Origen — as excerpted in the Catena Aurea on Luke 2:33-35

“But the evil thoughts of men were revealed, that He Who died for us might slay them; for while they were hidden, it was impossible to utterly destroy them. Hence also when we have sinned we ought to say, Mine iniquity have I not hid. (Ps. 32:5.) For if we make known our sins not only to God, but to whoever can heal our wounds, our sins will be blotted out.”
