Religious Vocation and Public Service

Hernández sought to enter the priesthood on several occasions, entering the Farneta Charterhouse in Italy during 1908 and later attending the Pontifical Latin American College in 1913. Due to persistent health issues, he remained in the medical field as a Franciscan tertiary. He frequently provided free consultations to low-income patients, often purchasing necessary medicines using his personal funds. His life of service ended in 1919 in Caracas when he was struck by a motor vehicle while performing his duties during the Spanish flu pandemic.

Canonization and Legacy

Following his death, Hernández attained significant status as a figure of veneration across Latin America. The Catholic Church initiated the process toward sainthood in 1949, and he was declared Venerable in 1985. Pope Francis approved his beatification in 2020 after the recognition of a miracle involving a girl’s recovery. On 19 October 2025, Pope Leo XIV formally canonized Hernández in Vatican City. His remains are housed in the La Candelaria Catholic Church, and his influence continues through the Universidad Dr. José Gregorio Hernández in Maracaibo and national celebrations held on his birthday.
