I am Torah observant but believe that Jesus of Nazareth (Jesus Christ) was the biblical Messiah. Can I be a Karaite Jew?
Anyone who believes in Jesus, Yeshua, Yahshua, or the man from Nazareth by any other name, invariably gets his information about this person from the collection of writings commonly known as the New Testament. Karaites by definition only believe in the Tanach and therefore someone who believes in Jesus could not be a Karaite.
