In his book Resurrection: Interpreting the Easter Gospel Rowan Williams makes the following observation about churches as communities of the resurrection:

The church’s work of judgment, its critical role in the world, is a nonsense (and worse) if criticism is not built into its own life and structures.  Only a penitent church can manifest forgiveness–a tautology, perhaps, but worth saying.  A merely critical Church can reproduce in horrifying forms precisely those oppressive and exclusive relations which it exists to judge.  it will pass sentence upon those beyond its boundaries, and so will be concerned about those boundaries and their exact definition. It will, explicitly or implicitly, see ‘belonging to the Church’ as a matter of fulfilling conditions of membership; so that it possesses criteria by which some believers can be cut off when necessary from its life. It thus encourages that attitude between believers or groups of believers which is almost preternaturally alert to failure and delinquency. I am not speaking simply of certain kinds of Irish Catholicism or Welsh nonconformity (such as have been immortalized by James Joyce or Caradoc Evans); soi-disant ‘ radical’ Christianity is capable of the same level of pharisaism. a former Archbishop of Cape Town has written searchingly of the temptation, in a situation of acute political strain in conflict, to ‘bludgeoned’ the opposition with accusations designed to engender guilt rather than (in the widest sense) conversion, and converted action. The exposed situation of the prophetic or protesting group often seems to require for its security the firm projection of guilt on to the dissident or lukewarm; and any sense of judgment and grace or hope flowing together from the awareness of forgiven-ness and the prophetic group is pretty elusive. (Williams, p 46-47)
