Mission and Monastic Foundations
Cedd's missionary work among the East Saxons transformed that kingdom, establishing a network of churches and religious communities in a region that had previously reverted to paganism after an earlier Christian mission had faltered. His establishment of monasteries at Bradwell-on-Sea and East Tilbury — communities that drew on the Lindisfarne tradition of Irish-influenced monastic Christianity — gave the East Saxons lasting institutional anchors for the faith.
Lastingham was intended from its founding as a place of intense prayer and ascetic formation. The requirement that the site be cleansed through Lenten fasting before construction reflects the seriousness with which Cedd approached monastic foundation. The monastery later sheltered other members of his family, and after his death his brother Chad governed it briefly before being called to the episcopate.
