Origen
Catena Aurea · Lukasevangelium 2
And Joseph and his mother marvelled at those things which were spoken of him. And Simeon blessed them, and said unto Mary his mother, Behold, this child is set for the fall and rising again of many in Israel; and for a sign which shall be spoken against; (Yea, a sword shall pierce through thy own soul also,) that the thoughts of many hearts may be revealed.
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.
