Ambrose of Milan — as excerpted in the Catena Aurea on Luke 15:17-24

“How merciful! He, though offended, disdains not to hear the name of Father. I have sinned; this is the first confession of sin to the Author of nature, the Ruler of mercy, the Judge of faith. But though God knows all things, He yet waits for the voice of thy confession. For with the mouth confession is made to salvation, since he lightens the load of error, who himself throweth the weight upon himself, and shuts out the hatred of accusation, who anticipates the accuser by confessing. In vain would you hide from Him whom nothing escapes; and you may safely discover what you know to be already known. Confess the rather that Christ may intercede for thee, the Church plead for thee, the people weep over thee: nor fear that thou wilt not obtain; thy Advocate promises pardon, thy Patron favour, thy Deliverer promises thee the reconciliation of thy Father’s affection. But he adds, Against heaven and before thee.”
