Psalms 139:22

Yet, it is not hard for us, if we wish it, to take up a love for justice and a hatred for iniquity. God has advantageously given all power to the rational soul, as that of loving, so also that of hating, in order that, guided by reason, we may love virtue but hate vice. It is possible at times to use hatred even praiseworthily. "Have I not hated them, O Lord, that hated you and pined away because of your enemies? I have hated them with a perfect hatred."

And then He tells what meanwhile, during this whole time when He already has risen, and remains still with the Father, He suffers by the intermixture of sinners in His Body, the Church, and by the separation of heretics. "If Thou, O God, shall slay the sinners (since You shall say in Your thought, Depart from Me, you men of blood), they shall receive in vanity their cities" (ver. 19-20). The words seem to be connected in this order; "If Thou, O God, shall slay the sinners, they shall receive in vanity their cities." Thus are sinners slain, because, "having their understandings darkened, they are alienated from the life of God." [Ephesians 4:18] For on account of elation they lose confession, and so they are slain, and in them is fulfilled what Scripture says, "Confession perishes from the dead, as from one that is not." [Sirach 17:28] And so "they receive in vanity their cities," that is, their vain peoples, who follow their vanity; when, puffed up by the name of righteousness, they persuade men to burst the bond of unity, and blindly and ignorantly follow them, as being more righteous....But now the Body of Christ, the Church, says, Why do the proud speak falsely against me, as though I were stained by other men's sins, and so, by separating themselves, "receive in vanity their cities"? "Have not I hated those who hated You, Lord?" [Psalm 139:21]. Why do those who are worse themselves require of me to separate myself in body as well as spirit from the wicked, so as to root up the wheat, together with the tares, before the time of harvest, that before the time of winnowing I lose my power of enduring the chaff; that before all the different sorts of fishes are brought to the end of the world, as to the shore, to be separated, I tear the nets of peace and unity? Are the sacraments which I receive, those of evil men? […]

I also ask and beg of you to expound for me what [Paul] says to the Romans, for I admit I have very poor sight for this opinion of the apostle about the Jews, where he says, "As concerning the gospel, indeed they are enemies …

Am not I grieved with those that rise up against thee, grieved to see their rebellion and to foresee their ruin, which it will certainly end in?" Note, Sin is hated, and sinners are lamented, by all that fear God. " I hate them " (that is, " I hate the work of them that turn aside, " as he explains himself, Ps. ci. 3 ) " with a sincere and perfect hatred;

I hate them with perfect hatred. He does not leave it a matter of question. He does not occupy a neutral position. His hatred to bad, vicious, blasphemous men is intense, complete, energetic. He is as whole hearted in his hate of wickedness as in his love of goodness. I count them mine enemies. He makes a personal matter of it. They may have done him no ill, but if they are doing despite to God, to his laws, and to the great principles of truth and righteousness, David proclaims war against them.
