How a Roman monk turned a pagan kingdom into the heart of English Christianity

In short: In 597, a Benedictine leader arrived on the shores of Kent with a small band of monks. Sent by Pope Gregory the Great, he faced a daunting mission to convert a pagan Anglo-Saxon society. His success transformed Canterbury into the spiritual center of England, a status it holds today.

Augustine, likely of noble background, was leading a monastery dedicated to St. Andrew in Rome when Pope Gregory I selected him for a mission to Britain. The task was unprecedented: to reintroduce Christianity to a land where paganism had taken root following the departure of Roman legions centuries earlier. The mission began with hesitation; after initially turning back due to fears of the journey, Augustine was encouraged by papal letters and eventually landed on the Isle of Thanet in 597.

The mission found a strategic foothold in the Kingdom of Kent, ruled by King Aethelberht. The king’s marriage to Bertha, a Frankish princess who was already a Christian, provided a crucial opening. Aethelberht allowed the missionaries to settle in Canterbury and use the ancient St. Martin’s Church. The impact was rapid; after the king’s own conversion, thousands of his subjects were baptized on Christmas Day in 597. This success prompted the arrival of further support from Rome, including the pallium, a symbol of metropolitan authority, which solidified Augustine’s role as the first archbishop of Canterbury.

Augustine’s efforts to expand the church included establishing episcopal sees in London and Rochester by 604. However, his attempts to unify the newly established Roman-aligned church with the existing Celtic Christian traditions in western Britain were unsuccessful. Despite these tensions, he founded Christ Church and the monastery of SS. Peter and Paul, which became a burial site for early archbishops. By the time of his death in 604 or 605, Augustine had laid the foundation for the primatial see of England, permanently altering the religious landscape of the British Isles.
