Yes if one doesn't keep on top of things like I didn't for a while in my church, one can be deceived for a season. The Holy Spirit is going to lead that person out of a church eventually. The elect person should have "red flags" and feel a "disconnect" with the error around them at some point. They should want to leave in their heart at least. That's my opinion.

Something I pondered about my prior church was are these pastors saved? Well I really don't know for sure, but then I concluded does it really matter or not? If saved (and they themselves are being deceived) they are still in error and I cannot stand with them. My trust in their discernment was lost either way. Maybe if they are in the kingdom, God is using our family leaving against them to help correct them. Who knows except the Lord of course. All I knew is that I didn't belong there. And honestly I don't miss our church at all after being gone over a month. Actually after visiting another (more biblically grounded) church in the last two weeks and hearing some "meat" in the sermon it kind of makes me more angry all the "wasted" time we spent at the prior church. Well no use crying over spilled milk. I am just thankful that we are gone.

My church wasn't quite like the one on the Nightline Show. Our church did have candles around and a "band" for worship (which I didn't like because I could never hear myself sing). And we did have new art on the walls with the new pastor though. And his response to why we had this art is that it is there to help those who find art as a way to connect with God. Hmmm.....how does that hold water with the 2nd and 3rd commandments?? (at least that was one of my thoughts to his statement). To me that is one of the disturbing things I saw in the Emergent Church movement and in my church - the issue of catering to people's ways they want to connect with God. The Bible becomes just one of the ways to connect with God.
