The Mission to the English
The mission was conceived and directed by Pope Gregory the Great, who took a personal interest in the evangelization of the Anglo-Saxons and remained in correspondence with Augustine, sending instruction and further laborers. Gregory reported that more than ten thousand Christians had been baptized, the tradition placing a great baptism at Christmas. The seed planted in Kent spread outward, and in 604 Augustine consecrated Mellitus as bishop for London and Justus as bishop for Rochester, extending the church's structure beyond Canterbury.
Augustine also sought to bring the existing British (Welsh) Christians into common order and under his oversight, but the meeting with their bishops did not succeed; the tradition relates that they declined to acknowledge his authority. This left the older British church and the new mission from Rome as distinct bodies, a division that would be addressed by later generations.
