To Fulfill All Righteousness
John the Baptist’s ministry was one of preparation. He called Israel to repentance and baptized those who confessed their sins in anticipation of the coming Messiah. Matthew 3:11 (ESV): “I baptize you with water for repentance, but he who is coming after me is mightier than I… He will baptize you with the Holy Spirit and fire“. Notice that Scripture distinguishes between two baptisms.
- John’s baptism with water, administered as a baptism of repentance.
- Christ’s baptism with the Holy Spirit, whereby Jesus baptizes believers into the new covenant.
These are related but distinct ministries.
When Jesus Himself came to John to be baptized, John’s immediate reaction reveals that something unusual was taking place. Matthew 3:13–14 (ESV): “Then Jesus came from Galilee to the Jordan to John, to be baptized by him. John would have prevented Him, saying, ‘I need to be baptized by You, and do You come to me?‘”. John understood that Jesus had no sins to confess. Unlike every other person John baptized, Jesus had been conceived by the Holy Spirit, was born without Adam’s sinful corruption, and throughout His earthly life never committed sin (Hebrews 4:15; 1 Peter 2:22). Consequently, Jesus had no need to undergo a baptism of repentance. John therefore questioned why Jesus would seek baptism at all.
Jesus answered with these remarkable words: Matthew 3:15 (ESV): “Let it be so now, for thus it is fitting for us to fulfill all righteousness“. This raises an important question. If Jesus was sinless, and His baptism was not for repentance, what righteousness was He fulfilling?
Fulfilling Every Requirement of the Law
The answer lies in Jesus’ relationship to the Law. Jesus repeatedly taught that He had not come to abolish the Law but to fulfill it, Matthew 5:17–18. Likewise, Paul reminds us that “the law is holy, and the commandment holy and righteous and good“, (Romans 7:12). Jesus did not come to bypass God’s requirements. He came to satisfy every one of them.
- Every prophecy.
- Every ordinance.
- Every ceremonial requirement.
- Every “jot and tittle.”
If Christ were to become our perfect High Priest, then He would willingly submit to every lawful requirement that God Himself had established.
The Priestly Consecration
Under the Mosaic Law, the High Priest did not simply begin serving by appointment alone. He first underwent a formal consecration prescribed by God. Among other things, this included:
- preparation and instruction,
- anointing,
- ceremonial washing,
- and public consecration before beginning priestly ministry.
These requirements can be seen throughout Exodus 29 and Leviticus 8 and 16. Jesus fulfilled each of these requirements. His public ministry begins at approximately thirty years of age (Luke 3:23), corresponding to the traditional age at which priests entered service. Immediately after His baptism,
- the Holy Spirit descends upon Him,
- the Father publicly declares His approval,
- and Christ begins His public priestly ministry.
None of these events are accidental. They form the inauguration of the true High Priest.
Why Baptism?
This is where the meaning of baptism becomes important. The Greek word βαπτίζω (baptizō) certainly includes Christian baptism and John’s baptism of repentance. However, its broader usage also includes ceremonial washing and ritual cleansing. Strong’s Concordance defines it as: “to make fully wet… ceremonial ablution… baptize… wash”. Likewise, Thayer defines it as:
- to immerse,
- to wash,
- to cleanse with water.
Jesus therefore was not undergoing John’s baptism because He needed repentance. Rather, He was submitting to the ceremonial washing required of the priesthood in order to fulfill every righteous requirement of God’s Law. His baptism was therefore not an admission of sin. It was an act of perfect obedience. He submitted to the Law He Himself had given so that He might fulfill it completely. In this sense, Christ’s baptism was one more step in fulfilling “all righteousness.”
Christ’s baptism was not an isolated event. It was the beginning of a carefully ordered sequence by which every legal, ceremonial, and prophetic requirement necessary for His priesthood would be fulfilled. If Jesus submitted to baptism in order to fulfill all righteousness, then we should expect to find the remainder of His earthly ministry marked by the same unwavering obedience to every requirement of God’s Law. That is precisely what we find.
