Who is and was and is to come
1 ¶ For every high priest taken from among men is ordained for men in the things that appertain to God, that he may offer up gifts and sacrifices for sins:
2 Who can have compassion on them that are ignorant and that err: because he himself also is compassed with infirmity.
3 And therefore he ought, as for the people, so also for himself, to offer for sins.
4 Neither doth any man take the honour to himself, but he that is called by God, as Aaron was.
5 So Christ also did not glorify himself, that he might be made a high priest: but he that said unto him: Thou art my Son: this day have I begotten thee.
6 As he saith also in anotherplace: Thou art a priest for ever, according to theorder of Melchisedech.
7 Who in the days of his flesh, with a strong cry and tears, offering up prayers and supplications to him that was able to save him from death, was heard for his reverence.
8 And whereas indeed he was the Son of God, he learned obedience by the things which he suffered.
9 And being consummated, he became, to all that obey him, the cause of eternal salvation:
10 ¶ Called by God a high priest, according to the order of Melchisedech.
11 Of whom we have much to say and hard to be intelligibly uttered: because you are become weak to hear.
12 For whereas for the time you ought to be masters, you have need to be taught again what are the first elements of the words of God: and you are become such as have need of milk and not of strong meat.
13 For every one that is a partaker of milk is unskilful in the word of justice: for he is a little child.
14 But strong meat is for the perfect: for them who by custom have their senses exercised to the discerning of good and evil.
St. Paul explains this same thing with different wording in Philippians.
5 For let this mind be in you, which was also in Christ Jesus:
6 Who being in the form of God, thought it not robbery to be equal with God:
7 But emptied himself, taking the form of a servant, being made in the likeness of men, and in habit found as a man.
8 He humbled himself, becoming obedient unto death, even to the death of the cross.
9 For which cause, God also hath exalted him and hath given him a name which is above all names:
10 That in the name of Jesus every knee should bow, of those that are in heaven, on earth, and under the earth:
11 And that every tongue should confess that the Lord Jesus Christ is in the glory of God the Father.
This is crucial to our understanding of Christ's mission to save us. In the above "emptied" is kenosis in the Greek. Christ's kenosis (He Who is the Immortal Son of God and has always existed from before He created anything, His emptying out of Himself for us and to us) consists of "taking the form of a servant" at His incarnation of the Blessed Virgin Mary by the Holy Spirit, "being made in the likeness of men" extremely important -- His incarnation in the flesh, "in habit found as a man" this part explains phrases like "learned obedience". Jesus never had to learn anything for Himself since He is God and Omniscient - All Knowing. But He willed to be born and grow up and be taught by Joseph and Mary. Think about it, it was the Blessed Virgin who taught Him the Psalms that He was the Mediator for David to receive by inspiration of the Holy Spirit and record for us. In simple terms He taught David the Psalms and willed that Mary would teach Him on earth the same psalms, though, of course He knew them already. So all references to His learning and growing and being perfected are only those things that He willed to go through for two basic reasons for our sakes. Number two first: to show us what our attitude and efforts should be on His behalf as His ambassadors to the rest of mankind. He "learned" but is actually teaching us. Number one in importance: "being made in the likeness of men" extremely important -- His incarnation in the flesh. St. Athanasius Contra Mundum (against the world [opposing heresy]) addresses this when he explains that had Christ the Immortal Son of the Father in the Unity and Power of the Holy Spirit simply have erased Adam's sin then the natural debt we all inherited to die from that sin would have meant that all men would die forever and be lost since God doesn't lie and He pronounced that the separation of man from God due to sin would by the natural property of human nature make anything else impossible. In other words if God simply erased the sin He would have erased men as well thereby. Worst yet, St. Athanasius tells us, the devil would thereby have won that round. But what God did, the Son, Who because of His Divine substance/essence - nature cannot die, is to take upon himself the real human nature of all men subsumed from Mary -- and therefore of Adam (see the genealogies in St. Matthew's, Chapter 1, and St. Luke's, Chapter 3, Gospels; in St. Luke's Gospel all the way back to Adam). Since of Adam, then, of all men. Since He had and has that nature in total union with His divine nature, when he suffered and died (it is in this sense that St. Paul says "learned obedience") in our place as the ransom from death then we become sons and daughters by adoption unto real eternal life at the future Return of Christ and the General Resurrection of the flesh, each of us, our bodies reunited with our same soul and same spirit. Therefore death, which insured that God's law would be obeyed, was originally God's way to insure that man would not become a diabolic creature totally in bondage to the devil, incapable of being in union with the Holy God, Himself. Christ took death, merited by all men, upon Himself preserving what God had said to Adam and Eve"upon that day (of disobedience) you will die". Therefore, Christ's death, then becomes the ransom to bring us out of thralldom to the devil and into union with God in Christ. Christ's Resurrection then becomes the guarantor of our resurrection -- which will absolutely happen. This is a brief description of Christ's kenosis. Christ's kenosis is the weightiest subject in the whole Bible. Christ's obedience loosed the debt of Adam's disobedience as Mary's obedience undid the knot of Eve's disobedience (that last is from St. Irenaeus). A note of warning: those who retie the knot of Eve's disobedience and who bind themselves again in the debt of Adam's disobedience by returning to pagan religions, who profess atheism or agnosticism, who follow after the Antichrist or who walk not in God's commandments though they pretend to be Christ's, will certainly be resurrected, but to eternal undying destruction in the lake of fire with the devil and all the fallen angels and all of the demons. Only the saints will inherit paradise with the elect angels in this universe recreated by God at the second coming of Jesus Christ at the end of this age of grace.
