June 25, 1938: Humani generis unitas (Unissued Encyclical Draft)

On June 25, 1938, as Nazi “Aryan” ideology tightened its hold on Germany and racial theories spread through Europe, Pope Pius XI quietly initiated a rare, covert response. In Rome, he summoned American Jesuit John LaFarge, a priest known for opposing segregation in the United States, and tasked him with helping draft an encyclical condemning racism and antisemitism. The secrecy reflected both the political danger of the moment and the internal complexity of Vatican diplomacy, as totalitarian powers increasingly pressured the Church’s public voice.

LaFarge traveled to Europe and worked with other Jesuit scholars to prepare what became known as Humani generis unitas (“The Unity of the Human Race”). Though never officially promulgated, the draft affirmed the God-given dignity of every person and rejected racial supremacy as incompatible with Christian truth. It held that humanity is not divided into spiritual “castes,” but bound together under one Creator and one moral law. The document’s very existence signaled a conscience formed by Scripture and the historic conviction that every human life bears divine imprint.

LaFarge’s role was marked by moral courage and pastoral clarity. His earlier opposition to segregation made him an unusual choice: an American priest shaped by firsthand knowledge of racial injustice, now called to address the world’s accelerating descent into racist idolatry. The project also highlights the quiet heroism often required in eras of fear—work done without applause, under constraints, in trust that truth is never wasted.

Resistance within the Vatican delayed action. Some feared diplomatic fallout; others doubted the prudence of direct confrontation. Pius XI died in February 1939 before the encyclical could be issued, leaving the draft unfinished and largely unknown for years. Yet even as an unrealized public statement, it stands as a witness: faith does not merely comfort; it compels.

Scripture speaks with similar moral directness: “So God created man in His own image… male and female He created them” (Genesis 1:27). And, “From one man He made every nation of men… that they should inhabit the whole earth” (Acts 17:26). In a world tempted to measure worth by bloodlines and banners, the Church’s call remains to honor the image of God, love neighbor without partiality, and resist every ideology that denies the unity of the human family.
