This is all we know
about Melchizedek

Genesis 14:18-20
Then Melchizedek, king of Salem, brought out bread and wine; he was a priest to Yahweh. He blessed him and said: "Abram is blessed by God Most High, Creator of heaven and earth, and I give praise to God Most High who has handed over your enemies to you." And Abram gave him a tenth of everything.

Psalm 110:4
Yahweh has sworn an oath and will not take it back: "Forever, You are a priest like Melchizedek."

Hebrews 5 - 10:18
For every high priest taken from men is appointed in service to God for the people, to offer both gifts and sacrifices for sins. He is able to deal gently with those who are ignorant and are going astray, since he is also subject to weakness. Because of this, he must make a sin offering for himself as well as for the people. No one takes this honor on himself; instead, a person is called by God, just as Aaron was. In the same way, the Messiah did not exalt Himself to become a high priest, but the One who said to Him, You are My Son; today I have become Your Father, also said in another passage, You are a priest forever in the order of Melchizedek. During His earthly life, He offered prayers and appeals with loud cries and tears to the One who was able to save Him from death, and He was heard because of His reverence. Though He was God’s Son, He learned obedience through what He suffered. After He was perfected, He became the source of eternal salvation for all who obey Him, and He was declared by God a high priest in the order of Melchizedek. We have a great deal to say about this, and it’s difficult to explain, since you have become too lazy to understand. Although by this time you ought to be teachers, you need someone to teach you the basic principles of God’s revelation again. You need milk, not solid food. Now everyone who lives on milk is inexperienced with the message about righteousness, because he is an infant. But solid food is for the mature—for those whose senses have been trained to distinguish between good and evil. Therefore, leaving the elementary message about the Messiah, let us go on to maturity, not laying again the foundation of repentance from dead works, faith in God, teaching about ritual washings, laying on of hands, the resurrection of the dead, and eternal judgment. And we will do this if God permits. For it is impossible to renew to repentance those who were once enlightened, who tasted the heavenly gift, became companions with the Holy Spirit, tasted God’s good word and the powers of the coming age, and who have fallen away, because, to their own harm, they are recrucifying the Son of God and holding Him up to contempt. For ground that has drunk the rain that has often fallen on it and that produces vegetation useful to those it is cultivated for receives a blessing from God. But if it produces thorns and thistles, it is worthless and about to be cursed, and will be burned at the end. Even though we are speaking this way, dear friends, in your case we are confident of the better things connected with salvation. For God is not unjust; He will not forget your work and the love you showed for His name when you served the saints—and you continue to serve them. Now we want each of you to demonstrate the same diligence for the final realization of your hope, so that you won’t become lazy but will be imitators of those who inherit the promises through faith and perseverance. For when God made a promise to Abraham, since He had no one greater to swear by, He swore by Himself: I will indeed bless you, and I will greatly multiply you. And so, after waiting patiently, Abraham obtained the promise. For men swear by something greater than themselves, and for them a confirming oath ends every dispute. Because God wanted to show His unchangeable purpose even more clearly to the heirs of the promise, He guaranteed it with an oath, so that through two unchangeable things, in which it is impossible for God to lie, we who have fled for refuge might have strong encouragement to seize the hope set before us. We have this hope as an anchor for our lives, safe and secure. It enters the inner sanctuary behind the curtain. Jesus has entered there on our behalf as a forerunner, because He has become a high priest forever in the order of Melchizedek. For this Melchizedek—King of Salem, priest of the Most High God, who met Abraham and blessed him as he returned from defeating the kings, and Abraham gave him a tenth of everything; first, his name means king of righteousness, then also, king of Salem, meaning king of peace; without father, mother, or genealogy, having neither beginning of days nor end of life, but resembling the Son of God—remains a priest forever. Now consider how great this man was—even Abraham the patriarch gave a tenth of the plunder to him! The sons of Levi who receive the priestly office have a command according to the law to collect a tenth from the people—that is, from their brothers—though they have also descended from Abraham. But one without this lineage collected tenths from Abraham and blessed the one who had the