"This we have always known, but today we see it in a really terrifying
way, that the greatest persecution of the church does not come from
the enemies outside but is born from the sin in the church," he added.
"The church has a profound need to relearn penance, to accept
purification, to learn on the one hand forgiveness but also the
necessity of justice. And forgiveness does not substitute justice."
The rest of the Catholic hierarchy needs to follow Benedict's example.
