Chapter IV (1)
Medieval The Venerable Bede Englishlucius, king of britain, writing to pope eleutherus, desires to be made a christian
In the year of our Lord’s incarnation 156, Marcus Antoninus Verus, the fourteenth from Augustus, was made emperor, together with his brother, Aurelius Commodus. In their time, whilst Eleutherus, a holy man, presided over the Roman church, Lucius, king of the Britons, sent a letter to him, entreating that by his command he might be made a Christian. He soon obtained his pious request, and the Britons preserved the faith, which they had received, uncorrupted and entire, in peace and tranquillity until the time of the Emperor Diocletian.
