In the Church, from the beginning, there are some who are written in the book, and others, who aren't. The "mystery of iniquity" (2 Thess 2) are the latter. They are members of the Church, i.e. they are "called", but they're not predestined, i.e. "chosen". In Mt 13, you got the wheat and the cockle growing in the field/Church.
One day, the Lord will take away the peg (tent-nail) and the tabernacle/tent/Church will collapse (Is 22:25). Neither Antichrist, nor the devil are able to bring down the Church.The gates of hell won't prevail. Rather the Lord will take away the mass (Dan), take away the pope (Is 22:25), and take away the shepherds, and let most Catholics fall into apostasy, such that Antichrist and the devil get their share, the birds get their great supper of God (Rev 19:17).
Q: Why does God do that?
A: "because thou hast not known the time of thy visitation" (Lk 19:44)
Jerusalem/the Church hasn't known the time of the first/second coming of Christ. Pope Leo XIII knew that St. Michael and his angels fought with the dragon (Rev 12), St. Pope Pius X said that things look like Antichrist was already born, and he was (whether Roncalli or Montini). But right after Pius X the Church stopped to care about the topic. Catholics were reeducated to stop being "prophets of doom" (Roncalli before the robber council).
Christ made blind men see, lame men walk, and dead men live. The announced signs. But Jerusalem didn't know the time of her visitation. The Gospel had been preached everywhere, most Catholics were liberal, but they didn't know the time of the Church's visitation. Even trads up to this day say: let's continue the Church, let's continue the mass, let's rebuild the Church, etc.
But our Lord already pulled the peg, pulled the plug, because thou hast not known the time of thy visitation.
The beast in Rev 13 is the sum of the beasts of Daniel. That's Fɾҽҽmαsσɳɾყ/liberalism/modernism/... transforming the "mystery of iniquity" part of the Church (not written in the book) into beast. All confessions and deeds (forehead/hand) in favour of this world mark you as part of the beast. You're part of the beast, if thou hast not known the time of the visitation of the Church.
If you think about Pfizer, Kushner, Schwab, Graphene, or any other type of Jooo, you missed the sound of the trumpet!
Those who don't believe, are already damned. The Apocalypse is about the bipartite Church, about the separation of the wheat from the chaff, "within" the Church.
I think that I agree with most of what you said. Anyway, close enough, because there is always some wiggle room in the interpretation of prophecy and the application to the reality we are experiencing.
One point of disagreement is with your statement that "the time of thy visitation" has already passed. I do not think so. I believe that the concept of "the visitation" in prophecy is the same thing mentioned by Our Lady at Garabandal: the Warning (
aviso).
To understand better what is meant by the prophetic reference to "visitation," a Catholic needs to have in mind what occurs during an "apostolic visitation" from the Vatican. Officials are sent to "audit" and "make recommendations" and, if necessary, "warn" the religious order being visited.
The Garabandal seers describe "The Warning" as good from some and bad for others. For those living in God's grace, the "aviso" will be confirmation of their actions and an encouragement. For those in a state of mortal sin, it will be a shocking "Warning" to turn away from sin. So that description sounds much more like "an apostolic visitation" than it do a simply negative "warning." Anyway, the "aviso" has not happened yet according to Conchita Gonzales, the main Garabandal seer. She said in the 1970s that it would happen when she was "very old." She is around 72 years old now.
The Garabandal timeline squares with my interpretation of Bible prophecy as well. On the DRBO.org website, in the Latin Vulgate section, you can search for "
visitationis" and you will see the instances of the word are almost always prophetic. 13 of 18 instances are in the book of Jeremias. Jeremias deals with the period of the final kings of Juda (i.e., the NuChurch popes): Josiah (i.e., John Paul II), Joakim (i.e., Benedict XVI) and Sedecias (i.e., Bergoglio the usurper "pope"). It is during this period that Jeremias is warning about a future "visitation." So I believe this event is coming soon. Could be days, months, years, but not decades from now. My best guess is within 3 years.
