What is the importance of the Saints Cuthbert and Bede in the establishment of the early Christian Church in Britain?

Saint Cuthbert and Saint Bede were two of the earliest monks and eventual saints in the British Isles. Cuthbert, a native of the region, was born and became a Christian not long after the King of Northumbria, a region in Northeast England, became a Christian.
Cuthbert was renowned for his kindness and devotion to scripture and missionary practice. He was no revolutionary figure, not inspiring massive waves of saints but instead living a very humble life. He became the prior of the local monastery and spent his time traveling the countryside, preaching, giving out food and gifts, and serving people. He preached a strict ascetic lifestyle, but his kindness and charity won many over to him. It was his kindness that led to the spread of the Gospel in that region more so than anything else. After he died, many miracles were attributed to him, and his posthumous fame continued to grow until he was beatified.
Bede, who came several years after Cuthbert, was known as one of the most intelligent and well-educated men of his time, and he devoted his life to recording the history of English saints, particularly Cuthbert. This increased his legendary status, and together, his writings, along with Cuthbert's deeds, helped Christianity spread throughout the British Isles.
