An influx of heathenism occurred on two later occasions: in the ninth century there was an invasion by the heathen Danes under Guthrum; and in the eleventh century the heathen king Cnut led his hordes to victory. As in the case of the Saxon kings of the seventh century, Guthrum and Cnut were converted and the tribes followed their leaders' example, professed Christianity, and were baptized.
But it cannot be imagined that these wholesale conversions were more than nominal in most cases, though the king's religion was outwardly the tribe's religion. If, as happened among the East Saxons, the king forsook his old gods, returned to them again, and finally forsook them altogether, the tribe followed his lead, and, in public at least, worshipped Christ, Odin, or any other deity whom the king favoured for the moment; but there can be hardly any doubt that in private the mass of the people adhered to the old religion to which they were accustomed. This tribal conversion is clearly marked when a heathen king married a Christian queen, or vice versa; and it must also be noted that a king never changed his religion without careful consultation with his chief men.[3] An example of the two religions existing side by side is found in the account of Redwald, King of the East Saxons, who 'in the same temple had an altar to sacrifice to Christ, and another small one to offer victims to devils'.[4]
The continuity of the ancient religion is proved by the references to it in the classical authors, the ecclesiastical laws, and other legal and historical records.
1st cent. Strabo, 63 b.c.-a.d. 23.
'In an island close to Britain, Demeter and Persephone are venerated with rites similar to the orgies of Samothrace.'[5]
4th cent. Dionysius says that in islands near Jersey and Guernsey the rites of Bacchus were performed by the women, crowned with leaves; they danced and made an even greater shouting than the Thracians.[6]
7th cent. Theodore, Archbishop of Canterbury, 668-690.
The Liber Poenitentialis[7] of Theodore contains the earliest ecclesiastical laws of England. It consists of a list of offences and the penance due for each offence; one whole section is occupied with details of the ancient religion and of its rites. Such are:
Sacrifice to devils.
Eating and drinking in a heathen temple, (a) in ignorance, (b) after being told by the [Christian] priest that it is sacrilege and the table of devils, (c) as a cult of idols and in honour of idols.
