As you most likely already read, Episcopal Church Presiding Bishop Katharine Jefferts Schori called for prayer following the explosions in Boston, MA, and offers the following prayer:

Gracious God, you walk with us through the valley of the shadow of death.  We pray that the suffering and terrorized be surrounded by the incarnate presence of the crucified and risen one.  May every human being be reminded of the precious gift of life you entered to share with us.  May our hearts be pierced with compassion for those who suffer, and for those who have inflicted this violence, for your love is the only healing balm we know. May the dead be received into your enfolding arms, and may your friends show the grieving they are not alone as they walk this vale of tears.  All this we pray in the name of the one who walked the road to Calvary.

I write with such sadness to remind you of the all-too-recent post containing resources for families needing to address this senseless act of violence. You will find the post here.
