By true repentance with tears, prayer and good works the most defiled soul can be completely cleansed and changed. Therefore be careful that you do not maliciously mention the sins of a repentant sinner but offer thanksgiving to God and be astonished how from darkness, light is made and from slime, pure water.
The Egyptian Pharaoh Amasis was of lowly birth and when he became king, men respected him very little, remembering his origin. In order to outwit the people and to gain their respect, he took a metal basin in which, according to custom, the feet of the visitors to the palace were washed. He ordered the basin to be melted down and from it to make a likeness of a certain idol. The pharaoh then placed this idol on the street. Seeing this idol, the people began to worship it and to render it divine honor. Then the pharaoh revealed what this idol was made of. The people then understood that, by this, the pharaoh wanted to show that they need not think anymore about what he once was but what he is now. Then the people began to render the pharaoh the respect due to royalty.
One needs to distinguish a sinner from a penitent. If you have taken upon yourself the role to rebuke the sinner, guard yourself well, that you do not rebuke the penitent also. How dear the repentant sinner is to God; call to mind the Parable of the Prodigal Son. Therefore, let it be very dear for you, he who has become dear to God.
At one time it happened that a monk succumbed to sin for which he was banished from the monastery. This monk went to St. Anthony, confessed his sin, repented and remained with Anthony for a period of time. Then Anthony sent him back again to the monastery but they did not receive him and, again, they banished him. Again, the penitent came to Anthony. Again, Anthony sent him back to the monastery with a message to the fathers of the monastery: "One boat experienced shipwreck and lost its cargo; with great difficulty did that boat arrive in the harbor and you wish to drown even that which was saved from drowning!" Hearing this wise message, the fathers received with joy the penitent brother into the monastery.
