The term "Jehovah's Witnesses" does not appear in the Bible itself; rather, it is a designation for a religious group that emerged in the late 19th century in the United States. The name reflects the group's emphasis on the use of "Jehovah" as the personal name of God, which they derive from a particular rendering of the Tetragrammaton (YHWH) found in the Hebrew Scriptures. This emphasis aligns with passages such as Psalm 83:18, which states, "That people may know that you, to whom alone the name is Jehovah, have made the Most High over all the earth" (ASV).Jehovah's Witnesses believe they are restoring true Christianity, following the teachings of the Bible, particularly emphasizing the Kingdom of God and the role of Jesus Christ as the Savior. They interpret Scriptures like Matthew 28:19-20, the Great Commission, as a command to preach their understanding of God and His Kingdom. Their theology diverges from mainstream Christianity in several key areas, including views on the Trinity and the nature of Jesus, which they believe is distinct from God the Father. Their practices include door-to-door evangelism and a strict code of ethics, all of which they believe are biblically mandated.
