CHRISTOLOGY: all theology, all doctrine, all preaching should point to Him
"...the prism through which all light concerning God is reflected is Jesus Christ. This means that Christology is the beginning and the end, better, the starting point and summary, of all Christian thought. Christology is Paul's theme when he writes, "For it is the very God who said. 'Let light shine out of darkness,' who has shone in our hearts to give the light of the knowledge of the glory of God in the face of Christ." (2 Cor 4:6)... Christology is the subject of theology. More precisely put, Jesus Christ is the subject of theology.
We understand that God in any sense differentiated from Jesus Christ is unknowable. This needs to be affirmed from the start. John writes in the prologue to his Gospel, "No one has ever seen God; the only Son, who is in the bosom of the Father, he has made him known" (1:18). John repeats this idea forcefully in his first letter: "No one has ever seen God" (4:12)... Bible religion knows nothing about a God who can be found or made out from our side of things... Theology is unable to start in those places [first cause, ground of our being] because the picture of God that emerges from such beginnings is speculative...
A theology that is Christology before it is anything else is a theology from the bottom up. It begins with the ministry of Jesus in his own time and space, and it states that it is entirely agnostic concerning anything other than what he has given us to know of the essential attributes of God... we begin, therefore, Christologically, with a concrete historic figure who appeared on the stage of human history..." -Paul F.M. Zahl (A Short Systematic Theology)
The Shorter Catechism as expounded by John Flavel on the humiliation of Christ
Q. 27. Wherein did Christ’s humiliation consist?
A. Christ’s humiliation consisted in his being born, and that in a low condition, made under the law, undergoing the miseries of this life, the wrath of God, and the cursed death of the cross; in being buried, and continuing under the power of death for a time.
Q. 1. What doth Christ’s humbling of’ himself import?
A. His voluntariness in the deepest point of self-denial? Psalm 40:7. Then said I, Lo, I come; in the volume of the book it is written of me.
Q. 2. What was the first act of Christ’s humiliation?
A. His taking man’s nature on him, with all its sinless infirmities; Romans 8:3. God sending his own Son in the likeness of sinful flesh, and for sin condemned sin in the flesh.
Q. 3. What is the second part of his humiliation?
A. That mean life he lived in this world, which obscured his divine glory; Mark 6:3. Is not this the carpenter, the son of Mary?
Q. 4. What was the first thing in Christ’s life that humbled him?
A. The poverty of it; Matthew 7:20. And Jesus saith unto him, the foxes have holes, and the birds of the air have nests; but the Son of man hath not where to lay his head.
Q. 5. What was the second thing in his life that humbled him?
A. The temptations of Satan, to which he was subject; Matthew 4:1. Then was Jesus led up of the Spirit into the wilderness, to be tempted of the devil, and that for our sakes. Hebrews 2:17-18. Wherefore in all things it behoved him to be made like unto his brethren. For in that he himself hath suffered, being tempted, he is able to succour them that are tempted.
Q. 6. What was the third thing in Christ’s life that humbled him?
A. His subjection to the law; Galatians 1:4. But when the fulness of’ the time was come, God sent forth his Son, made of a woman, made tinder the law.
Q. 7. What was the fourth thing in Christ’s life that humbled him?
A. The revilings and contradictions of’ sinners; Hebrews 12:3. For consider him that endureth such contradiction of sinners against himself.
Q. 8. Wherein was Christ humbled in his death?
A. His death was painful and ignominious; Galatians 3:13. Christ bath redeemed us from the curse of the law, being made a curse for us: For it is written, cursed is every one that hangeth on a tree. Made a curse for us, and deserted in it; Matthew 27:46. And about the ninth hour, Jesus cried with a loud voice, saying, Eli, Eli, lama sabacthani; that is to say, My God, My God, why hast thou forsaken me?
Q. 9. What is the first inference from hence?
A. That lowliness and humility becomes Christ’s followers; Matthew 11:29. Take my yoke upon you, and learn of me, for I am meek and lowly in heart.
Q. 10. What is the second inference?
A. That Christ’s love to sinners is astonishingly great; 2 Corinthians 8:9. For ye know the grace of’ our Lord Jesus Christ, that though he was rich, yet for our sakes he became poor, that ye through his poverty might he made rich.
Q. 11. What is the third inference?
A. Christians should be ready to suffer for Christ; 1 Peter 4:1. Forasmuch as Christ hath suffered for us in the flesh, arm yourselves likewise with the same mind: fi)r he that hath suffered in the flesh hath ceased from sin.
Q. 12. What is the last inference?
A. That humiliation is the true way to exaltation; Matthew 23:12 And whosoever shall exalt himself, shall be abased; and lie that shall humble himself, shall be exalted.
