"no reconciliation, no forgiveness and no negotiations are possible without repentance. The Biblical teaching on reconciliation and forgiveness makes it quite clear that nobody can be forgiven and reconciled with God unless he or she repents of their sins. Nor are we expected to forgive the unrepentant sinner. When he or she repents we must be willing to forgive seventy times seven times but before that, we are expected to preach repentance to those who sin against us or against anyone. Reconciliation, forgiveness and negotiations will become our Christian duty in South Africa only when the apartheid regime shows signs of genuine repentance."
Challenge to the church: a theological comment on the political crisis in South Africa (The KAIROS document, 25 September 1985), 3.1 (Reconciliation). I have not read this through.
