Your past and present torments and sufferings are poured down upon you to test your faith and 'steel' it; they also work to curb your lusts and passions. Humble yourself. God gives help to the humble. Judgment of others, insistence on their shortcomings, can only increase the bitterness of your sorrow. Choose the better part.
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.
If something pushes you to criticism about some business or other of a brother or of a monastery, you, rather, try to pray about the matter, without passing it under judgment of your reason.
Do not judge one another, for you transgress the evangelical law, and 'every transgression and disobedience received a just retribution' (Heb. 2:2). 'Who are you to pass judgment on the servant of another?' (Rom. 14:4). Do you not know that the one who passes judgment goes astray through pride, and that everyone who exalts himself will be humbled (Luke 14:11) by the Lord, when temptation seizes him?
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.'
Keep your mind from malicious thoughts of your neighbors, knowing that such thoughts are hurled by diabolical power, to keep your mind from your own sins and from seeking.
My children, avoid criticism -- a very great sin. God is grieved whenever we criticize and loathe people. Let us concern ourselves only with our own faults -- for these let us feel pain; let us criticize ourselves and then we will find mercy and grace from God.
Then we say: 'Forgive us our trespasses as we forgive those who trespass against us.' Brothers, praying thus, we should very much fear lest the Lord reply to these words of our prayer: 'The judgments you give are the judgments you will get, and the amount you measure out is the amount you will be given.' And you who ask this, see whether you did to no one what you did not want done to you. Therefore before we hear these words of the Lord, brethren, let us first examine our hearts as to whether we are with justice asking of the Lord what we have not denied to those asking us. We ask that our trespasses be forgiven us. God hears and He wants to forgive us, but only if we first pardon those who ask us to do likewise.
Do not allow human respect to get in your way when you hear someone slandering his neighbor. Instead, say to him, 'Brother, stop it! I do worse things every day, so how can I criticize him?' You accomplish two things when you say this. You heal yourself and you heal your neighbor with one bandage.
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.'
A brother who shared a lodging with other brothers asked Abba Bessarion, 'What should I do?' The old man replied, 'Keep silence and do not compare yourself with others.'
Do not condemn today as base and wicked the man whom yesterday you praised as good and virtuous, changing love to hatred, because he has criticized you, but even though you are still full of resentment, commend him as before, and you will soon recover your same saving love.
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.
It was said of Abba Arsenius that once when he was ill at Scetis, the priest came to take him to church and put him on a bed with a small pillow under his head. Now behold, and old man who was coming to see him, saw him lying on a bed with a little pillow under his head and he was shocked and said, 'Is this really Abba Arsenius, this man lying down like this?' Then the priest took him aside and said to him, 'In the village where you lived, what was your trade?' 'I was a shepherd,' he replied. 'And how did you live?' 'I had a very hard life.' Then the priest said to him, 'And how do you live in your cell now?' The other replied, 'I am more comfortable.' Then the priest said to him, 'Do you see this Abba Arsenius? When he was in the world he was the guardian of the emperor, surrounded by thousands of slaves with golden girdles, all wearing collars of gold and garments of silk. Beneath him were spread rich coverings. While you were in the world as a shepherd you did not enjoy even the comforts you now have, but he no longer enjoys the delicate life he led in the world. So you are comforted while he is afflicted.' At these words, the old man was filled with compunction and prostrated himself saying, 'Father, forgive me, for I have sinned. Truly the way this man follows is the way of truth, for it leads to humility, while mine leads to comfort.' So the old man withdrew, edified.
