Antonio Grassi was a 17th-century Italian priest belonging to the Oratory of Saint Philip Neri. Born Vincenzo Grassi in Fermo, he joined the Oratorians in 1609 and was ordained in 1617. He was recognized for his deep piety, his extensive knowledge of sacred scripture, and his commitment to the teachings of Saint Philip Neri. Throughout his ministry in Fermo, he served as a dedicated confessor, a counselor, and a mediator between local factions, while also dedicating himself to charitable works and the spiritual education of children.
Life and ministry
After losing his father at age ten, Grassi received spiritual guidance from a mentor who had known Saint Philip Neri. He became a prominent figure in Fermo, where he was respected for his role as a mediator. His generosity toward the poor was so significant that it drew attention from his fellow Oratorians. He also maintained a strong devotion to the Marian shrines of Loreto, making annual pilgrimages to the site.
Veneration
Grassi was beatified by Pope Leo XIII on 30 September 1900, following an investigation into his heroic virtues and the verification of two miracles. He is commemorated in the Catholic Church, with his feast day observed on 13 December. His remains are interred in the Chiesa del Carmine in Fermo.
