righteousness." Jesus' baptism and anointing marked the beginning of His official priestly ministry on earth for His church. As their High Priest, Jesus identified Himself with His sinful people. He became Sin-bearer for all His people's sins from the beginning of His official ministry (His baptism), to its end (His death on the cross).
To be officially consecrated as a priest, Jesus had to perfectly fulfill all the righteous demands of the law regarding priestly ordination. To be officially ordained as a priest, a person had to meet the following three requirements.
a. A priest had to be thirty years of age (Numbers 4:3, 47). Therefore in the verse following the report of His baptism, the Gospel of Luke states that Jesus was thirty years of age (Luke 3:23).
b. A priest had to be called of God to serve (Exodus 28:1). Therefore the Book of Hebrews emphasizes Jesus' calling by God to a higher, a kingly priesthood after the order of Melchizedek (Hebrews 5:4-6).
c. A priest had to be sprinkled or anointed with:
-Water: "And Aaron and his sons thou shalt bring unto the door of the tabernacle of the congregation, and shalt wash them with water" (Exodus 29:4). "And thus shalt thou do unto them, to cleanse them: Sprinkle water of purifying upon them"(Numbers 8:7a).
-Oil: "Then shalt thou take the anointing oil, and pour it upon his head, and anoint him" (the High Priest, Exodus 29:7). Oil is a type of the Holy Spirit throughout Scripture.
-Blood: "And thou shalt take of the blood that is upon the altar, and of the anointing oil, and sprinkle it upon Aaron, and upon his garments, and upon his sons, and upon the garments of his sons with him: and he shall be hallowed, and his garments, and his sons' garments with him"
And Jesus Himself began to be about thirty years of age, being (as was supposed) the son of Joseph, which was the son of Heli.
And no man taketh this honour unto himself, but he that is called of God, as was Aaron.
So also Christ glorified not Himself to be made an high priest; but He that said unto Him, Thou an My beloved Son, today have I begotten Thee.
As He saith also in another place, Thou an a priest for ever after the order of Melchizedek.
After exercising His priestly uthority and cleansing the temple, the chief priests, scribes,
and elders approach Him:
And say unto Him, By what authority doest Thou these things? and who gave Thee this authority to do these things?
And Jesus answered and said unto them, I will also ask of you one question, and answer Me, and I will tell you by what authority I do these things.
The baptism of John, was it from heaven, or of men? answer Me.
When His priestly authority was questioned, why did Jesus refer them to the baptism of John?
