I do not know what all these churches teach but I just met a believer from the church here in Denver who is as sound as they get. Affirmed the essentials of the faith and did not deny the trinity nor the divine Christ. Affirmed the authority of all the Bible, the reality of Hell, salvation by grace, justification by faith, and such. I know that they have some false teachings in the WOF message but what I cannot say is that all attenders in these churches are following another gospel. Or perhaps the person I spoke with did not know fully what they teach.
