POPE #38
Pope St. Siricius
The 38th Pope of the Catholic Church
St. Siricius
Pope St. Siricius was one of the most influential administrative popes of the early Church. While his predecessor, St. Damasus I, strengthened the authority of Rome through Scripture and doctrine, Siricius helped establish how the universal Church would be governed.
He is especially remembered as the first pope whose surviving official letters (decretals) carried the force of universal papal law. These decretals answered questions from bishops across the Christian world regarding doctrine, discipline, and Church governance, establishing a model that future popes would follow for centuries.
“Take heed to thyself and to doctrine: be earnest in them. For in doing this thou shalt both save thyself and them that hear thee.”

Overview
Pope St. Siricius was one of the most influential administrative popes of the early Church. While his predecessor, St. Damasus I, strengthened the authority of Rome through Scripture and doctrine, Siricius helped establish how the universal Church would be governed.
He is especially remembered as the first pope whose surviving official letters (decretals) carried the force of universal papal law. These decretals answered questions from bishops across the Christian world regarding doctrine, discipline, and Church governance, establishing a model that future popes would follow for centuries.
His pontificate also witnessed the final collapse of Arianism within the Roman Empire and the continued strengthening of Catholic orthodoxy under Emperor Theodosius I.
Early Life
Very little is known about Siricius’ early years.
He was born in Rome and served as a deacon under Popes Liberius and St. Damasus I.
Because of his long service in the Roman Church, he became widely respected for: sound doctrine, administrative skill, pastoral wisdom, loyalty to the Apostolic See.
By the time of Damasus’ death, Siricius was already one of the most experienced clergy in Rome.
Becoming Pope
Following the death of Pope St. Damasus I on December 11, AD 384, Siricius was elected Bishop of Rome with broad support.
Unlike the disputed election of Damasus nearly twenty years earlier, Siricius’ election was comparatively peaceful.
He inherited a Church that was: doctrinally united after Constantinople, rapidly expanding, increasingly organized, facing new pastoral and disciplinary questions.
The age of persecution had ended.
The challenge now was governing a worldwide Church.
The First Papal Decretals
Siricius’ most enduring contribution came in AD 385.
A Spanish bishop named Himerius of Tarragona wrote to Rome seeking guidance on numerous pastoral issues.
Rather than giving a private opinion, Siricius issued a formal written response.
Known as the Directa ad decessorem, it is the earliest surviving papal decretal.
The pope answered questions concerning: Baptism Confirmation Ordination Clerical discipline Marriage Penance Church governance Most importantly, Siricius expected these directives to be observed throughout the Church.
This established an important precedent: The Bishop of Rome exercises not only doctrinal authority but also universal pastoral governance.
Clerical Celibacy
One of Siricius’ best-known teachings concerned the discipline of clerical continence.
He reaffirmed the long-standing expectation that: bishops, priests, and deacons who were married before ordination were to live in perpetual continence after receiving Holy Orders.
It is important to understand the historical distinction: Siricius did not invent priestly celibacy.
Rather, he reaffirmed an earlier apostolic discipline already practiced in many parts of the Church.
The discipline concerning celibacy would continue developing throughout later centuries.
Defending Orthodoxy
Siricius continued defending the Church against several theological errors.
These included: Jovinianism Jovinian denied the special value of consecrated virginity and questioned traditional Christian asceticism.
Siricius supported the condemnation of these teachings.
Priscillianism
Priscillian promoted a mixture of Christian ideas with Gnostic and dualistic influences.
Although Siricius opposed the heresy, he also rejected using capital punishment to settle theological disputes – a significant witness to the Church’s preference for spiritual rather than civil remedies in matters of faith.
Relations with St. Ambrose
Siricius enjoyed close cooperation with St. Ambrose of Milan, one of the greatest bishops of the fourth century.
Together they defended: Nicene orthodoxy, episcopal authority, Church discipline.
This partnership strengthened Catholic unity throughout the Western Empire.

Legacy
St. Siricius transformed the practical administration of the Catholic Church. While earlier popes defended doctrine and settled controversies, Siricius demonstrated how the Bishop of Rome could provide authoritative guidance for the universal Church through written decrees.
His decretals became the foundation of later papal legislation and significantly influenced the development of canon law. At the same time, his defense of orthodoxy and support for clerical discipline strengthened the Church during an era of remarkable growth.
Siricius reminds Catholics that the papacy is not only a guardian of doctrine but also a servant of ecclesial order, ensuring that the universal Church remains united in faith, worship, and discipline.
Did You Know?
The official letters of Pope St. Siricius are often compared to the modern Code of Canon Law. Before his pontificate, popes certainly wrote letters to bishops, but Siricius was the first whose surviving responses clearly functioned as binding legal directives for the wider Church. Because of this, historians frequently call him the father of the papal decretal, an important milestone in the development of Catholic canon law.
Why St. Siricius Matters
St. Siricius helped define how the papacy would govern the universal Church for centuries to come. His official decretals demonstrated that the Bishop of Rome was not merely an honored bishop but a pastor with responsibility for the whole Church. By strengthening ecclesiastical discipline, promoting unity among bishops, and answering questions from across Christendom with authoritative guidance, Siricius laid the groundwork for the later development of canon law and papal governance. His pontificate reminds Catholics that unity in the Church requires both sound doctrine and faithful administration.

The Birth of Papal Canon Law
Before Pope St. Siricius, bishops frequently wrote to Rome for advice. Under Siricius, those responses took on a new level of authority. His decretals became binding norms for bishops throughout the Church and were copied into the earliest collections of canon law. This marked a significant step in the development of the papacy’s universal pastoral office. The system of papal legislation that governs the Catholic Church today – from medieval canon law to the modern Code of Canon Law – can trace one of its earliest and most influential milestones back to Pope St. Siricius.
