Bonhoeffer

Anybody who has once been horrified by the dreadfulness of his own sin that nailed Jesus to the Cross will no longer be horrified by even the rankest sins of a brother. Looking at the Cross of Jesus, he knows the human heart. He knows how utterly lost it is in sin and weakness, how it goes astray in the ways of sin, and he also knows that it is accepted in grace and mercy. Only the brother under the Cross can hear a confession.
