A method of criticizing the Christianity in the biographies of Jesus has been popular since the 19th century.It’s mostly because the Christian doctrine about Incarnation emphasizes that there are both divinity and humanity in Jesus.The biographies of Jesus target on the Incarnation directly
and negate the possibility entirely that Jesus is the Son of God.The biographies of Jesus are provided with the functions of criticism to the Christianity because they change God into a person.But the writers of the biographies have the different negative attitude to Jesus who is the incarnation of God in respect that they are in the different social condition and the different position of the religion.
