Jehovah’s Witnesses are not always accepted by traditional Christian religions. They arose from a Bible study group in the late 19th century guided by a gentleman called Charles Russell. Like many religious groups of that period, they were dissatisfied with the old time religion that seemed to have failed and looked forward to a new beginning in the millennial return of Jesus Christ to the earth. Their movement is best categorized as a restoration movement in Christianity.
They claim exclusivity in correctness of doctrine and practice. They are tightly controlled doctrinally by a small group of men based in Brooklyn, New York. They believe in only one God, and that his name is Jehovah.
They believe that the Earth was created by God in a perfect state known as the Garden of Eden and when Adam and Eve sinned, they destroyed the world God made, bringing in evil and making it necessary for Jesus, the son of God, to pay a ransom to save mankind. They believe that when God returns to the earth to rule in righteousness, that the earth will be restored to its paradisiacal glory, and that it will be like the Garden of Eden was meant to be from the beginning.
Taking pride that they are not part of the larger Christian community, they proselyte and share with others why their beliefs are more correct.
Their rejection of the Trinity creed and their concept of Jesus being the Son of God, but not God, is where they receive many accusations that they are not authentic Christians. They believe that their translation of the Bible, called the New World Translation, is the most correct, and that their interpretation of the scripture is the most correct in the world today.
