Do not lend your ear to the tongue of the slanderer, nor your tongue to the ear of him who likes malicious talk, speaking or listening with enjoyment to words against one's neighbor. Cut yourself off from them, lest you fall away from love of God and find yourself exiled from eternal life.
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.'
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?
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.
Intemperance and attachment to things cause torrents of passions to flood the soil of the heart and deposit there all the mud and filth of thoughts, thus confusing the mind, darkening the heart and weighing down the body. In the heart and the soul they produce negligence, darkness and death and deprive them of the feeling and disposition natural to them.
Never allow yourself boldly to judge your neighbor; judge and condemn no one, ... rather have compassion and pity for him, but let his example be a lesson in humility to you; realizing that you too are extremely weak and as easily moved to sin as dust on the road, say to yourself: 'He fell today, but tomorrow I shall fall.'
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.
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.
When you go to your spiritual father for confession, do not bring yourself as an accuser of other people, saying, 'he said this,' and 'so-and-so said that'. . . but speak about your own doings, so that you may obtain forgiveness.
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?'
Set your sight on heaven and order every step of your life so that it will be a step in that direction. It seems to me that it is all so simple, and yet so all-embracing.