From His baptism and anointing by the Holy Spirit, to His presentation as the spotless sacrifice upon the cross, and finally to His entrance into the heavenly sanctuary as our Great High Priest, every step unfolded according to the divine pattern established centuries earlier in the Law of Moses.
None of these events occurred by accident. Each formed part of God’s sovereign plan to demonstrate that Christ did not abolish the Law by ignoring its requirements, but fulfilled it by satisfying every one of them. The events surrounding Caiaphas, Christ’s seamless garment, the transfer of the priesthood, and His ministry after the order of Melchizedek are not isolated incidents. Rather, they are successive pieces of a single legal and theological framework that culminates with Christ presenting His own blood before the Father in the heavenly tabernacle.
The High Priesthood Could Not Be Shared
One detail is often overlooked when considering Christ’s crucifixion. At the time of Jesus’ arrest, Caiaphas was still serving as Israel’s High Priest. According to God’s Law, there could not simultaneously exist two lawful High Priests ministering before Him. Before Christ could begin His priestly ministry, the existing high priesthood had to come to its proper conclusion. Immediately following His arrest, Jesus was brought before Caiaphas for trial. During the proceedings, Caiaphas became enraged at Jesus’ testimony. Matthew 26:65 (ESV): “Then the high priest tore his robes and said, ‘He has uttered blasphemy!‘”
To many readers this appears to be little more than an emotional outburst. Yet under the Law it carried far greater significance. God had specifically commanded that the High Priest was not to tear his priestly garments, Leviticus 21:10. This was not merely wise advice or ceremonial tradition. It was a direct command given by God governing the office of the High Priest. By tearing his garments, Caiaphas violated the very law that regulated his priesthood. Whether Caiaphas understood the significance of his actions is beside the point. God certainly did. The One who established the Law also understood every legal implication contained within it.
The Untorn Garment of Christ
In remarkable contrast to Caiaphas, Scripture carefully records another garment, John 19:23–24. The Roman soldiers divided Jesus’ outer garments among themselves. Yet when they came to His seamless tunic, they deliberately refused to tear it. Instead they cast lots for it. John immediately tells us this fulfilled the prophecy of Psalm 22:18. That is certainly true. Yet it also serves another purpose.
Throughout His trial, crucifixion, resurrection, and ascension, Christ remained the perfect and undefiled High Priest. Unlike Caiaphas, whose priesthood had been compromised by violating God’s command, Christ’s priestly garments remained whole. The contrast could hardly be more striking.
One high priest tears his garments.
The other does not.
One disqualifies himself through disobedience.
The other fulfills every righteous requirement of the Law through perfect obedience.
A Change in the Priesthood
These events prepare us for one of the central teachings of Hebrews. “For when there is a change in the priesthood, there is necessarily a change in the law as well” (Hebrews 7:12). The writer of Hebrews explains that Christ did not become High Priest according to the Levitical order.
Instead, He became High Priest according to the order of Melchizedek. This was not an abandonment of God’s Law. Rather, it was its fulfillment. The Levitical priesthood had served its appointed purpose, pointing forward to the coming Messiah. Once Christ fulfilled every requirement of that priesthood and offered Himself as the once-for-all sacrifice, the temporary system gave way to the eternal priesthood it had foreshadowed from the beginning.
The Final Priestly Ministry
Although Christ declared upon the cross, “It is finished“, His priestly ministry was not yet complete. The sacrifice had been made. It still had to be presented. This explains why Scripture later describes Christ entering the heavenly sanctuary as our Great High Priest, Hebrews 9:11–12. Just as the earthly high priest entered the Holy of Holies carrying sacrificial blood before God, so Christ entered the greater and more perfect tabernacle—not with the blood of bulls and goats, but with His own blood—obtaining eternal redemption for His people.
This also sheds light on Jesus’ words to Mary Magdalene following His resurrection, John 20:17. His work upon the cross had been completed, yet His priestly presentation before the Father still remained. Only after fulfilling every aspect of His priestly ministry could Christ sit down at the right hand of the Majesty on high, having forever accomplished the redemption that the Levitical priesthood could only foreshadow.
