When did the first Christian communities appear in Britain?

Christianity's arrival in Britain is linked to the Roman Empire, which controlled the region for several centuries. While it's hard to pinpoint an exact date, evidence suggests that Christian communities began to emerge during the 3rd and 4th centuries AD. This was a time when Christianity was gradually spreading across the Roman Empire, though it wasn't yet the official state religion. Archaeological finds, like mosaics with Christian symbols and early church structures, support this timeline. By the 4th century, there were definitely established Christian communities, and British bishops even attended church councils on the continent. So, while individual Christians might have arrived earlier, the formation of organized Christian communities really took hold in the 3rd and 4th centuries. The other options are incorrect because the evidence points to a later start than the 2nd century, and the 5th and 6th centuries were a period of significant change with the arrival of the Anglo-Saxons, who initially practiced pagan religions.
