To be subject to the injustices of the world is part of the human condition. Nobody knew that better than Jesus, and his followers must accept it as part of the cross they are asked to take up. 

But the Church should never particulate in that injustice. Never. We should be fiercely devoted to the truth, however painful and whatever the consequences. That's why those in positions of responsibility should recuse themselves from situations where they might be tempted to act out of self-interest or misguided bias.  

Imperfect as it is, the best place for Cardinal Pell's case is in the courts. All we can do is pray for him, for the victims of child abuse and for the wisdom and integrity of those charged with rendering justice.
