Psalms 54:16

28. We, however, are certain that no one could ever have been warranted in separating himself from the communion of all nations, because every one of us looks for the marks of the Church not in his own righteousness, but in the Divine Scriptures, and beholds it actually in existence, according to the promises. For it is of the Church that it is said,“As the lily among thorns, so is my love among the daughters;” which could be called on the one hand “thorns” only by reason of the wickedness of their manners, and on the other hand “daughters” by reason of their participation in the same sacraments. …

15. “Let there come death upon them, and let them go down unto Hell living” ( ver. 15 ). How hath he cited and hath made us call to mind that first beginning of schism, when in that first people of the Jews certain proud men separated themselves, and would without have sacrificed? A new death upon them came: the earth opened herself, and swallowed them up alive. “Let there come,” he saith, “death upon them, and let them go down into Hell living.” What is “living”? knowing that they are perishing, and yet perishing. Hear of living men perishing and being swallowed up in a gulf of the earth, that is, being swallowed up in the voraciousness of earthly desires. …

25. “Let the table of them be made in their own presence for a trap” ( ver. 23 ). Like the trap which for Me they set, in giving Me such a draught, let such a trap be for them. Why then, “in their own presence”? “Let the table of them be made for a trap,” would have been sufficient. They are such as know their iniquity, and in it most obstinately do persevere: in their own presence there is made a trap for them. These are they that, being too destructive, “go down into Hell alive.” Lastly, of persecutors what hath been said? Except that the Lord were in us, perchance alive they had swallowed us up. What is alive? Consenting to them, and knowing that we ought not to consent to them. Therefore in their own presence there is made a trap, and they are not amended. Even though in their own presence there is a trap, let them not fall into it. …

But what sort of a thing is this, that sometimes we fancy that we are patient because when provoked we scorn to answer, but by sullen silence or scornful motions and gestures so mock at our angry brothers that by our silent looks we provoke them to anger more than angry reproaches would have excited them, meanwhile thinking that we are in no way guilty before God, because we have let nothing fall from our lips which could brand us or condemn us in the judgment of men. As if in the sight of God mere words, and not mainly the will was called in fault, and as if only the actual deed of sin, and not also the wish and purpose, was reckoned as wrong; or as if it would be asked in the judgment only what each one had done and not what he also purposed to do. …

But, on the other hand, those who censure wrong things and yet avoid them not are to be admonished to weigh circumspectly what they can say in their own excuse before the strict judgment of God , seeing they are not excused from the guilt of their crimes, even themselves being judges. What, then, are these men but their own summoners? They give their voices against misdeeds, and deliver themselves up as guilty in their doings. They are to be admonished to perceive how it even now comes of the hidden retribution of judgment that their mind is enlightened to see the evil which it perpetrates, but strives not to overcome it; so that the better it sees the worse it may perish; because it both perceives the light of understanding, and also relinquishes not the darkness of wrong-doing. …
