"If a man who engages in many ascetic labors sees someone wholly in a state of sin or negligence, and denigrates him, all of his repentance is in vain, since he has rejected a member of the Body of Christ by judging him, by not leaving the judgment to the Divine Judge, and by not attending to his own sins. For
in the present life, we are all, as it were, in a doctor's waiting room: one person is suffering from a disease of the eyes, another has a pain in his hand, another has an abscess, or whatever other illnesses there may be. Some of these wounds have already been healed; but when one who has been healed of them eats something harmful, then he suffers a relapse.
"Such is the case also with one who is in a state of repentance and who judges or despises another: he undoes his repentance. Now, if a number of people are in a waiting room, each with a different ailment, and one of them cries out from his own suffering, is someone else going to ask him: 'Why are you crying out?' Is not each person concerned with his own malady?
If I had the pain of my own sins before me, I would not be able to see anyone else sinning. Each person in the waiting room is keeping watch over himself, in accordance with the doctor's instructions, by not eating anything detrimental to his wounded condition. Who is there who is not wounded?
A brother asked Abba Poimen: "If I see a brother about whom I have heard that he is a sinner, I do not wish to take him into my cell; but if I see a good brother, I rejoice with him." The Elder replied: "If you do a little good to the good one, you ought to do twice as much good to the one about whose sin you have heard. The latter is the one who is ailing. [If you do this,] God will have mercy on you, too.

Do not regard the feelings of a person who speaks to you about his neighbor disparagingly, but rather say to him: "Stop, brother! I fall into graver sins every day, so how can I criticize him?" In this way you will achieve two things: you will heal yourself and your neighbor with one plaster. This is one of the shortest ways to the forgiveness of sins; I mean, not to judge. "Judge not, and ye shall not be judged."
Hasty and severe judges of the sins of their neighbor fall into this passion because they have not yet attained to a thorough and constant remembrance and concern for their own sins. For if anyone could see his own vices accurately and without the veil of self-love, he would worry about no one else in this life, considering that he would not have time enough for mourning for himself, even though he were to live a hundred years, and even though he were to see a whole River Jordan of tears streaming from his eyes. I have observed such mourning, and I did not find in it even a trace of calumny or criticism.
Ladder of Divine Ascent, Step 10: On Slander. 10.7 and 10.10. HTM, 1991.
As we ponder the above words of our holy fathers, my dear brothers and sisters in Christ, with great fear and trembling and in remembrance of our innumerable sins, for each of which we will give account at the most holy judgment seat of our Christ, let us resolve firmly not to judge the sins of another, nor to commit the sin of slander, that is, of making public the sins of others. When there is a necessity to report the sins of another person to the lawful authority, let it be done with discretion and humility, and not in a way that is designed to publicly humiliate.
Let us note, too, that NONE OF THE ABOVE is morally relativistic; i.e., none of the above means that a sin is not a sin, or that an evil deed is not an evil deed. Evil is evil. We will be called to account. The Gospel of Christ calls us to a high standard morally. We are to be pure, to be chaste, to avoid giving offense or scandal, not given to greed, not corrupt, and so forth. The fact that we are not to JUDGE others for their sins and failings does not mean that their sins are somehow not sins. It simply means that WE ARE NOT THE JUDGES. Christ is the ultimate Judge of the human race. We as Christians do not stand as judge and jury over our brothers and sisters. We are fellow slaves under our common Lord and Master, Jesus Christ.
Or to put it another way: We all are lying here in the hospital of the Church. Are you among the sick, or are you the doctor? If you are not the doctor, then who are you to be giving out free medical advice to the other patients?
