It is a very dangerous movement which degrades the gospel message at its core, introducing mysticism and eastern religious theologies. It is basically spiritualism.
This website is one that tries to be unbiased in either direction and just tell what a religion believes, which is why I include it here.
Then from an Adventist perspective I am including the video series that was done a couple of weeks ago talking about the emerging church and spiritual formation in our churches and schools.
This is the first of the series which is all about the emerging church and what it's doing in the Adventist church in particular. The series is called Omega Emerging. There are about 6 or 7 videos.
I hope others will be able to see how dangerous this movement is and warn others to anchor themselves in Jesus and His Word, because Satan is coming in like a roaring lion seeking whom he may devour. Spiritualism is filling our whole world in television and books, and now even in church. Do not accept it, speak out against it.
If you want more proof just google Emergent Church, or Spiritual formation and you will find out a lot about it from many different perspectives. Of course we must base our perspective on the Biblical truth perspective.
Isa 8:20 To the law and to the testimony: if they speak not according to this word, it is because there is no light in them.
