Jesus' baptism was the occasion at which His messiahship became obvious publicly. Matthew recorded this event as he did to convince his readers further of Jesus' messianic qualifications.
3:13-14 John hesitated to baptize Jesus because he believed that Jesus did not need to repent. John evidently suggested that it was more appropriate that Jesus baptize him than that he baptize Jesus because he knew that Jesus was more righteous than he was. It is unlikely that John meant that he wanted the Spirit and fire baptism of Jesus. John did not know that Jesus was the Messiah until after he had baptized Him (John 1:31-34).
3:15 John agreed to baptize Jesus only after Jesus convinced him that by baptizing Him both of them would "fulfill all righteousness."What did Jesus mean?
An important prerequisite to understanding Jesus' words is an understanding of the meaning of "righteousness."Matthew's use of this word is different from Paul's. Paul used it mainly to describe a right standing before God, positional righteousness. Matthew used it to describe conformity to God's will, ethical righteousness.165Ethical righteousness is the display of conduct in one's actions that is right in God's eyes. It does not deal with getting saved but responding to God's grace. In Matthew a righteous person is one who lives in harmony with the will of God (cf. 1:19). Ethical righteousness is a major theme of the Old Testament, and it was a matter that concerned the Jews in Jesus' day, especially the Pharisees.
Jesus understood that it was God's will for John to baptize Him. There is no Old Testament prophecy that states that Messiah would undergo water baptism, but there is prophecy that Messiah would submit Himself to God (Isa. 42:1; 53; et al.). That spirit of submissiveness to God's will is primarily what John's baptism identified in those who submitted to it. Consequently it was appropriate for Jesus to undergo John's baptism, and John consented to baptize Him. In doing so, Jesus authenticated John's ministry and identified Himself with the godly remnant within Israel.
"The King, because of His baptism, is now bound up with His subjects."166
"Jesus' baptism in the Jordan stands as a counterpart of Israel's crossing of the Red Sea at the onset of the Exodus. Thus Jesus transversed the Jordan and then, like Israel, spent a period of time in the wilderness. Jesus, another Moses, on whom the Spirit had been placed (Isa. 63:10-14), would lead the way."167
"Jesus fulfilled the Scripture by replicating in His own life the patterns of God's historical relations with Israel and by accomplishing in His own history the predicted events of prophecy."168
It is significant that Matthew did not describe Jesus' baptism. His emphasis was on the two revelatory events that followed it (cf. 2:1-23).
3:16-17 The Greek text stresses the fact that Jesus' departure from the water and God's attestation of Him as the Messiah occurred at the same time. The NIV translation gives this sense better than the NASB.
The person who saw the Spirit descending was evidently Jesus. Jesus is the person in the immediately preceding context. John the Evangelist recorded that John the Baptist also saw this (John 1:32), but evidently no one but Jesus heard the Father's voice. The phrase "the heavens were opened"or "heaven was opened"recalls instances of people receiving visions from God. In them they saw things unseen by other mortals (e.g., Isa. 64:1; Ezek. 1:1; cf. Acts 7:56; Rev. 4:1; 19:11). The phrase implies that new revelation will follow to and through Jesus. What Jesus saw was the Holy Spirit in the form of a dove, not in a dove-like fashion, descending on Him (cf. Luke 3:22). This is the first explicit identification of the Holy Spirit and a dove in Scripture. It was an appropriate symbol because of its beauty, heavenly origin, freedom, sensitivity, and peaceful nature.
"The descent of the Spirit upon Jesus denotes the divine act whereby God empowers him to accomplish the messianic ministry he is shortly to begin (4:17). Such empowerment, of course, is not to be construed as Jesus' initial endowment with the Spirit, for he was conceived by the Spirit. Instead, it specifies in what way Jesus proves to be the mightier One John had said he would be (3:11). It also serves as the reference point for understanding the authority' with which Jesus discharges his public ministry. Empowered by God's Spirit, Jesus speaks as the mouthpiece of God (7:28-29) and acts as the instrument of God (12:28)."169
In Isaiah 42:1 the prophet predicted that God would put His Spirit on His Servant. That happened at Jesus' baptism. Matthew's account shows fulfillment though the writer did not draw attention to it as such here. When God's Spirit came on individuals in the Old Testament, He empowered them for divine service. That was evidently the purpose of Jesus' anointing as well (Luke 4:14; 5:17; cf. Luke 24:49).
An audible revelation followed the visual one (v. 17). The voice from heaven could be none other than God's. After 400 years without prophetic revelation, God broke the silence. He spoke from heaven to humankind again. Matthew recorded God's words as a general announcement (cf. 17:5). The other evangelists wrote that God said, "You are my beloved Son"(Mark 1:11; Luke 3:22). Evidently the accounts in Mark and Luke contain the actual words God used, the ipisissima verba, whereas Matthew gave a free quotation of God's words, the ipisissima vox.170Matthew did so because he used what happened at Jesus' baptism as evidence of His messiahship.
"Had the crowds heard the voice from heaven, it is inexplicable why one segment of the public does not at least entertain the idea that Jesus is the Son of God. And had John heard the voice from heaven, it is odd that his question of 11:2-3 contains no hint of this. On the contrary, it reflects the selfsame view of Jesus that John had expressed prior to the baptism, namely, that Jesus is the Coming One (3:11-12)."171
The words God spoke identified Jesus as the Messiah promised in the Old Testament. The term "Son of God"was one that God used of David's descendant who would follow him on Israel's throne (2 Sam. 7:13-14; Ps. 2:7; 89:26-29; cf. Matt. 1:20; 2:15; 4:3, 6). God's commendation also linked Jesus with the Suffering Servant at the commencement of His ministry (Isa. 42:1; 53). The Beloved One is equivalent to the One with whom the Father was "well pleased"(Isa. 42:1). Genesis 22:2 may also be behind this announcement since that verse describes Isaac as Abraham's beloved only son. Consequently, Son of God is a messianic title.172Notice the involvement of all three members of the Trinity in Jesus' baptism. This indicates its importance.
In this one statement at the beginning of Jesus' ministry, God presented Him as the Davidic Messiah, the Son of God, the representative of the people, and the Suffering Servant. Matthew had presented Jesus in all of these roles previously, but now God the Father confirmed His identity.
". . . God's baptismal declaration at 3:17 reveals itself to be climactic within the context of 1:1-4:16 because this is the place where God's understanding of Jesus as his Son ceases to be of the nature of private information available only to the reader and becomes instead an element within the story that henceforth influences the shape of events."173
"Because Matthew so constructs his story that God's evaluative point of view is normative, the reader knows that in hearing God enunciate his understanding of Jesus, he or she has heard the normative understanding of Jesus, the one in terms of which all other understandings are to be judged. In Matthew's story, God himself dictates that Jesus is preeminently the Son of God."174
"He did not becomeSon of God at His baptism, as certain heretical teachers in the early Church maintained; but it was then that He was appointed to a work which He alone could perform, because of His unique relationship with His Father."175
Matthew passed over all the incidents of Jesus' childhood, including His appearance at the temple (Luke 2:41-50), because his interests were selective and apologetic rather than merely historical. He introduced Jesus as the messianic King of Israel who fulfilled Old Testament prophecy and received divine confirmation from God with an audible word from heaven (cf. Exod. 20:1).176
In chapter 1 Matthew stressed the glories of Messiah's person. In chapter 2 he gave a preview of the reception He would receive as Israel's Messiah. In chapter 3 he introduced the beginning of His ministry with accounts of His earthly forerunner's heralding and His heavenly Father's approbation.
