This reversal of thoughts is the strongest means, not only for repelling accidental critical thoughts, but also for completely freeing yourself of this vice…
Love sinners, but hate their works, and do not despise them for their faults, lest you be tempted by the same. Remember that you share the earthly nature of Adam and that you are clothed with his infirmity.
When we look down upon any man, because of his color, nationality, or some other shallow thing, we destroy our own souls. Since we are one with all men in Christ, we condemn ourselves when we condemn others. And since the Holy Spirit dwells in all people, when we denigrate anyone for what he is, we blaspheme the Holy Spirit, which indwells him. It is wise for a man, therefore, to avoid anyone who speaks against others because of the color of their skin or because of any other external attribute which God has given them.
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.
A holy elder, seeing with his own eyes a certain brother fall into deep sin, not only did not judge him, but wept and said: 'He fell today; without doubt I will fall tomorrow. But he certainly will repent, whereas for myself, I am not so sure of this.'
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.
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.'
In truth, whatever we may suffer, we suffer it because of our sins. If the saints suffered, they suffered for God's name or to demonstrate their virtue for the benefit of many or to gain greater reward from God. As for us wretches, how can we say this? We sin like this daily and in seeking to satisfy our passion, we abandoned the right path, which the Fathers spoke about, that of self-accusation. Each one of us follows the wrong path, tries on every occasion to put the case against his brother and throw the burden of responsibility upon him. Each one of us is negligent and keeps nothing, but demands that our neighbor keeps the commandments.
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 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.'
Since the enemy watches you constantly, waiting for an opportunity to sow evil in you, be doubly watchful over yourself, lest you fall in the nets spread for you. As soon as he shows you some fault in your neighbor, hasten to repel this thought, lest it take root in you and grow. Cast it out, so that no trace is left in you, and replace it by the thought of the good qualities you know your neighbor to possess, or of those people generally should have. If you still feel the impulse to pass judgment, add to this the truth that you are given no authority for this and that the moment you assume this authority you thereby make yourself worthy of judgment and condemnation, not before powerless men, but before God, the all-powerful Judge of all.
An elderly monk said, 'Always, when you are tempted to criticize, you should put a question mark on the whole situation and not judge. For we do not know what is really going on.'
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.
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?'
