Episcopalians Against Gun Violence released the following statement today:
On Tuesday, October 3 at 9 am Pacific, churches across the Episcopal Diocese of Nevada will toll their bells in mourning for the victims of the shooting in Las Vegas. Bishops United Against Gun Violence invites congregations across the country to toll their own bells in solidarity at the same time: 9 am Pacific/10 am Mountain/11 am Central/Noon Eastern. The number of times the bells are rung will be based on the number of dead as reported at that time.
Their page will be updated Tuesday morning with more information.
