So I guess we might agree. But we really don't because the people you are referring to REFUSE to wear the name Christian. Now, I do not judge their salvation. That is up to God. I don't know if they are going to hell or heaven. You do judge their salvation by saying they are going to heaven. You are in the salvation judging business and I am not.
Furthermore, I do not believe that those who wear the label "Christian"
are the only ones saved.
