A brother asked Abba Poemen, saying, “What is the repentance of sins?” And he said unto him, “The repentance of sins consists in a man not committing the sin again from the moment wherein he repents of it; and on accout of this the righteous were called ‘spotless,’ and because they had forsaken their sins, and had cleansed themselves from them.” – Paradisus Patrum
