What do Jehovah Witnesses believe? The Jehovah’s Witnesses believe in a counterfeit Christian religion. They have a leader who claims to be uniquely called by God. Charles Taze Russel was the leader of the Jehovah’s Witness group that formed in 1870. The group has now grown to about 8.7 million actively involved people. They require the study of books other than the Bible, and their “revealed truths” supersede or contradict the Bible. They claim to be the only true church and do not hold back from criticizing all Christian churches. Cults use excessive control by the leaders of the group, and they often claim new revelations from God and change their beliefs with new revelations.what do jehovah witnesses believe
