Hebrews 7:26-28
Heb 7:26 (KJB)
For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens;
Harmless - Without evil or blameless
Separate - To divide or depart
Higher - An adjective which modifies things like mountains
Here is another summary of the superiority of the priesthood of the Lord Jesus Christ. First of all He is holy which means He is totally sinless and devout. He is not mixed in any capacity with the world system. Then He is described as harmless which means He has absolutely no evil in Him whatsoever. The earthly priests were all sin laden because they were part of the human race and had the sin nature of Adam in them. Jesus was devoid of the sin nature when He was here because He was not born of an earthly father and therefore the sin nature was not passed on to Him. Next he is described as undefiled in that sin had no effect upon Him and that is why He did not have to make a sacrifice for sin first as the earthly priests did. He was of a pure nature and was totally unsullied. He is also described as separate from sinners which means He did not come from any earthly lineage. He is described as according to the eternal order of Melchisedec. He is separated from being born of a sinner but He is not separated to the point that He does not become involved in the lives of His Elect. As high as the heavens are, Christ is much higher. The Heavens in view here are the heavens we see such as the sun and stars. This means He has come from the third Heaven which is the abode of God.
Heb 7:27 (KJB)
Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people's: for this he did once, when he offered up himself.
The earthly priests because of their sin natures had to offer a sin offering on behalf of themselves before they could offer up a sacrifice for the supplicants. (Lev 16:6 KJV) And Aaron shall offer his bullock of the sin offering, which is for himself, and make an atonement for himself, and for his house. For Aaron and the Levitical priests to have their sacrifices accepted, first had to make atonement for themselves, so they would appear clean before the Lord. Then they would begin their service of offering sacrifices before the Lord. The sinless nature of the Lord Jesus excluded the need to offer any type of sacrifice for Himself because He did not need it. He knew no sin and yet became sin for us. (2 Cor 5:21 KJV) For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him. His own personal sacrifice upon Calvary was all that was needed to pay for the sins of His people and this He only needed to do once in contrast to the earthly priests which had to make atonement every day. Christ made atonement for the children of God and this resulted in them being made priests. (Rev 1:6 KJV) And hath made us kings and priests unto God and his Father; to him be glory and dominion for ever and ever. Amen. As a result when the believer prays for someone or witnesses to someone they do not have to make an atonement of any kind since they are in Christ and Christís sacrifice was totally effectual for the believer. So the priesthood of the believer is actually superior to the priesthood under the Mosaic law. Aaron had to make atonement for himself before he administered his office but the Lord Jesus Christ did not have to make any atonement for Himself. The believer being in Christ has all their sins forgiven and they need not do anything before they do any ministry. The Roman Catholic institution should heed this verse because Christ was only sacrificed once and they attempt to re-sacrifice Him hundreds of times daily in their Mass. This is an abomination unto the Lord and should be for every true Christian. The Roman Catholic is not my brother in the Lord unless they have become saved and then they can no longer remain in that institution.
Heb 7:28 (KJB)
For the law maketh men high priests which have infirmity; but the word of the oath, which was since the law, maketh the Son, who is consecrated for evermore.
Who is consecrated - Having been perfected or completed
Under the Mosaic law, the High Priest was taken from among men and, of course, these man had weaknesses because of the flesh. As each one completed their course, many of them had died and had to be replaced. This was not the case with the Lord Jesus Christ. God had sworn by Himself that His Son was going to be a High Priest forever because with His sacrifice He has perfected the final priesthood. The earthly High Priest was a temporary position but because Christ sits at the right hand of God, He is a High Priest of perfection without limits. The earthly priesthood had limits because of the flesh but the Lord Jesus because of His omniscience has full knowledge of the actions and thoughts of every one of His redeemed believers. His intercession on their behalf is based totally upon His one sacrifice and not many as earthly priests must endure.
