In confession occurs the breakthrough of the Cross. The root of all sin is pride, superbia. I want to be my own law, I have a right to my self, my hatred and my desires, my life and my death. The mind and flesh of man are set on fire by pride; for it is precisely in his wickedness that man wants to be as God. Confession in the presence of a brother is the profoundest kind of humiliation. It hurts, it cuts a man down, it is a dreadful blow to pride...In the deep mental and physical pain of humiliation before a brother - which means, before God - we experience the Cross of Jesus as our rescue and salvation. The old man dies, but it is God who has conquered him. Now we share in the resurrection of Christ and eternal life.
