In Leviticus chapter eight, verse two describes the ordination of Aaron and his sons to the priesthood. In the Old Testament, the worshiper who approached God needed not only an offering but also the mediation of a priest. The Leviticus priesthood described here finds fulfillment in Jesus Christ, the believer’s high priest. A priest appoints on behalf of the people as a mediator between God and humans. His purpose was to help men and women draw near to God and to bring them to forgiveness and salvation. The priest brought people to God by offering gifts, sacrifices for sin, and teaching the law of God.
Under the new covenant, the priestly ministry is among the ministry gifts of believers. Jesus Christ is now the high priest of the new covenant, replacing the imperfect Old Testament priesthood. He is the perfect priest “forever.” Jesus Christ is the mediator between God and humans. The Son of God brings the gift of salvation for sinners to those who accept Him. The sacrifices of sins Jesus Christ bore on the cross enable the opportunity for a personal relationship with Him. The teaching of the law is in His Word, the Holy Scriptures: The Holy Bible.
Aaron is known for being the first of the Levitical, or Aaronic, priesthood. Aaron, the older brother of Moses, was responsible for the people when Moses went up to the mountain to meet with God. However, the people of Israel grew restless, waiting for Aaron’s younger brother to come down. The Israelites decide to make a molten calf, and Aaron succumbs to their wishes. The priest is to instill godly principles among the congregation and direct their path to God. Not to compromise and give in to ungodly suggestions and participate in them, which Aaron did in this case.
