Daily Saint

St. Damasus served as pope between 366 and 384 A.D., guiding the Church in an era of doctrinal conflict, political turmoil, and the consolidation of Christian identity in the Roman world.

His parents were from Lusitania (part of modern-day Spain/Portugal) and moved to Rome either before or soon after the future saint was born. From an early age, St. Damasus devoted himself to serving the Church. He became a deacon and was later ordained as a priest during times of strained relations between the Church and the State.

When Pope Liberius died in 366, St. Damasus was elected Bishop of Rome. The deacon Ursinus and his supporters contested the election, claiming their own right to the office. The conflict escalated into violence that led to bloodshed. Emperor Valentinian I banished Ursinus from Rome, and St. Damasus ascended to the Chair of Peter.

St. Damasus faced many challenges during his pontificate. He fought and condemned heresies such as Arianism, Apollinarianism, and Macedonianism, core teachings of the Church. He also addressed the tensions and threats of schism between the Eastern and Western Churches, as well as questions regarding the authority of the Roman Church.

Among St. Damasus’s principal achievements was his commissioning of St. Jerome’s translation of the Scriptures into Latin, which became the Latin Vulgate. He also established the Liturgy in Latin, restored the Catacombs in Rome to promote veneration of the martyrs, and defined the canon of Scripture at the Council of Rome in 382.

Pope St. Damasus is venerated in both the Catholic Church and the Eastern Orthodox Church.

What were the heresies St. Damasus opposed, and why were they important?

Pope St. Damasus opposed several heresies of his time, notably Arianism, Apollinarianism, and Macedonianism. Challenging these teachings was vital because they undermined the doctrine of the Trinity and the comprehensive Christian understanding of God as revealed in Scripture and Tradition. St. Damasus helped bring clarity and orthodoxy during a period of theological disputes.

What role did St. Damasus have in shaping the canon of Scripture?

St. Damasus presided over the Council of Rome in 382. He had a vital role in deciding what books would be included in the canon of Scripture. He also supported St. Jerome in revising his Latin translations of Scripture. The project resulted in the Latin Vulgate, a translation that would become standard in Western Christianity.

Did the Eastern and Western Churches separate during St. Damasus’s pontificate?

Although the Eastern and Western Churches did not entirely break communion during St. Damasus’s pontificate, questions about the authority of the Bishop of Rome and periods of non-communication created division. Later schisms included the Acacian Schism, which lasted 35 years from 484, the Photian Schism, which lasted four years from 867, and the Great Schism of 1054, which remains in effect today.
