StandFirm Proves that Jehovah's Witnesses "stand condemned"

I've pointed out that Jehovah's Witnesses preach a different gospel from that of the 1st century, and therefore stand condemned, per Galatians 1:8.

StandFirm has kindly affirmed my position:

What Galatians 1:8 and other such scriptures are speaking about is the overall message that someone might be preaching. If an individual's or group's overall message is different than the one the Christians of the 1st century preached, then they fall under that condemnation.
