Gregory the Great — on Ezek 2:6 (Homilies on Ezekiel, Book 1, Homily 9)

“Hence blessed Job, when through the tongues of detracting friends he suffered the darts of words amid the pains of his wounds, immediately ran back in thought to his conscience, and looked to where he might have a firm mind, saying: "Behold, for my witness is in heaven, and my advocate is on high." Who also added: "My friends are full of words; my eye drips tears to God." For in everything that is said about us, we must always silently return to the mind, seeking the inner witness and judge. For what does it profit if all praise when conscience accuses? Or what can it harm if all disparage us, and conscience alone defends us? Blessed Job therefore, persisting with unbending mind amid the tongues of detractors, because he saw himself attacked on earth by false speeches, sought a witness in heaven. Hence Isaiah says: "My people, those who call you blessed deceive you, and destroy the way of your steps." Lest this people attend to the words of their own praise and perish more deeply in faults, it is immediately said whom he should look upon, whose judgment he should fear, when it is added: "The Lord stands to judge, he stands to judge the peoples." As if it were openly said: Why do you follow human judgments, you who know that the heavenly judge stands above you?”
