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.
A man may seem to be silent, but if his heart is condemning others, he is babbling ceaselessly. But there may be another who talks from morning till night and yet he is truly silent, that is, he says nothing that is not profitable.
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.'
Abba Or used to say this, 'Do not speak in your heart against your brother like this: 'I am a man of more sober and austere life than he is,' but put yourself in subjection to the grace of Christ, in the spirit of poverty and genuine charity, or you will be overcome by the spirit of vainglory and lose all you have gained. For it is written in the Scriptures: 'Let him who stands take heed lest he fall.' (I Corinthians 10:12) Let your salvation be founded in the Lord.'
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.
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.
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.
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.
The Church Fathers regard Sacred Tradition as the safe guide in the interpretation of Holy Scripture and absolutely necessary for understanding the truths contained in the Holy Scripture. The Church received many traditions from the Apostles... The constitution of the church services, especially of the Divine Liturgy, the holy Mysteria themselves and the manner of performing them, certain prayers and other institutions of the Church go back to the Sacred Tradition of the Apostles.
He who busies himself with the sins of others, or judges his brother on suspicion, has not yet even begun to repent or to examine himself so as to discover his own sins...
Be attentive, my child, that you not judge any soul. For God steps aside from the one who judges his neighbor, and he falls, in order to learn to have sympathy for his sick brother.
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.
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.
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.
They (namely the Apostles) have not handed down everything in writing, but have also delivered many things in unwritten form. The former and the latter are equally trustworthy, and so we also consider the [unwritten] Tradition of the Church to be trustworthy. Is it Tradition? Seek no further.
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.'
Did you see that brother who was negligent and lazy, who did not go down to the all-night vigils and did not do his duties, whom the brothers knew and held to be a negligent brother? When, therefore, he became sick and the hour of his death drew near, the brothers gathered to hear something beneficial, or to comfort him, or in case he wanted to say something to them, but they saw him rejoicing, cheerful. One brother was scandalized and said, But what do we see in you, brother? We see you rejoicing, while you approach death? But our thought says to us that you were not a violent man and how do you have this courage and this rejoicing face? On what do you base this thing? Yes, brothers, he said, really I was a negligent person and I did not fulfill my duties. But I achieved one good thing, by the grace of God -- not to criticize any brother and not to scandalize anyone; and never did I allow my heart to have something against my brother of the monastery when the sun set. And inasmuch as I did not judge my brother, I believe that God will not judge me, even me, for He said, Judge not, that you not be judged (Mt. 7:1); and as long as I did not judge, I will not be judged. The brothers marveled and said, Brother, very easily you found the way of salvation. And the brother died with much joy.
