Si autem haec omnia de consummatione saeculi intelligantur, mystice accipienda sunt, ut ita dicamus: Tunc qui sunt in Iudaea, hoc est in confessione verae fidei sunt, fugiant ad montes, hoc est culmen virtutum ascendant, et qui super tectum est, id est qui carnem, qua anima tegitur, superavit, non descendat ad infimos actus pristinae conversationis, neque desideria carnis repetat. Et qui in agro est, id est qui operatur in Ecclesia sicut Paulus plantando, et Apollo rigando, non revertatur tollere tunicam suam, id est non repetat saecularia, quibus se nudaverat.

But if we understand this of the consummation of the age, it's to be taken mystically, in the following way: Then they who are in Judea, that is confessing the true faith, flee to the mountains, that is climb to the top of virtue, and he who is on the housetop, that is who rose above the flesh which is covered by the soul, should not come down to the low acts of the early conversion, and not fall again into the desires of the flesh. And he who is on the field, that is who is planting in the Church like Paul and irrigating like Apollo, should not return to take his coat, that is not return to doing worldly things, making himself naked.

[4] And I heard another voice from heaven, saying: Go out from her, my people; that you be not partakers of her sins, and that you receive not of her plagues.

Huius ingenii superfluum est indicem texere, cuм sole clariora sint eius opera.

It is unnecessary to catalogue the works of his genius, since they are more conspicuous than the sun.

Quam eloquens sanctus Cyprianus, quam fulgens framea eius in litteris eius apparuit.

How eloquent Saint Cyprian was, how radiant his sword appears in his letters.

Desiderasti, Fortunate carissime, ut quoniam pressurarum et persecutionum pondus incuмbit et in fine adque in consummatione mundi antichristi tempus infestum adpropinquare iam coepit, ad praeparandas et corroborandas fratrum mentes de diuinis scripturis hortamenta conponerem quibus milites Christi ad spiritale et caeleste certamen animarem.

You have desired, beloved Fortunatus, that since the burden of pressures and persecutions is lying heavy upon us, and the hostile time of Antichrist in the end and consummation of the world is already beginning to draw near, I would collect from the divine Scriptures some exhortations for preparing and strengthening the minds of the brethren, to animate the soldiers of Christ for the heavenly and spiritual contest.

There are implications to this thread in other areas, and all relate to a critical definition of terms, which as Aristotle and St. Thomas I think agree is a necessary beginning before there can be any reliable discourse.

We see this all over the place: what is "necessity" when it comes to the sacrament of baptism, or when it comes to the Church and salvation; what does the "infallibility" or "indefectibility" of the Church mean, and when is the Magisterium infallible or indefectible (if it is)?  My own view is that the thought and definitions of the theologians, and even the teaching Church (at least most definitely in instances below the level of the universal, ordinary Magisterium certainly, even in the "authentic" Magisterium - witness Pope Francis) created problems in this regard that lead to and inspired the errors of Vatican II.

Dei Filius et generis humani Redemptor Dominus Noster Iesus Christus, ad Patrem caelestem rediturus, cuм Ecclesia sua in terris militante, omnibus diebus usque ad consummationem saeculi futurum se esse promisit.

The Son of God, redeemer of the human race, Our Lord Jesus Christ, when about to return to his heavenly Father, promised that he would be with his church militant upon earth all days even to the future consummation of the age.

Pastor aeternus [...] ita in Ecclesia sua Pastores et Doctores usque ad consummationem saeculi esse voluit.

The eternal shepherd [...] in like manner it was his will that in his church there should be shepherds and teachers until the consummation of the age.

CHAPTER XXVI. Concerning the Antichrist.

It should be known that the Antichrist is bound to come. Every one, therefore, who confesses not that the Son of God came in the flesh and is perfect God and became perfect man, after being God, is Antichrist. But in a peculiar and special sense he who comes at the consummation of the age is called Antichrist.

Are you people seriously dismissing indefectibility as a made-up modern concept?

"Gates of Hell"? Does that not strike any bells?

So too, He said, when He stood before Pilate, “Thou shouldst not have any power against Me, unless it were given thee from above.” [62] It was the will of God; it was the concession of the Father that Pilate had power over His incarnate Son. Again, He said, “Thinkest thou that I cannot ask My Father, and He will give Me presently more than twelve legions of angels? how then shall the Scripture be fulfilled?” [63] In like manner with His Church. Until the hour is come when the barrier shall, by the Divine will, be taken out of the way, no one has power to lay a hand upon it. The gates of hell may war against it; they may strive and wrestle, as they struggle now, with the Vicar of our Lord; but no one has the power to move Him one step, until the hour shall come when the Son of God shall permit, for a time, the powers of evil to prevail. That He will permit it for a time stands in the book of prophecy. When the hindrance is taken away, the man of sin will be revealed; then will come the persecution of three years and a half, short, but terrible, during which the Church of God will return into its state of suffering, as in the beginning; and the imperishable Church of God, by its inextinguishable life derived from the pierced side of Jesus, which for three hundred years lived on through blood, will live on still through the fires of the times of Antichrist.

Quod Ecclesia a perfectione sua fulget in decore justitiae usque ad tempus Antichristi.

Because by her perfection the Church sparkles in the adornment of justice up to the time of Antichrist.

And when the sun was setting, a deep sleep fell upon Abram, and a great and darksome horror seized upon him.

cuмque sol occuмberet, sopor irruit super Abram, et horror magnus et tenebrosus invasit eum.

The setting of the sun signifies the end of the age, when due to Antichrist there shall be gloomy trembling, that is persecution or confusion.

Solis occubitus finem saeculi significat, quando per Antichristum tenebrosus horror, id est persecutio vel perturbatio futura est.
