"In our thoughts and at confession we must not dwell on sins that have been already confessed. Because of our contrition Jesus has forgiven them at the tribunal of penance. There He faced us and our miseries like a creditor in front of a debtor. With a gesture of infinite generosity He tore up and destroyed the bills we could certainly not have paid without the help of his divine clemency. To go back to these sins, to bring them up again just to have them forgiven again, because of doubt that they were really and abundantly remitted, would this not be considered a lack of trust in the goodness which He proved by his tearing up every document of debt contracted through sin?…. Dwell on them, if it is a source of comfort for your soul. By all means think of the offenses against justice, wisdom and the infinite mercy of God, but only for the purpose of weeping redemptive tears of repentance and love."   St.  Pio  of Pietrelcina (G. Festa, Tra i misteri della scienza e le luci della fede, 169)
