244 When conflicts are not resolved but kept hidden or buried in the past, silence can lead to complicity in grave misdeeds and sins. Authentic reconciliation does not flee from conflict, but is achieved in conflict, resolving it through dialogue and open, honest and patient negotiation. Conflict between different groups “if it abstains from enmities and mutual hatred, gradually changes into an honest discussion of differences founded on a desire for justice”.
