Eastern Orthodox Christians believe that Jesus of Nazareth is the promised Messiah of the Jews, the God of Israel come to be with His people, the Redeemer of the human race who saves the world from sin and its effects, the comprehensible self-revelation of the incomprehensible God, and the pre-eternal Son begotten of the Father before all ages: "the only-begotten Son of God, begotten of the Father before all worlds (æons), Light of Light, very God of very God, begotten, not made, being of one substance with the Father." He is said to have been begotten timelessly as God without a mother and begotten in history as man without a father.
