Pope Francis urged: "Never again... coercing others."
Pope Leo XIV's Dilexi te (2025) continues this, highlighting redemption orders combating "modern forms of slavery: human trafficking, forced labor, sexual exploitation," as paschal signs of Christ's freedom.
Lawrence J. Welch's 2006 evaluation of John T. Noonan's A Church That Can and Cannot Change critiques claims of doctrinal reversal. Noonan argued slavery shifted from tolerable to intrinsically evil (contra Newman), enabling changes elsewhere (e.g., contraception). Welch counters: Veritatis Splendor's servitus lacks definition, mirroring Gaudium et Spes' vague usage—not encompassing all historical forms (e.g., mitigated servitude vs. absolute chattel slavery). Paul, Fathers, and popes distinguished; no evidence John Paul II intended total reversal. Developments occurred (e.g., chattel slavery condemned), but not "revolution" erasing prior truths. This aligns with Newman's development theory: organic growth, not contradiction.
Catholic doctrine consistently opposes slavery's core evil—violation of human dignity—through progressive clarification, now deeming unjust forms intrinsically evil. This fidelity to Christ's liberating mission distinguishes it from static views, offering a model of moral development. Absent UN sources, the Church's stance appears convergent with global anti-slavery consensus, emphasizing redemption and rights for all peoples.
