Rats and roaches live by competition under the laws of supply and demand; it is the privilege of human beings to live under the laws of justice and mercy.
The Christian gospel is a summons to peace, calling for justice beyond anger, mercy beyond justice, forgiveness beyond mercy, love beyond forgiveness.
Violence breeds violence. Acts of violence committed in "justice" or in affirmation of "rights" or in defense of "peace" do not end violence. They prepare and justify its continuation.
These are people who are capable of devotion, public devotion, to justice. They meant what they said and every day that passes, they mean it more.
