Why "all the churches are in Babylon"?!
In Revelation 18:2 and 18:4 God calls His People out of Babylon; not from a country, but from a faith (institution). But what exactly does that mean and why is it called Babylon?
In ancient Babylon, the triune sungod was worshiped: Baal with holy sun-day, Easter with holy Easter & Carnival and child god Tammuz/Attis with holy Christmas = winter solstice.
Also RC church founder Roman emperor Constantine was a triune sungod worshiper until his death and he inserted that idolatry in the RC church he founded, which is also called "the Mother Church". And so the triune godhead came into existence with 3 names that are no names and with Holy Sunday, Easter and Christmas on the winter solstice, so that everyone knows that it is actually Babylonian idolatry...
Luther may have protested against the excesses of his RC church, but not against the cause of it: the corrupt triune godhead, so that all Protestant churches and later churches adopted that idol from Babylon and worshiped it as if it were equal to 1 true God YHWH who is a Spirit (John 4:24) and to 1 Lord Christ Jesus, John 17:3, John 14:1 with a resurrected body, as an example for us, Rom 8:11. The freemasonry Jehovah idol of JW founder CT Russell is also that idol from Babylon. And also the condensed Messianic biune godhead is that same idol from Babylon. All churches are in Babylon with this idol godhead.
Better even: they all join that Mother Church from Babylon; through treaties, collaborations, organizations, activities, and so on. And so those churches associated with her are actually her daughters. Revelation 17:1 and 19:2 calls that Mother Church from Babylon a great harlot: an adulterous cq idolatrous institution of faith. What will the daughter churches be then? Same thing: idolatrous creeds with the same idolatry from Babylon.
How do you leave Babylon?
1. Believe as Christ says in John 17:3 and John 14:1, namely in 1 true God who is Spirit+in 1 Lord Christ Jesus.
2. Lay that faith likewise, namely baptism unto Jesus, Acts 19:5, followed by prayer with the laying on of hands leading to God and reception of the Spiritual Gifts, Acts 19:6.
This is how you leave Babylon spiritually and in faith. However, you must also physically leave that spiritual Babylon:
3. Cancel your membership by registered letter and request proof of deregistration!
Of course, being a Christian is more than just leaving Babylon. Being a Christian also means going out into your personal world with the Gifts of the Spirit in order to grow in the Fruit of the Spirit. Thus you will see the Son of Man, the Bridegroom, coming again with oil in your lamp and with spare oil, Matthew chapter 25.
So hasten to leave that spiritual church Babylon. Don't delay, because that process of abandonment and change to becoming a true Christian takes time!