promises. Without a doubt, the inferior is blessed by the superior. In the one case, men who will die receive tenths, but in the other case, Scripture testifies that he lives. And in a sense Levi himself, who receives tenths, has paid tenths through Abraham, for he was still within his ancestor when Melchizedek met him. If then, perfection came through the Levitical priesthood (for under it the people received the law), what further need was there for another priest to appear, said to be in the order of Melchizedek and not in the order of Aaron? For when there is a change of the priesthood, there must be a change of law as well. For the One these things are spoken about belonged to a different tribe. No one from it has served at the altar. Now it is evident that our Lord came from Judah, and Moses said nothing about that tribe concerning priests. And this becomes clearer if another priest like Melchizedek appears, who did not become a priest based on a legal command concerning physical descent but based on the power of an indestructible life. For it has been testified: You are a priest forever in the order of Melchizedek. So the previous command is annulled because it was weak and unprofitable (for the law perfected nothing), but a better hope is introduced, through which we draw near to God. None of this happened without an oath. For others became priests without an oath, but He became a priest with an oath made by the One who said to Him: The Lord has sworn, and He will not change His mind, You are a priest forever. So Jesus has also become the guarantee of a better covenant. Now many have become Levitical priests, since they are prevented by death from remaining in office. But because He remains forever, He holds His priesthood permanently. Therefore, He is always able to save those who come to God through Him, since He always lives to intercede for them. For this is the kind of high priest we need: holy, innocent, undefiled, separated from sinners, and exalted above the heavens. He doesn’t need to offer sacrifices every day, as high priests do—first for their own sins, then for those of the people. He did this once for all when He offered Himself. For the law appoints as high priests men who are weak, but the promise of the oath, which came after the law, appoints a Son, who has been perfected forever. Now the main point of what is being said is this: We have this kind of high priest, who sat down at the right hand of the throne of the Majesty in the heavens, a minister of the sanctuary and the true tabernacle that was set up by the Lord and not man. For every high priest is appointed to offer gifts and sacrifices; therefore it was necessary for this priest also to have something to offer. Now if He were on earth, He wouldn’t be a priest, since there are those offering the gifts prescribed by the law. These serve as a copy and shadow of the heavenly things, as Moses was warned when he was about to complete the tabernacle. For God said, Be careful that you make everything according to the pattern that was shown to you on the mountain. But Jesus has now obtained a superior ministry, and to that degree He is the mediator of a better covenant, which has been legally enacted on better promises. For if that first covenant had been faultless, there would have been no occasion for a second one. But finding fault with His people, He says: Look, the days are coming, says the Lord, when I will make a new covenant with the house of Israel and with the house of Judah—not like the covenant that I made with their ancestors on the day I took them by their hands to lead them out of the land of Egypt. I disregarded them, says the Lord, because they did not continue in My covenant. But this is the covenant that I will make with the house of Israel after those days, says the Lord: I will put My laws into their minds and write them on their hearts. I will be their God, and they will be My people. And each person will not teach his fellow citizen, and each his brother, saying, “Know the Lord,” because they will all know Me, from the least to the greatest of them. For I will be merciful to their wrongdoing, and I will never again remember their sins. By saying, a new covenant, He has declared that the first is old. And what is old and aging is about to disappear. Now the first covenant also had regulations for ministry and an earthly sanctuary. For a tabernacle was set up, and in the first room, which is called the holy place, were the lampstand, the table, and the presentation loaves. Behind the second curtain, the tabernacle was called the most holy place. It contained the gold altar of incense and the ark of the covenant, covered with gold on all sides, in which there was a gold jar containing the manna, Aaron’s staff that budded, and the tablets of the covenant. The cherubim of glory were above it overshadowing the mercy seat. It is not possible to speak about these things in detail right now. With these things set up this way, the priests enter the first room repeatedly, performing their ministry. But the high priest alone enters the