[10] After the Roman legions withdrew from Britannia in 410 the natives of Great Britain were left to defend themselves, and non-Christian Angles, Saxons, and Jutes—generally referred to collectively as Anglo-Saxons—settled the southern parts of the island.
[8][11] Evidence for the continued existence of Christianity in eastern Britain at this time includes the survival of the cult of Saint Alban and the occurrence of eccles—from the Latin for church—in place names.
"[18] Most of the information available on the Gregorian mission comes from the medieval writer Bede, especially his Historia ecclesiastica gentis Anglorum, or Ecclesiastical History of the English People.
The early Life of Gregory is generally believed to have been based on oral traditions brought to northern England from either Canterbury or Rome, and was completed at Whitby Abbey between 704 and 714.
Although he found some native British clergy worthy of praise he nevertheless condemned them for their failure to convert the invaders and for their resistance to Roman ecclesiastical authority.
[28] Other sources of information include Bede's chronologies, the set of laws issued by Æthelberht in Kent, and the Anglo-Saxon Chronicle, which was compiled in the late 9th century.
[40] In 595 Gregory wrote to one of the papal estate managers in southern Gaul, asking that he buy English slave boys so that they might be educated in monasteries.
[49] There is some evidence, including Gregory's letters to Frankish kings in support of the mission, that some of the Franks felt they had a claim to overlordship over some of the southern British kingdoms at this time.
[54] Another reason for the pause may have been the receipt of news of the death of King Childebert II, who had been expected to help the missionaries; Augustine may have returned to Rome to secure new instructions and letters of introduction, as well as to update Gregory on the new political situation in Gaul.
Augustine then returned to the rest of the missionaries, with new instructions, probably including orders to seek consecration as a bishop on the Continent if the conditions in Kent warranted it.
The historian R. A. Markus feels that this was due to a strong pagan presence in the kingdom that forced the king to rely on indirect means including royal patronage and friendship to secure conversions.
[67] Bede records the letter and Gregory's replies in chapter 27 of his Historia ecclesiastica gentis Anglorum, this section of the History is usually known as the Libellus responsionum.
Other topics were relations between the churches of Britain and Gaul, childbirth and baptism, and when it was lawful for people to receive communion and for a priest to celebrate mass.
Markus argues that the pope, after thinking further about the circumstances of the mission in Britain, then sent a follow-up letter, the Epistolae ad Mellitum, to Mellitus, then en route to Canterbury, which contained new instructions.
[83] Later, Aldhelm, the abbot of Malmesbury, writing in the later part of the 7th century, claimed that the native clerks would not eat with the missionaries, nor would they perform Christian ceremonies with them.
[88] Most of the information on the Gregorian mission comes from Bede's narrative, and this reliance on one source necessarily leaves the picture of native missionary efforts skewed.
[94] The historian N. J. Higham suggests that a synod, or ecclesiastical conference to discuss church affairs and rules, was held at London during the early years of the mission, possibly shortly after 603.
[97] The Frankish kings in Gaul were increasingly involved in internal power struggles, leaving Æthelbertht free to continue to promote Christianity within his own lands.
Although Bede does not give details of any political factors surrounding the event, it is likely that by expelling Mellitus the sons were demonstrating their independence from Kent, and repudiating the overlordship that Æthelberht had exercised over the East Saxons.
Bede states that after Æthelberht's death Eadbald refused to be baptised and married his stepmother, an act forbidden by the teachings of the Roman Church.
[108] About the time that Edwin died in 633, a member of the East Anglian royal family, Sigeberht, returned to Britain after his conversion while in exile in Francia.
Instead, they lived more as secular clergy serving a cathedral church, and it appears likely that the sees established at Rochester and London were organised along similar lines.
The historian Henry Mayr-Harting argues that in addition, most of the Gregorian missionaries were concerned with the Roman virtue of gravitas, or personal dignity not given to emotional displays, and this would have limited the colourful stories available about them.
But being converted by an agent of the distant Roman pontiff was not only safer, it allowed the added prestige of accepting baptism from the central source of the Latin Church.
[121] The idea that an archbishop needed a pallium to exercise his archiepiscopal authority derives from the Gregorian mission, which established the custom at Canterbury from where it was spread to the Continent by later Anglo-Saxon missionaries such as Willibrord and Boniface.
[124] The historian R. A. Markus suggests that the Gregorian mission was a turning point in papal missionary strategy, marking the beginnings of a policy of persuasion rather than coercion.
[123] Gregory, in Bede's work, is the driving force behind the Gregorian mission, and Augustine and the other missionaries are portrayed as depending on him for advice and help in their endeavours.
[47] Honorius,[130] Justus,[131] Lawrence,[132] Mellitus,[133] Paulinus,[134] and Peter, were also considered saints,[135] along with Æthelberht, of whom Bede said that he continued to protect his people even after death.
[61] A few objects at Canterbury have traditionally been linked with the mission, including the 6th-century St Augustine Gospels produced in Italy, now held at Cambridge as Corpus Christi College MS 286.
Williams sees the issuing of legal codes as not just laws but also as statements of royal authority, showing that the kings were not just warlords but also lawgivers and capable of securing peace and justice in their kingdoms.
