During Laurence's reign, Ethelbert died (616) and his son Eadbald returned to the old faiths and many prominent missionaries fled to Gaul. But Laurence managed to reconvert him. The tale is that Laurence had been prepared to give up when he was visited by St. Peter in a vision, who chastised him and whipped him. The marks of the whipping remained and the display of them to Eadbald effected his conversion.
On his death he was buried in St. Peter's Abbey church, later renamed St. Augustine's. His festival is on February 3.
