I have been studying the emergent/friendly seeker churches and the chrislam churches and what they are doing. The pastors who teach this tripe are certainly in trouble for teachers are judged more harshly. In Galatians 1:9 Paul said that anyone who preaches a different gospel from the one he preached let him be eternally condemned. Does this mean they can lose their salvation?
No born again believer can become unsaved for any reason. If any of these pastors were once saved they are always saved, but their deeds on Earth could all be burned up in the fire of judgment (1 Cor. 3:10-15). Judging from the doctrine they’re teaching, it’s possible many of them were never saved in the first place.
