The Antichrist? 2 John 1:7, 9 tells us that he is the one who does not confess Jesus as the Christ coming in the flesh (incarnate). Those close to Jesus walked a long way with Him, only to deny Him in the end (John 6:66-67).
If you ask why Satan broke away from Most Holy Triune God, most mention Satan's pride of wanting to be No. 1. Saints say Satan didn't want God to lower Himself to man and lift him to God's likeness. Satan didn't want God to share His divine life.
This is the Catholic Eucharist: total unity — the only means of sharing in Christ's sacrifice. The family of God involves a higher relationship than merely "personal."
Why does Satan hate Mary more than any other human creature? It was through her flesh that Christ united to man on the cross. The "new and living way" of Hebrews 10:20 is the fruit of His sacrifice — His flesh in he Eucharist of John 6. Belief of John 6:47 must extend to reception of Him in Holy Communion.
Post-Vatican II popes, presidents and so-called prophets treat Russia and China as non-existent. As insinuated by Fatima, atheism will fight God to the end. Much of this hatred will be directed toward the Jews. But Christ, in Romans 8:28-29, will bring many Jews (under "extreme" pressure) into the family of Most Holy Triune God — through the Eucharist.
Middle East tension is stirred up by atheistic Russia and China. Even North Korea has no nuclear weaponry unless it is given to them. The "compromised" U.S. is not to be excused. Agents are behind much of what you "assume" to know. In the so-called democracy movement, once-tolerated Catholics are persecuted in Egypt and Libya.
It is sad that only 15 percent of Israelis know anything about God in general. How will they come into Most Holy Triune God's family? Not because they love God of Romans 8:28, but because of 29 (His great love for them).
