But it is also necessary for everlasting salvation that one faithfully believe the incarnation of our Lord Jesus Christ. Therefore, it is the right faith that we believe and confess that our Lord Jesus Christ, the Son of God, is at the same time both God and man. He is God, begotten from the substance of the Father before all ages; and He is man, born from the substance of His mother in this age: perfect God and perfect man, composed of a rational soul and human flesh; equal to the Father with respect to His divinity, less than the Father with respect to His humanity. Although He is God and man, He is not two, but one Christ: one, however, not by the conversion of the divinity into flesh, but by the assumption of the humanity into God; one altogether, not by confusion of substance, but by unity of person. For as the rational soul and flesh is one man, so God and man is one Christ, who suffered for our salvation, descended into hell, rose again the third day from the dead, ascended into heaven, and is seated at the right hand of the Father, God Almighty, from whence He will come to judge the living and the dead. At His coming all people will rise again with their bodies and give an account concerning their own deeds. And those who have done good will enter into eternal life, and those who have done evil into eternal fire. (excerpt from The Athanasian Creed)

Here we glorify the Lord Jesus Christ. All truth claims of the Christian faith rest upon the person of Jesus.  His incarnation, birth, life, baptism, crucifixion, death, burial, resurrection, and second coming are the facts upon which our faith lives and breathes. There are other truth claims of the faith that are vital to believers. But all of those truths are illuminated by the light of His glory. Without Christ and His resurrection our faith would be vain, empty.
