The healing of the deaf man with the speech impediment resulted in a confession of Jesus' greatness that fell short of identifying Him as God (7:37). The healing of the blind man was the incident that God used to open the disciples' eyes to the biblical messianic identity of Jesus that Peter articulated.
Mark further highlighted the cause and effect relationship between these last two events by structuring the pericopes similarly. First, he presented the circumstances (vv. 22, 27). Second, he described partial sight and understanding (vv. 23-24, 28). Third, he recorded the giving of sight and understanding (vv. 25, 29). Fourth, he noted Jesus' command to remain silent (vv. 26, 30).198
8:27-28 Jesus and his disciples continued traveling north from Bethsaida toward Caesarea Philippi that stood about 25 miles away. Jesus asked the question in verse 27 with a view to asking the second question in verse 29. The popular answers to Jesus' first question all reflect an inadequate view of Him. Perhaps few people believed that Jesus was the Messiah, so the disciples did not even mention that possibility.
8:29 Jesus stressed "you"when He asked this question. He wanted to know whom the disciples, in contrast to the multitudes, believed He was. Peter spoke for the disciples. The other disciples evidently agreed with his statement and made no objection. This is the first time in Mark that Peter acted as spokesman for the Twelve. Yet from this time on, Peter was the prominent representative of the other disciples.199
". . . Peter's name, Rock,' is ironic, for he thinks he is like a rock. He happens to be the opposite of what his nickname suggests, for he falls asleep and later falls apart under the incriminating remarks of a maid of the High Priest."200
"Christ"is the English transliteration of the Greek christosthat translates the Hebrew masiahmeaning "anointed one."Originally this Hebrew term had a broad meaning and included anyone anointed by God including priests, kings, and prophets. Later in the Old Testament it came to have the technical meaning of the divine Davidic king who would appear to deliver Israel and establish a worldwide kingdom (Ps. 110:1; Dan. 9:25-26). In Mark, Jesus rarely used this term Himself (cf. 9:41; 12:35; 13:21), and He never used it of Himself. Probably He avoided it because of its political connotations and the popular misunderstanding of it, but Jesus accepted the title when others applied it to Him (cf. 14:6-62; John 4:25-26).
". . . the title . . . was particularly fitted to express his true relation both to the OT and to the people of God. . . . the title, applied to Jesus, designates him as the true meaning and fulfillment of the long succession of Israel's anointed kings and priests, the King and Priest . . .; the Prophet anointed with the Spirit of God, who fulfills the long line of Israel's prophets, and the One in whom the life of the whole nation of Israel finds its fulfillment and meaning, in whom and for whose sake the people of Israel were, and the new Israel now is, the anointed people of God."201
The timing of this question in Jesus' ministry was very important. The disciples had believed that Jesus was the Messiah from the beginning of their contact with Him (John 1:41, 51). However their understanding of the Messiah then was the traditional one of their day, namely that of a political leader. The multitudes likewise failed to understand that Jesus was much more than that. The religious leaders where becoming increasingly antagonistic. The disciples were about to receive new revelation regarding Jesus that would have costly implications for them. Therefore it was necessary for them to confess Jesus' identity clearly and unmistakably now.
Why did Mark only record that Peter said, "You are the Messiah,"rather than his complete statement, "You are the Messiah, the Son of the living God"(Matt. 16:16)? Mark's emphasis throughout his Gospel was on Jesus' humanity, as we have seen. By omitting the last part of Peter's statement, Mark did not mean that Peter failed to acknowledge Jesus' deity. This is precisely what Peter was confessing. However in Mark the term Messiah includes the concept of deity, as it does in the Old Testament. When the disciples said they had found the Messiah before Jesus called them to be His disciples, they used the title in the popular way (John 1:41, 51). Mark did not record those statements. He presented the disciples using the term "Messiah"in its true biblical meaning for his Gentile readers.
"For the Christians of Rome who read Mark, the confession You are the Messiah' was precisely their profession of faith . . ."202
Peter's confession constitutes a high-water mark in the disciples' understanding of and commitment to Jesus. They still had much to learn about the significance of Jesus being the Messiah that the Old Testament promised and its implications. Nevertheless now Jesus could build on their faith and commitment.
". . . Jesus' identity is progressively unveiled in three stages, though only from the standpoint of the reader. . . .
"The first stage in the progressive disclosure of Jesus' identity is the confession of Peter on behalf of the disciples (8:27-30)."203
8:30 Probably Jesus instructed the disciples to tell no one about Him for at least two reasons. First, such an announcement would have hindered His mission. Second, the disciples would not have been able to cope with the questions and opposition such an announcement would generate. They still held many popular misconceptions about Israel's Messiah that Jesus needed to correct. Jesus proceeded to continue preparing them so they could represent Him effectively.
"At the center of his Gospel Mark placed Peter's confession that Jesus is the Messiah. Up to this point the underlying question had been, Who is He?' After Peter's declaration on behalf of the Twelve, Mark's narrative is oriented toward the Cross and the Resurrection. From now on the underlying double question was, What kind of Messiah is He, and what does it mean to follow Him?' This crucial passage is the point to which the first half of the book leads and from which the second half proceeds."204
