Thank you for pointing out the CCC, the best source to go to when in doubt of official Catholic teaching! Then, yes, justice is a perfect relationship. Justice here is what many translations of the Bible call “righteousness”;

dikaios; as Joseph was called.
Yet I cannot ignore the aspect of God also using His “righteous” wrath against certain people, this is evidenced in our faith. God punished people in the OT, but this is not simply an OT reality; there is the example of Ananias and Sapphira in Acts 5:1-11. Perhaps you are in complete agreement with me, so forgive me if I missed that. St. Augustine said, “justice is that virtue which gives every one his due” (City of God, Book XIX, ch. 21).

St. Augustine. yes.
You have an aptitude for scholarly study.
I, too, do not wish to artificially break the “OT God” from the new.
Our conversation is focused on a narrow issue regarding God’s attributes when we talk about the
need for atonement and wrath; and there is something subtle here I want to draw your attention to – or at least, I have been trying to do so. (

bear with me )
I meant to distinguish the process ( pedagogy ) of learning about God, from their Goal, lawfulness.
A person (even God) may want one thing, but do another. ( 1Timo 2:4 )
Death itself is a punishment; and we have, for example, the example of the thief “We are only paying for what we have done”, and the example of purgation (prefiguring purgatory) by Joshua 7:19-26, and the example of the Maccabees praying for the dead sinners.
In all these examples, eternal wrath is not guaranteed; nor even is it guaranteed in the Case of Annanias and Sophira. Yet, God’s “Justice” as spoken of by Faustina is referring to the final Judgment.
It is perhaps not obvious in the case of Annanias and Sophira; so I’ll elucidate.
When someone is condemned to wrath – there is no point in doing a corporal work of mercy. Throughout the O.T. the bodies of Jezebels’ and ultimate traitors to the faith are not buried. They are left for the dogs to eat, and the worm to attack; for the ultimate sins, their bones are placed in a fire who’s heat is raised high enough to calcine the bones and return them to dust. (A big deal is made of this. They “burnt up his bones”; cf. the church’s historical ban on the cremation of the faithful.)
Annanias and Sophira were buried;
But there is more; In their case, it was a priest – St. Peter – in the context of the power of confession (during a legal cross examination) who passed judgment upon them. The Holy Spirit had no need of a trial or cross examination to condemn and judge them. For this reason, there are two points to bear in mind – 1) the Judgment came through an incarnate persona Christi, who only came into being in the fullness of time; 2) such wrath does not apply (a-priori) to history without that incarnation; or the logic leading to the
necessity of the incarnation for the purposes of atonement. { We may speak of finding Christ prefigured in the O.T. but even then, Jesus only guarantees that it is in the Prophets that such is found; St. Augustine not withstanding.)
The case of Annanias and Sophira, then, is pedagogy; but not necessarily about the eternal.
Therefore, in light of the this, the passage in the Catechism makes complete sense. In the New Covenant, it is justice to help the poor and do socially good deeds (“social justice”), because it is God’s will as revealed in Christ and His love for the poor; it is justice for God to forgive our sins in Christ, since He is just, and bore our sins, so it is only “normal” (a wrong term to use for God but for lack of a better word) for a loving God to forgive the sins of those who believe in His Son and follow His commandments; and it is justice for God to render to the wicked their due of punishment, something revealed throughout Scripture time and time again.
What I see
clearly revealed is a temporal rendering of wrath; and the self defense of God’s holy name ( for example,in Sodom’s act against the tri-angels )
In all these examples the word “justice” could easily be replaced by “right”, i.e., it is right to do such-and-such because the holy and loving God wills it. It would seem to me that the virtue of justice is to do the will of God, simply put. In other words, God’s wrath is a part of His justice/goodness, and goodness by definition hates that which is evil, sin.
Yes; I agree.
Sin and righteousness can not dwell together (But reacall 1Tim again).
But I don’t clearly see (perhaps I will?) how it is that images (?hyperbolic?) of a human wrath projected onto God can be guaranteed to accurately represent the “why” of wrath.
I am more concerned with human mis-interpretation of the intricacies and subtleties involved, than I am with it’s existence.
I agree, hate does not have to be malicious; when the Psalms and Prophets speak of God’s hatred, it’s as though this kind of hatred springs not at all from malice but from a loving, caring and wounded husband…
if He could even be pushed by anything, to decide to send His Son to save us (e.g. Isaiah 42:14); therefore, again, His Son’s mission is justice personified.
Point taken.
Regarding not every sin meriting wrath, what do we mean by wrath? For Catholic teaching is that even the most minor of venial sins, though forgiven, will have to be paid for, either here or in Purgatory (or hell eternally for the unrepentant);
Let me think about this some more. You’re very observant. Could you cite a specific reference, so I may review it in detail ?
