The small, quiet town in Fairfield County is a world away from the streets of Dorchester, but the two communities are, in a sense, linked: Both mourn the innocent children they have lost to gun violence. Bishop M. Thomas Shaw, leader of the Episcopal Diocese of Massachusetts, saw that connection when he and his staff were putting together a day of workshops aimed at helping church members — including many small-town dwellers and suburbanites — find ways to help end violence, part of the B-PEACE for Jorge campaign.
