God the Father from ancient times anointed certain ones to specifically serve Him. Prepared oil was applied as an ointment to the head or body during the appointment ceremony (example, Ex. 30:22-30). The anointed one was called a "messiah". The anointing was typical of the anointing of the Holy Spirit.
Three types of servants became anointed. They were prophets, priests and kings. Prophets were God's representatives to make known God's ways, often to speak of things tomorrow as if they were today. Priests served in functions, such as gifts and sacrifices, teaching, and representing man before God. A king was a civil servant over the kingdom for purposes of obedience and protection.
By the time of the birth of Jesus, all three types had sometimes lacked God's approved standard. People had need of, and prophets had anticipated, one true messiah to come. He was to gather together the faithful. Some looked for an anointed prophet, some an anointed priest, and others an anointed king. God the Father sent His only begotten Son - Jesus. He sent Him, not as an anointed, but the anointed. He is the anointed prophet, the anointed priest and the anointed king, all three in one. He is the Hebrew Messiah, the Greek Christos, and the English Christ.
The Kingdom and it's prophet: "Moses, which said unto the children of Israel, a prophet shall the Lord your God raise up unto you of your brethren, like unto me: him shall ye hear" (Acts 7:37). Jesus was to have become a raised up (resurrected) anointed prophet.
"God ... hath in these last days spoken unto us by his Son ... " (Heb. 1:1-3). The Son's "hath ... spoken" words are for these last days, and not for some future Millennial dispensation. His law is perfect (Jas. 1:25; 2 Tim. 3:17).
"This is my beloved Son, in whom I am well pleased, hear ye Him" (Matt. 17:5)." ... they that hear shall live" (John 5:25)." ... earnestly contend for the faith which was once delivered unto the saints" (Jude 3). Jesus is the unique, resurrected, anointed prophet. He is Christ.
The kingdom and its priest: Early in the history of man's estrangement from God, "By faith Abel offered unto God a more excellent sacrifice than Cain... "(Gen. 4:8; Heb. 11:4). Later, heads of families (patriarchs) offered sacrifices to God for themselves and their clans. Noah came from the ark, "And Noah builded an altar unto the Lord" (Gen. 8:20). "At Sichem unto the plain of Moreh ... Abram ... there builded an altar unto the Lord ... " (Gen. 12:6,7).
Abram returned from the slaughter of king Chedorlaomer, bringing Lot, his family, and spoils from victory. "Melchizedek, king of Salem, brought forth bread and wine: and he was the priest of the most high God." Abram saw his greatness, "And he gave him tithes of all" (Gen. 14:18-20). This is the early mention of a priest of God.
The children of Israel were delivered from oppression and journeyed to Mt. Sinai. Moses was the leader and prophet, while Aaron was Moses' mouthpiece. Aaron and his sons were chosen to minister before God in the priest's office in Israel (Ex. 28:1).
"The Lord hath sworn, and will not repent, Thou art a priest for ever after the order of Melchizedek" (Psa. 110:4). This prophetic statement of David was spoken centuries before the birth of Jesus. Aaron's priesthood would cease and another priesthood would replace it. That prophecy was fulfilled when Jesus ascended on high. The whole Hebrews chapter seven teaches on these truths. Jesus became anointed as our faithful high priest. The law, based upon Aaron's priesthood, had ceased. It was blotted out and nailed to the cross (Col. 2:14). The new Testament, based upon the priesthood of Christ, came into effect (Heb. 7:11,12). To attempt to bind any portion of the law is to attempt to remove our own heavenly High Priest and to return to Aaron for sacrifices of bulls and goats.
The kingdom and its king: John preceded Jesus, preaching, "Repent ye: for the kingdom of heaven is at hand" (Matt. 3:2). Jesus taught in His prayer, " ... thy kingdom come ... " (Matt. 6:10).
A colorful description had been given by the psalmist, leading to Christ's entrance into heaven itself to receive His coronation as king. The prophecy began: "Lift up your heads, O ye gates; and be ye lifted up, ye everlasting doors; and the King of glory shall come in" (Psa. 24:7). This was fulfilled on the day of Pentecost. The Word states, "... God hath made that same Jesus, whom ye have crucified, both Lord and Christ" (Acts 2:36). Lord means ruler, and Christ means the anointed (prophet, priest and king).
Conclusion: Modern premillennialists attempt to prove (?) Jesus Christ will come to earth for a literal thousand years as reigning king. Let's notice the consequences. Jesus could not teach one single new word as a prophet. Already, "God ... hath in these last days spoken unto us by his Son ... " (Heb. 1:1,2).
Jesus could not offer one single sacrifice, or plead one single case before God's throne from earth; seeing, "For if he were on earth, he should not be a priest ... " (Heb. 8:4).
Jesus could not rule as king from Jerusalem as a descendant of Coniah (Jeconiah). Jesus was listed as the offspring of David, through Coniah (Matt. 1:11, 12). Coniah was the last king ordained of God to rule God's people from Jerusalem. Jeremiah the prophet wrote of Coniah, "... Write ye this man childless, a man that shall not prosper in his days: for no man of his seed shall prosper, sitting upon the throne of David, and ruling any more in Judah" (Jer. 22:28-30). There shall be no other God-sanctioned earthly king, and that would include Jesus the seed of Coniah. Jesus is a heavenly king. Now!
God moved the tongue of His prophet Hosea to exclaim to His people, "1 gave thee a king in mine anger, and took him away in my wrath" (Hos. 13:11). That's the lock on any futuristic king's door!
On earth, Premillennialists to the contrary notwithstanding, it is exactly impossible for Jesus to be a future anointed prophet, anointed priest, or anointed king. Empty is any theory which would attempt to bring our Christ down! Lest we forget!
