Yet the Bible teaches there is but "one faith" Ephesians 4:5 and not many faithS as denominationalism falsely claims. Therefore the often asked question "what faith are you" has no Biblical basis whatsoever. Furthermore, Jesus refers to this one faith as 'truth' (John 17:17) and truth NEVER contradicts itself. Heresy then is anything that goes against that one faith, that one truth, that one body of information given us within the pages of the NT. Many, many heresies are found within the teachings of many groups but no heresy is ever found within the one faith. There will not be any agreement among people over that one faith in this life, therefore on judgment day there will be a permanent, everlasting separation between those who correctly had that one faith from those that sincerely thought they held it correctly.
