Do not regard the feelings of a person who speaks to you about his neighbor disparagingly, but rather say to him: 'Stop, brother! I fall into graver sins every day, so how can I criticize him?' In this way you will achieve two things: you will heal yourself and your neighbor with one plaster. This is one of the shortest ways to the forgiveness of sins; I mean, not to judge. 'Judge not, and ye shall not be judged,' (Luke 6:37).
He who refuses to accept a criticism, just or not, renounces his own salvation, while he who accepts it, hard or not though it may be, will soon have his sins forgiven.
Anger is by nature designed for waging war with the demons and for struggling with every kind of sinful pleasure. Therefore angels, arousing spiritual pleasure in us and giving us to taste its blessedness, incline us to direct our anger against the demons. But the demons, enticing us towards worldly lusts, make us use anger to fight with men, which is against nature, so that the mind, thus stupefied and darkened, should become a traitor to virtues.
A man who falls into sin is different from the way he was created. He is different, because he changes by his own actions the way he was meant to be. Man renounces himself when he becomes a different person through repentance. He leaves a corrupted man, which he had become through sin, and becomes such as he once was created, through mercy.
Some, for the sake of forgiveness, give themselves up to labors and struggles, but a man who is forgetful of wrongs excels them. If you forgive quickly, then you will be generously forgiven.
