They claim it is Christ they are bringing but they are bringing something else, and it clearly appears they pervert the gospel of Jesus Christ. We must be a church "rightly dividing" what is presented, in order to keep our understanding, not only of the gospel, but of the Bible itself, in proper perspective. We cannot change it to cater to the current fads or morph the "celebration style" of worship under another name to fool the people. God knows and He will judge these people who are doing this, it is at great peril to their own souls and even worse to the members who don't see what they are doing. I was in a celebration church for years and never grasped the danger till afterwards, Ellen White was slowly muted then taken away, the music with the band and drums became the driving force and focus, the doctrines became watered down till Adventism was almost no longer even part of the beliefs, and we were left open to current fads and strange doctrines, introducing another Jesus, another Spirit, another gospel. That is why we see Adventist churches where any sin, or abomination to God is now become acceptable, come in as you are was the overriding mantra we were given, but they forgot about the repent and sin no more and be saved part.
I was young and gullible then, and Willow Creek was but a name and celebration but a style, and it has morphed and mutated. But as the saying goes.. Fool me once, shame on you; fool me twice, shame on me, but fool me the third time, I don't think so.
