Based on the available Ellen White books, there is no direct statement where Ellen White says that the Seventh-day Adventist Church would "almost become Babylon," "sister to Babylon," or "Babylon itself." However, she does discuss the concept of "Babylon" in relation to churches that have become corrupt, apostate, or have allied themselves with the world, particularly in the context of Protestant churches that have departed from biblical truth.
Key points from her writings:
- Babylon is used as a symbol of an apostate church, especially in Revelation 17, and is applied to churches that have become corrupt and have sacrificed truth for worldly alliances (see
GC 382.3,
4SP 233.1).
- She states that the term "Babylon" may be appropriately applied to religious bodies that were once pure but have become corrupt, especially those that follow the example of Rome in seeking the favor of the world (
GC 383.1,
4SP 232.2).
- Ellen White warns that as churches depart from truth and ally with the world, the time will come when God's people must separate from them (
4SP 239.3).
- She never directly applies the term "Babylon" to the Seventh-day Adventist Church, nor does she say it would become "sister to Babylon" or "almost Babylon." Her warnings are generally directed toward Protestant churches that have rejected truth and embraced worldliness.
In summary, Ellen White uses the term "Babylon" to describe apostate churches, particularly those that have rejected biblical truth and allied with worldly powers, but she does not specifically say that the Seventh-day Adventist Church would become Babylon, almost Babylon, or sister to Babylon.
