During World War I, while serving on the Italian front, Ivan Merz wrote in his diary: “It would be horrible if this war had no spiritual benefit for me. I must not live the same way I lived before. … Let the Lord alone help me.”

Born in Banja Luka, Bosnia, to a nominally Catholic father and a Jewish mother, Merz was drawn to the Catholic faith through his high school teacher Ljubomir Maraković, a literary critic. He completed a year of university study in Vienna before being drafted into the Austro-Hungarian army in 1916. At the front, often unable to receive the sacraments, he committed himself to daily prayer and the pursuit of holiness.

After the war, Merz continued his studies in Vienna and later in Paris, where he spent two years serving the poor through the Society of St. Vincent de Paul, made a pilgrimage to Lourdes, and was influenced by writers such as Jacques Maritain, Paul Claudel and Charles Péguy.

In the years that followed, he helped organize the Croatian Catholic youth movement and promoted Catholic Action under the motto “Sacrifice, Eucharist, Apostolate.” In 1923, he completed a doctorate at the University of Zagreb and began teaching French language and literature. Deeply devoted to the Sacred Heart of Jesus, he centered his life on daily Mass and Eucharistic adoration.

Suffering from chronic eye disease and sinus infections, Merz underwent surgery in April 1928. He contracted meningitis and was left unable to speak. When a priest administering the last rites asked whether he offered his life for the youth he served, he nodded in assent. He died May 10, 1928, at age 31, and was beatified by St. John Paul II in 2003.
