This reversal of thoughts is the strongest means, not only for repelling accidental critical thoughts, but also for completely freeing yourself of this vice…
When we see sinners we must always weep for ourselves first over their failure. Perhaps we have fallen in the same way; or we can fall, if we haven't yet. And if the judgment of the teaching office must always eradicate vices by the power of discipline, we must nevertheless make careful distinctions: we should be uncompromising about vice, but compassionate to human nature. If a sinner has to be punished, a neighbor has to be supported. When he has nullified what he has done by his repentance, our neighbor is no longer a sinner. With the righteousness of God he turns against himself, and what the divine righteousness reproves he punishes in himself.
Those who want to be saved scrutinize not the shortcomings of their neighbor but always their own and they set about eliminating them. Such was the man who saw his brother doing wrong and groaned, `Woe is me; him today-me tomorrow!' You see his caution? You see the preparedness of his mind? How he swiftly foresaw how to avoid judging his brother? When he said `me tomorrow' he aroused his fear of sinning, and by this he increased his caution about avoiding those sins which he was likely to commit, and so he escaped judging his neighbor; and he did not stop at this, but put himself below his brother, saying, `He has repented for his sin but I do not always repent. I am never first to ask for forgiveness and I am never completely converted.'
Let him judge of another’s sin who has not on his conscience that which condemns himself. Let him judge who does not himself do what he judges must be punished in another; lest while judging the other he passes sentence upon himself. Let him give judgment on another’s sin who is not led to deliver it by any hate, by dislike, or foolish levity.
We should look upon each believer alike, and suppose that Christ abides in each; we must have such loving disposition towards him as to be ready to lay down our life for him. We should never think or say that someone is evil, but, as is said, should see everyone as good. If you see someone attacked by passions, hate not the brother but the passions attacking him. And when you see someone succumbing to the tyranny of lusts and bad habits, have a still greater compassion for him, lest you suffer a similar temptation - since you are changeable and under the influence of changeable matter.
Practice self-observation. And if you want to benefit yourself and your fellow men, look at your own faults and not those of others. The Lord tells us: 'Judge not, that ye be not judged,' condemn not that ye be not condemned. And the Apostle Paul says: 'Who art thou that judgest another man's servant?'
Abba Or used to say this, 'Do not speak in your heart against your brother like this: 'I am a man of more sober and austere life than he is,' but put yourself in subjection to the grace of Christ, in the spirit of poverty and genuine charity, or you will be overcome by the spirit of vainglory and lose all you have gained. For it is written in the Scriptures: 'Let him who stands take heed lest he fall.' (I Corinthians 10:12) Let your salvation be founded in the Lord.'
Did you see that brother who was negligent and lazy, who did not go down to the all-night vigils and did not do his duties, whom the brothers knew and held to be a negligent brother? When, therefore, he became sick and the hour of his death drew near, the brothers gathered to hear something beneficial, or to comfort him, or in case he wanted to say something to them, but they saw him rejoicing, cheerful. One brother was scandalized and said, But what do we see in you, brother? We see you rejoicing, while you approach death? But our thought says to us that you were not a violent man and how do you have this courage and this rejoicing face? On what do you base this thing? Yes, brothers, he said, really I was a negligent person and I did not fulfill my duties. But I achieved one good thing, by the grace of God -- not to criticize any brother and not to scandalize anyone; and never did I allow my heart to have something against my brother of the monastery when the sun set. And inasmuch as I did not judge my brother, I believe that God will not judge me, even me, for He said, Judge not, that you not be judged (Mt. 7:1); and as long as I did not judge, I will not be judged. The brothers marveled and said, Brother, very easily you found the way of salvation. And the brother died with much joy.
The Lord’s most important commandments are 'Judge not, and ye shall not be judged; condemn not, and ye shall not be condemned; forgive, and ye shall be forgiven.' Moreover, those desirous of salvation should always keep in mind the words of St. Peter Damascene, that creation takes place between fear and hope.
Wherefore a man can know nothing about the judgments of God. He alone is the One Who takes account of all and is able to judge the hearts of each one of us, as He alone is our Master. Truly it happens that a man may do a certain thing (which seems to be wrong) out of simplicity, and there may be something about it which makes more amends to God than your whole life; how are you going to sit in judgment and constrict your own soul? And should it happen that he has fallen away, how do you know how much and how well he fought, how much blood he sweated before he did it? Perhaps so little fault can be found in him that God can look on his action as if it were just, for God looks on his labor and all the struggle he had before he did it, and has pity on him. And you know this, and what God has spared him for, are you going to condemn him for, and ruin your own soul? And how do you know what tears he has shed about it before God? You may well know about the sin, but you do not know about the repentance.
Do not judge and do not belittle anyone, because from this the heart grows faint and the mind is blinded, and from this, negligence appears and unfeelingness of heart is born. Keep ceaseless vigil, learning in the law of God, for through this the heart is warmed by heavenly fire, as is said: 'In my meditation a fire was kindled.'
St. Paul ... says, ... 'By judging another you condemn yourself' (Rom. 2:1). But men have given up weeping for their own sins and have taken judgment away from the Son. They themselves judge and condemn one another as if they were sinless.
Fire and water do not mix, neither can you mix judgment of others with the desire to repent. If a man commits a sin before you at the very moment of his death, pass no judgment, because the judgment of God is hidden from men. It has happened that men have sinned greatly in the open but have done greater deeds in secret, so that those who would disparage them have been fooled, with smoke instead of sunlight in their eyes.
Even if a person’s sin is not only obvious, but very grievous and comes from a hardened and unrepentant heart, do not condemn him, but raise your eyes to the wondrous and incomprehensible judgments of God; then you will see that many people, formerly full of iniquity, later repented and reached a high degree of sanctity, and that, on the other hand, others, who were on a high level of perfection, fell into a deep abyss. Take care, lest you also suffer this calamity through judging others.
Abba Ammonas came one day to eat in a place where there was a monk of evil repute. Now it happened that a woman came and entered the cell of the brother of evil reputation. The dwellers in that place, having learnt this, were troubled and gathered together to chase the brother from his cell. Knowing that Bishop Ammonas was in the place, they asked him to join them. When the brother in question learnt this, he hid the woman in a large cask. The crowd of monks came to the place. Now Abba Ammonas saw the position clearly but for the sake of God he kept the secret; he entered, seated himself on the cask and commanded the cell to be searched. Then when the monks had searched everywhere without finding the woman, Abba Ammonas said, 'What is this? May God forgive you!' After praying, he made everyone go out, then taking the brother by the hand he said, 'Brother, be on your guard.' With these words, he withdrew.
He who knows himself pays no heed to the sins of others, but looks at his own and is always repenting over them; he reflects concerning himself, and condemns himself, and does not interfere in anything apart from his own position.
