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.'
Christians should judge no one, neither an open harlot, nor sinners, nor dissolute people, but should look upon all with simplicity of soul and a pure eye. Purity of heart, indeed, consists in seeing sinful and weak men and having compassion for them and being merciful.
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.
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.'
Do not rail against anyone, but rather say ‘God knows each one.’ Do not agree with him who slanders, do not rejoice at his slander and do not hate him who slanders his neighbor. This is what it means not to judge.
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.
No man, wise in his own opinion, because he has studied all the sciences and is learned in external wisdom, will ever penetrate God's mysteries or see them unless he first humbles himself and becomes foolish in his heart, repudiating his self-opinion together with his acquirements of learning. For a man who acts thus and follows with undaunted faith those who are wise in things Divine, is guided by them and with them enters into the city of the living God, and, taught and enlightened by the Holy Spirit, sees and knows things which no one else can see or know. Thus he becomes taught of God.
Keep from prying into other people's affairs, for such prying gives occasion for slander, judgement and other grievous sins. Why do you need to be concerned about others? Know and examine your own self.Recall your past sins and purge them with repentance and contrition of heart, and you will not look at what other people do.
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.
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.
Condemn only yourself, and you will not be condemned at His second and awful coming. From your whole heart remit the sins of whoever sins before you, and your Father who is in heaven will remit your sins.
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.
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.
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.
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.
This reversal of thoughts is the strongest means, not only for repelling accidental critical thoughts, but also for completely freeing yourself of this vice…
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.
