Saint Eustathius of Antioch: The Defender of the Nicene Creed
Saint Eustathius of Antioch, often referred to as "the Great," was a pivotal figure in the 4th-century Christian church. As the Patriarch of Antioch, he stood at the center of the theological storms that shaped the foundational doctrines of Christianity. His life was marked by a fierce commitment to the Nicene faith, a bitter rivalry with the Eusebians, and a legacy that persisted long after his exile.
Born in Side, within the Roman province of Pamphylia, Eustathius rose through the ecclesiastical ranks to become the Bishop of Beroea around 320 AD. Shortly before the historic Council of Nicaea in 325 AD, he ascended to the position of Patriarch of Antioch, placing him in a position of significant influence during one of the most critical assemblies in church history.

The Council of Nicaea and the Fight Against Arianism
At the Council of Nicaea, Eustathius distinguished himself as a vigorous opponent of Arianism (the belief that Jesus Christ was a created being and not co-eternal with God the Father). He joined forces with Alexander and Marcellus to ensure the victory of the pro-Nicene position.
Their collaboration was instrumental in the drafting of the Nicene Creed. Specifically, they championed the term homoousios (meaning "of the same substance"), which asserted that the Son is of the same essence as the Father. While this term became a cornerstone of orthodox faith, it also made Eustathius a target for his opponents.
The Conflict of Homoousios and Exile
Following the council, the struggle shifted from Arius himself to the interpretation of the term homoousios. The Eusebians, led by Eusebius of Caesarea, argued that this term implied Sabellianism—a heresy suggesting that the Father and the Son are not distinct persons but merely different modes of a single entity.
Eustathius countered by accusing Eusebius of Caesarea of deviating from the very doctrines ratified at Nicaea. This polemic battle eventually turned against him. In 330 AD, a synod convened in Antioch deposed Eustathius on charges of Sabellianism, a decision subsequently confirmed by Emperor Constantine the Great.
Despite the support of his followers in Antioch, who were prepared to take up arms in his defense, Eustathius urged them to remain peaceful. He humbly accepted his banishment and traveled to Trajanopolis in Thrace, accompanied by many of his clergy. He remained there until his death, which occurred approximately in 337 AD (though some sources suggest as late as 370 AD).
The Meletian Schism
The influence of Eustathius extended beyond his lifetime. In 360 AD, when Meletius became the Bishop of Antioch, the "Eustathians" (the old Catholic party) refused to recognize him. This intransigence led to the Meletian Schism, a divide that troubled both the Eastern and Western churches until the early 5th century.
The schism highlighted deep tensions between the East and West. While Western bishops like Damasus supported Paulinus I (the Eustathian successor), prominent Eastern figures such as Basil the Great sided with Meletius. The conflict centered on the precise definition of the Holy Trinity and the fear of being labeled either an Arian or a Sabellian.

Frequently Asked Questions
Why was Saint Eustathius deposed as Patriarch?
He was deposed by a synod in Antioch in 330 AD after being accused of Sabellianism, a theological error regarding the distinct persons of the Trinity. This was largely driven by his conflicts with the Eusebian faction.
What was the significance of the term homoousios in his life?
The term homoousios ("of the same substance") was the central point of contention. Eustathius fought for its inclusion in the Nicene Creed to refute Arianism, but his opponents used the term to accuse him of Sabellianism.
What is the Meletian Schism?
The Meletian Schism was a long-standing division in the church at Antioch between the followers of Meletius and the "Eustathians" (supporters of Eustathius's legacy), lasting until the second decade of the 5th century.
What writings are attributed to Saint Eustathius?
The only complete work attributed to him is De Engastrimytho contra Origenem. While a Commentary on the Hexameron is found in some manuscripts, it is considered too late to be authentic.
