Feast Day: March 10
Pope Saint Simplicius, born in Tivoli, Italy, was the son of Castinus. He is widely recognized for his significant contributions during the end of the Roman Empire as the Pope and his works to defend the Council of Chalcedon against the Monophysite heresy. Simplicius assumed the papacy in 468 AD, a time when the Western Roman Empire was facing increasing challenges from barbarian invaders. Despite the social and political upheaval, Pope Simplicius dedicated himself to serving the Italian people and defending the Orthodox Christian faith. One of Pope Simplicius' major accomplishments was his defense of the Council of Chalcedon. The council, held in 451 AD, reaffirmed the orthodox belief in Christ's dual nature, fully human and fully divine, against the Monophysite heresy that claimed Christ had only one nature. As the Monophysite heresy gained influence especially in the Eastern Empire, Pope Simplicius championed the teachings of Chalcedon and defended the true nature of Christ. Additionally, Pope Simplicius confronted Emperor Leo's attempts to grant greater authority to the Patriarch of Constantinople, aiming to make them second only to the Pope in the Church's hierarchy. Simplicius firmly opposed this move, ensuring that the primacy of the Bishop of Rome, as the successor of Saint Peter and the Pope, remained intact. His steadfastness safeguarded the unity of the Catholic Church. Pope Simplicius also played an instrumental role in reintroducing order and organization to the administration of the sacraments in the local churches of Rome. He emphasized the importance of the sacrament itself rather than the physical location of its administration. This initiative helped rejuvenate the spiritual life of the faithful and reinforced the sacraments' centrality in Catholic worship. In addition to his administrative reforms, Pope Simplicius was a prolific builder. He constructed four large churches in Rome, leaving a lasting architectural legacy. These churches not only served as places of worship but also as symbols of the Church's endurance in turbulent times. Despite the turmoil of his era, Pope Simplicius fervently fought against the Arianism promoted by King Odoacer, a Germanic barbarian leader who ruled Italy at the time. Arianism was a heresy that denied the divinity of Christ and threatened the very core of Christianity. Pope Simplicius's steadfast opposition to Arianism helped protect the orthodox faith and strengthen the Catholic Church's foundation in the face of adversity. Pope Saint Simplicius died on 10 March, although his feast day was formerly celebrated on 2 March. His contributions to the Church were recognized even before the establishment of formal canonization procedures, making him a revered saint in the pre-congregation era. While the specific patronage associated with Pope Saint Simplicius is not widely recorded, his life and work exemplify his unwavering commitment to the faith, defense of orthodoxy against heresy, and dedication to the welfare of the Italian people during a tumultuous period in history.
