This brings to mind an interesting issue -- is it possible for the church to become part of Babylon?

Many people would say "no", and often cite multiple statements in the early chapters of Testimonies to Ministers.

But if we go deeper into the matter, it appears that such a thing is possible, if the abominable practices of the world are brought into the church and ultimately accepted.

The first quote below mentions becoming a "sister to fallen Babylon", and both use the Revelation 18:2 language about becoming a "cage of every unclean and hateful bird", which is a reference to Babylon.

We must as a people arouse and cleanse the camp of Israel. Licentiousness, unlawful intimacy, and unholy practices are coming in among us in a large degree; and ministers who are handling sacred things are guilty of sin in this respect. They are coveting their neighbors' wives, and the seventh commandment is broken. We are in danger of becoming a sister to fallen Babylon, of allowing our churches to become corrupted, and filled with every foul spirit, a cage for every unclean and hateful bird; and will we be clear unless we make decided movements to cure the existing evil?  {21MR 380.1}

It is the work of the Christian to mend, to restore, to heal. This healing process saves many a soul and hides a multitude of sins. God is love; God is, in Himself, in His essence, love. He makes the very best of what appears an injury, and gives Satan no occasion for triumph by making the worst appear and exposing our weakness to our enemies. The world must not be introduced into the church, and married to the church, forming a bond of unity. Through this means the church will become indeed corrupt, and as stated in Revelation, "a cage of every unclean and hateful bird."  {TM 265.1}
