Theophilus of Alexandria (Greek: ÃÂõÃÂÃÂùûÿÃÂ; died 15 October 412) was the 23rd Pope of Alexandria and Patriarch of the See of Saint Mark from 385 to 412. He is remembered as a pivotal figure in late antique Christianity, known for his assertive role in suppressing paganism and managing ecclesiastical disputes that shaped the doctrinal course of the early Church.
Theophilus rose to the patriarchate during a time of significant transformation in the Roman Empire. Christianity had recently gained imperial support through the policies of Constantine and Theodosius I, displacing long-dominant pagan cults. Alexandria, a center of learning and philosophical traditions, became a focal point of religious and political tensions.
Little is known about TheophilusâÂÂs early life, though he was likely born in Egypt in the mid-4th century. He succeeded Pope Timothy I as Patriarch of Alexandria in 385 AD. His nephew, Cyril of Alexandria, whom he mentored, later succeeded him in the same office.
In 391 AD, following a series of imperial edicts issued by Emperor Theodosius I that banned pagan worship and closed temples across the empire, Patriarch Theophilus I of Alexandria led efforts to repurpose or dismantle pagan religious structures in Alexandria. According to the church historian Socrates Scholasticus, Theophilus publicly mocked pagan artifacts, an act that provoked violent clashes between pagan and Christian factions in the city.
One of the most significant events during this period was the destruction of the Serapeum of Alexandria, one of the most prominent temples in the ancient city. While Christian sources described the incident as a victorious moment in the struggle against idolatry, modern scholars note that the event reflected broader political, religious, and social tensions in late Roman Alexandria. Some argue that the temple's destruction was part of a wider campaign to consolidate Christian authority and imperial control.
Though Theophilus initially supported the allegorical theology of Origen, he changed his position in 399 AD, aligning instead with âÂÂAnthropomorphiteâ monks who interpreted divine imagery literally. At a synod in Alexandria, he condemned Origen's writings and expelled Origenist monks. This included the influential group known as the Four Tall Brothers, intellectuals who later sought refuge under John Chrysostom in Constantinople.
In 403, Theophilus presided over the Synod of the Oak in Constantinople, orchestrating the deposition of John Chrysostom, then Archbishop of Constantinople. Theophilus accused him of insubordination and heresy, partly due to Chrysostom's sheltering of the exiled Origenists.
Theophilus was a prolific author, though most of his writings survive only in fragments or translations. His surviving corpus includes:
Some of his prayers were translated into Geýez, the liturgical language of the Ethiopian Orthodox Tewahedo Church, signifying his lasting influence beyond Egypt.
Theophilus died on 15 October 412 and was buried in Alexandria. He is venerated as a saint in the Coptic Orthodox Church, the Eastern Orthodox Church, and the Syriac Orthodox Church. His feast day is celebrated on 18 Paopi in the Coptic calendar, corresponding to 28 October on the Gregorian calendar.
