There will always be a cross somewhere in the midst of the Christian solution to evil, the cross of the pain involved in not returning blow for blow; a cross of the natural, human bitterness felt in the experiencing of hatred and returning love in its place, of receiving evil and doing good; a cross reflected in the near impossibility of counting oneself blessed in the midst of persecution, or of hungering and thirsting for justice, or in being merciful and peacemakers in a world which understands neither. Between us and fulfillment, between us and everlasting justice, between us and salvation of the suffering world, there will always stand the paradox of the cross, a cross not for others, but for us.
