Names of God in Christianity in the context of "Tetragrammaton"

Jehovah's Witnesses is a nontrinitarian, millenarian, and restorationist Christian denomination, stemming from the Bible Student movement founded by Charles Taze Russell in the nineteenth century. Russell co-founded Zion's Watch Tower Tract Society in 1881 to organize and print the movement's publications. A leadership dispute after Russell's death resulted in several groups breaking away, with Joseph Franklin Rutherford retaining control of the Watch Tower Society and its properties. Rutherford made significant organizational and doctrinal changes, including adoption of the name Jehovah's witnesses in 1931 to distinguish the group from other Bible Student groups and symbolize a break with the legacy of Russell's traditions. In 2024, Jehovah's Witnesses reported a peak membership of approximately 9 million worldwide.

Jehovah's Witnesses are known for their evangelism, distributing literature such as The Watchtower and Awake!, and for refusing military service and blood transfusions. They consider the use of God's name vital for proper worship. They reject Trinitarianism, inherent immortality of the soul, and hellfire, which they consider unscriptural doctrines. Jehovah's Witnesses believe that the destruction of the present world system at Armageddon is imminent, and the establishment of God's kingdom over earth is the only solution to all of humanity's problems. They do not observe Christmas, Easter, birthdays, or other holidays and customs they consider to have pagan origins incompatible with Christianity. They prefer to use their own Bible translation, the New World Translation of the Holy Scriptures.

Jehovah (/dʒɪˈhoʊvə/) is a Latinization of the Hebrew יְהֹוָה‎ Yəhōwā, one vocalization of the Tetragrammaton יהוה‎ (YHWH), the proper name of the God of Israel in the Hebrew Bible / Old Testament. The Tetragrammaton is considered one of the seven names of God in Judaism and a form of God's name in Christianity.

The consensus among scholars is that the historical vocalization of the Tetragrammaton at the time of the redaction of the Torah (6th century BCE) is most likely Yahweh. The historical vocalization was lost because in Second Temple Judaism, during the 3rd to 2nd centuries BCE, the pronunciation of the Tetragrammaton came to be avoided, being substituted with Adonai ('my Lord'). The Hebrew vowel points of Adonai were added to the Tetragrammaton by the Masoretes, and the resulting form was transliterated around the 12th century CE as Yehowah. The derived form Iehovah first appeared in the 16th century. The form Jehovah began to printed following a 17th-century development leading J to become a separate letter for printing the consonantal I.
