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

“In this matter it should also be noted that when it is said to the prophet: "The unbelieving and the subverters are with you, and you dwell among scorpions," a remedy of consolation is offered to us, whom it often wearies to live when we do not wish to dwell with the wicked. For we complain why all who live with us are not good. We do not wish to bear the evils of our neighbors; we decree that all ought already to be saints, while we do not wish to be what we must bear from our neighbors. But in this matter it is clearer than light that, while we refuse to bear the wicked, how much we ourselves still lack of goodness. For no one is perfectly good unless he has also been good among the wicked. Hence blessed Job declares of himself, saying: "I was a brother of dragons and a companion of ostriches." Hence the apostle Paul says to his disciples: "In the midst of a crooked and perverse nation, among whom you shine as lights in the world." Hence Peter, the pastor of the Lord's flock, says: "He rescued righteous Lot, oppressed by the injurious conduct of the wicked. For he was righteous in sight and hearing, dwelling among those who from day to day tormented the soul of the righteous man with their lawless deeds."”
