" Sin is the reality of our lives and of this world. Sin is the dark side, the contrary power, the destructive activity in the world. To triumph over sin would mean to build up our lives, the lives of others, of the family, of the community, of the Church, of the world, without ever making a step backward... The triumph over sin would mean that now a single justified desire would ever be frustrated, that not a single sigh would ever be ignored, that not a single tear would ever fall into the dark abyss of despair, and that not a single hope would ever be betrayed.
