He who speaks dispassionately of his brother's sin does so either to correct him or to benefit another. If he speaks for any other reason, either to the brother himself or to another person, he speaks to abuse him or ridicule him.
I suppose that it is sometimes better to fall oneself and rise, than to judge one's neighbor; because one who has sinned is incited to self-abasement and repentance, while he who judges one who has sinned becomes hardened in an illusion about himself and in pride. Therefore everyone must guard himself, as much as possible, so as not to judge.
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.'
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.
Let us strive with all of our power never to put our trust in our own conjectures. For nothing separates us so completely from God or prevents us from noticing our own wrong doing or makes us busy about what does not concern us, as this. No good comes from it but only troubles without number and they leave us no time to acquire the fear of God. Should worthless suspicions germinate in our minds, let us turn them into charitable thoughts and they will not harm us. For entertaining suspicions is wrong and it never allows the mind to be at peace.
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.
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.
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.'
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.
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 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.
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.
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.
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?'
