As of Late, I've been concerned with the Jesuit teaching of the Charitable Interpretation- and how it often seems to inspire unilateral forgiveness- that is, Mercy GRANTED without repentance. This seems to me to be against the Gospel of Luke:
Tonight I watched a Father Brown murder mystery, _The Deadly Seal_ on PBS. I don't remember this one from the GK Chesterton Father Brown books I've read. It includes two confessions by a murderer, to hide a murder. In the second confession- Father Brown says that even God's forgiveness requires repentance- and he urges the murderer in a third confession to widen the confession to the police. The first two times repentance was claimed, it was false. The third time, it was true. In no way did Father Brown *refuse* the forgiveness of God to the murderer- he only told her what she needed to do to attain it.
Even at the order of the Bishop- he never breaks the seal of the confessional.
I think this is the proper way to approach sin. Don't be wavering in being outspoken that the sin is wrong. Keep forgiving every time the person repents. But repentance IS necessary. For without repentance- without true repentance- it's only an act. Just like in this episode- where the actress did it.
