Felix of Nicosia was an 18th-century Capuchin lay brother born Filippo Giacomo Amoroso in Sicily. Despite being illiterate, he demonstrated great persistence in joining the Order of Friars Minor Capuchin, eventually entering the novitiate in 1743. He spent much of his life in his hometown, serving as a quaestor to collect alms. Known for his deep devotion and ability to endure harsh treatment from his superiors, he was recognized for his spiritual discipline and his service to the sick during local epidemics.
