Park Slope’s Trinity Grace Church recently joined S.O.S. in celebrating S.O.S. Week and Nonviolence Worship Weekend. The church’s Crown Heights Missional Community group, which seeks opportunities to serve and engage with other Crown Heights residents, participated in the March to End Gun Violence earlier this month. During Trinity Grace’s June 10 service, James Cernero, the group’s leader, spoke about the work of S.O.S. and led the congregation in a prayer for S.O.S. workers and high-risk youth, as well as peace in the community.
