Mark 8:28

And they told him, saying, John the Baptist; and others, Elijah; but others, one of the prophets.

Significantly, the popular appraisal of Jesus' identity had been eroded and compromised by the savage campaign of vilification and misrepresentation which the religious leaders were so vigorously prosecuting against Jesus. From implications in all the synoptics, and from the most powerful assertions in John, it is clear that in Jesus' early contacts with the people he was readily hailed as the Messiah, or the Son of God, or King of Israel, as in the case of Nathaniel; but the evil campaign of the Pharisees had taken its toll, and at this point, the popular view extolled Christ merely as a prophet, or Elijah, Jeremiah, or John the Baptist, thus according him a noble place of honor but falling short of hailing him as the Son of God. Satan was pleased to have the Lord hailed as some great one, as long as he was not recognized as the Greatest One.

The episode recorded here provides the watershed of Mark's gospel; Cranfield stated that here "the second half of the gospel begins."[8] To this point, the great thrust of the gospel was directed to the establishment of our Lord as a divine person, reaching its glorious climax in Peter's confession of "the Christ." The second half of the gospel is the road to Calvary, marked here at the outset with the first announcement of his Passion and a dramatic shift of the Master's teaching to the phase of personal instructions for the apostles and away from teaching the multitudes.

This verse regarding the popular opinions of our Lord's identity has been seized upon by skeptics who have made it the basis of alleging a contradiction between John and the synoptics; but such allegations are illogical and irresponsible. The point in the synoptics is not that Jesus had never been publicly recognized as the Christ but that the counter-campaign of the religious hierarchy which was directed against the general recognition of his Messiahship had, to this point, been very successful. Their campaign against it proves that the recognition of Jesus as the Christ was sufficiently widespread to demand their campaign. See more on this in my Commentary on Matthew, p. 243.
