Blessed Iuliu Hossu (1885–1970) was a Romanian Greek-Catholic bishop and cardinal renowned for his unwavering faith, national unity efforts, and courageous resistance against totalitarian regimes. Born on January 30, 1885, in Milaș, then part of Austria-Hungary, he pursued theological studies in Rome, earning doctorates in philosophy and theology. Ordained a priest in 1910, Hossu served as a military chaplain during World War I. In 1917, he was appointed Bishop of Gherla (later Cluj-Gherla). Notably, on December 1, 1918, he read the Declaration of Union at the Great National Assembly in Alba Iulia, marking Transylvania's unification with Romania. His episcopal motto, “Our faith is our life,” encapsulated his steadfast commitment to both spiritual and national causes.‍

During World War II, Hossu actively opposed the persecution of Jews in Northern Transylvania, urging his faithful to assist them, actions that saved thousands of lives. His efforts have led to considerations for recognition as “Righteous Among the Nations.” Following the Communist regime's rise in Romania, Hossu refused to sever ties with the Vatican, leading to his arrest in 1948. He endured imprisonment in Sighet Prison and years of house arrest at Căldărușani Monastery. In 1969, Pope Paul VI secretly appointed him cardinal in pectore, a title revealed only after Hossu's death on May 28, 1970.‍

Recognized for his martyrdom and unwavering faith, Pope Francis beatified Hossu on June 2, 2019, in Blaj, Romania, alongside six other Greek-Catholic bishops persecuted under Communism.
