He is not the Pope; he is higher than any spiritual or civil authority. This priest is Jesus Christ. Under the old law of Moses there were twenty four divisions of the priesthood (1 Chronicles 24). They served in an earthly tabernacle (temple). Offering sacrifices that were but a shadow of the greater tabernacle that is now constructed without man’s hands, the former tabernacle had a curtain preventing people from viewing the most Holy of Holies. This hidden portion of the tabernacle was reserved exclusively for the high priest to offer blood sacrifices, animal sacrifices. All of the services performed by the priests were done under strict ordinances of the old Law of Moses. With a change in the law came a change in the priesthood (Hebrews 7:12). This superior priesthood has arrived exclusively for Christians. Consider the following passage from Hebrews.
(1) Now even a first covenant had ordinances of divine service, and its sanctuary, a sanctuary of this world. (2) For there was a tabernacle prepared, the first, wherein were the candlestick, and the table, and the showbread; which is called the Holy place. (3) And after the second veil, the tabernacle which is called the Holy of holies; (4) having a golden altar of incense, and the ark of the covenant overlaid round about with gold, wherein was a golden pot holding the manna, and Aaron’s rod that budded, and the tables of the covenant; (5) and above it cherubim of glory overshadowing the mercy-seat; of which things we cannot now speak severally. (6) Now these things having been thus prepared, the priests go in continually into the first tabernacle, accomplishing the services; (7) but into the second the high priest alone, once in the year, not without blood, which he offereth for himself, and for the errors of the people: (8) the Holy Spirit this signifying, that the way into the holy place hath not yet been made manifest, while the first tabernacle is yet standing; (9) which is a figure for the time present; according to which are offered both gifts and sacrifices that cannot, as touching the conscience, make the worshipper perfect, (10) being only (with meats and drinks and divers washings) carnal ordinances, imposed until a time of reformation. (11) But Christ having come a high priest of the good things to come, through the greater and more perfect tabernacle, not made with hands, that is to say, not of this creation, (12) nor yet through the blood of goats and calves, but through his own blood, entered in once for all into the holy place, having obtained eternal redemption. (13) For if the blood of goats and bulls, and the ashes of a heifer sprinkling them that have been defiled, sanctify unto the cleanness of the flesh: (14) how much more shall the blood of Christ, who through the eternal Spirit offered himself without blemish unto God, cleanse your conscience from dead works to serve the living God? Hebrews 9:1-14
Christians do not have to rely on any priestly order save the priesthood of Jesus Christ. We are called a royal priesthood ourselves in 1 Peter 2:9. Based upon the book of Hebrews, we may go directly to God in prayer without consulting the medium of any other priest than the one and only sacrificial Lamb of God. We can ask for the prayers of others’ supplication but we do not have to go through any other priest to access God’s mercy seat than Jesus. He is better than any earthly system. I do not have to enter a confessional booth and confess my sins to another human being. Jesus Christ is my personal advocate with God. “My little children, these things write I unto you that ye may not sin. And if any man sin, we have an Advocate with the Father, Jesus Christ the righteous: and he is the propitiation for our sins; and not for ours only, but also for the whole world.” 1 John 2:1-2. All Christians are priests in the order of the Messiah’s priesthood (Revelation 5:10).
“Let us therefore draw near with boldness unto the throne of grace, that we may receive mercy, and may find grace to help us in time of need.” Hebrews 4:16