second room, and he does that only once a year, and never without blood, which he offers for himself and for the sins of the people committed in ignorance. The Holy Spirit was making it clear that the way into the most holy place had not yet been disclosed while the first tabernacle was still standing. This is a symbol for the present time, during which gifts and sacrifices are offered that cannot perfect the worshiper’s conscience. They are physical regulations and only deal with food, drink, and various washings imposed until the time of restoration. But the Messiah has appeared, high priest of the good things that have come. In the greater and more perfect tabernacle not made with hands (that is, not of this creation), He entered the most holy place once for all, not by the blood of goats and calves, but by His own blood, having obtained eternal redemption. For if the blood of goats and bulls and the ashes of a young cow, sprinkling those who are defiled, sanctify for the purification of the flesh, how much more will the blood of the Messiah, who through the eternal Spirit offered Himself without blemish to God, cleanse our consciences from dead works to serve the living God? Therefore, He is the mediator of a new covenant, so that those who are called might receive the promise of the eternal inheritance, because a death has taken place for redemption from the transgressions committed under the first covenant. Where a will exists, the death of the one who made it must be established. For a will is valid only when people die, since it is never in force while the one who made it is living. That is why even the first covenant was inaugurated with blood. For when every command had been proclaimed by Moses to all the people according to the law, he took the blood of calves and goats, along with water, scarlet wool, and hyssop, and sprinkled the scroll itself and all the people, saying, This is the blood of the covenant that God has commanded for you. In the same way, he sprinkled the tabernacle and all the articles of worship with blood. According to the law almost everything is purified with blood, and without the shedding of blood there is no forgiveness. Therefore it was necessary for the copies of the things in the heavens to be purified with these sacrifices, but the heavenly things themselves to be purified with better sacrifices than these. For the Messiah did not enter a sanctuary made with hands (only a model of the true one) but into heaven itself, so that He might now appear in the presence of God for us. He did not do this to offer Himself many times, as the high priest enters the sanctuary yearly with the blood of another. Otherwise, He would have had to suffer many times since the foundation of the world. But now He has appeared one time, at the end of the ages, for the removal of sin by the sacrifice of Himself. And just as it is appointed for people to die once—and after this, judgment-so also the Messiah, having been offered once to bear the sins of many, will appear a second time, not to bear sin, but to bring salvation to those who are waiting for Him. Since the law has only a shadow of the good things to come, and not the actual form of those realities, it can never perfect the worshipers by the same sacrifices they continually offer year after year. Otherwise, wouldn’t they have stopped being offered, since the worshipers, once purified, would no longer have any consciousness of sins? But in the sacrifices there is a reminder of sins every year. For it is impossible for the blood of bulls and goats to take away sins. Therefore, as He was coming into the world, He said: You did not want sacrifice and offering, but You prepared a body for Me. You did not delight in whole burnt offerings and sin offerings. Then I said, “See—it is written about Me in the volume of the scroll—I have come to do Your will, God!” After He says above, You did not want or delight in sacrifices and offerings, whole burnt offerings and sin offerings (which are offered according to the law), He then says, See, I have come to do Your will. He takes away the first to establish the second. By this will of God, we have been sanctified through the offering of the body of Jesus Christ once and for all. Every priest stands day after day ministering and offering the same sacrifices time after time, which can never take away sins. But this man, after offering one sacrifice for sins forever, sat down at the right hand of God. He is now waiting until His enemies are made His footstool. For by one offering He has perfected forever those who are sanctified. The Holy Spirit also testifies to us about this. For after He says: This is the covenant I will make with them after those days, says the Lord: I will put My laws on their hearts and write them on their minds, He adds: I will never again remember their sins and their lawless acts. Now where there is forgiveness of these, there is no longer an offering for sin.

Elementary?

If the "laying on of hands" is "elementary" to the message of the Messiah, why is it so rarely observed in Christendom?
