…[It] is my intention that they be held in due reverence, not for what they are in themselves, but for my sake, because of the authority I have given them. Therefore the virtuous must not lessen their reverence, even should these ministers fall short in virtue. And, as far as the virtues of my ministers are concerned, I have described them for you by setting them before you as stewards of... my Son’s body and blood and of the other sacraments. This dignity belongs to all who are appointed as such stewards, to the bad as well as to the good.
…[Because] of their virtue and because of their sacramental dignity you ought to love them. And you ought to hate the sins of those who live evil lives. But you may not for all that set ourselves up as their judges; this is not my will because they are my Christs, and you ought to love and reverence the authority I have given them.
You know well enough that if someone filthy or poorly dressed were to offer you a great treasure that would give you life, you would not disdain the bearer for love of the treasure, and the lord who had sent it, even though the bearer was ragged and filthy... You ought to despise and hate the ministers’ sins and try to dress them in the clothes of charity and holy prayer and wash away their filth with your tears.
Indeed, I have appointed them and given them to you to be angels on earth and suns, as I have told you. When they are less than that you ought to pray for them. But you are not to judge them. Leave the judging to me, and I, because of your prayers and my own desire, will be merciful to them. 
Is judging the same as criticizing? It’s close. The Random House American College Dictionary defines the word “criticize” as “1. To make judgments as to merits and faults. 2. To find fault.”
Clearly, the Lord wants prayers, not judgment for his priests. Alas, how sad that some are far more ready to judge (and criticize) priests than they are to pray for them! Imagine how much better off the Church would be if all the energy given to criticizing priests and bishops were devoted to prayer and penance for these men; and how much better off those who prayed and fasted would be!

Mary, Mother of Jesus Christ, Eternal High Priest, Mother of all priests, and our Mother, help us respond generously to the Holy Spirit's request, through the voice of His Church, to offer up to God Eucharistic adoration for priests. Amen.
