With Cæsarea Philippi as a backdrop we have a dramatic picture
The disciples evidently had no problem in understanding the designation “Son of Man” as Jesus’ personal reference to himself (cf. Mark 8:27). The usage here reminds the reader of Jesus’ humble earthly service (8:20; 10:23; 12:8, 32; 13:37, 41).
Would you have confessed like Peter did?
However, Peter’s Christological insight should not be construed as a sudden flash of insight, but was fundamentally grounded in his observation of Jesus’ performance in word and deed. As a matter of fact, Jesus’ entire ministry was performatively God’s revelation concerning the mystery associated with his person.
The claims Jesus made about Himself
Testimony of John the baptizer (Lk. 3:3-6; Jn. 1:19-34)
The miralces Jesus performed
Jesus was going throughout all Galilee, teaching in their synagogues and proclaiming the gospel of the kingdom, and healing every kind of disease and every kind of sickness among the people.
The news about Him spread throughout all Syria; and they brought to Him all who were ill, those suffering with various diseases and pains, demoniacs, epileptics, paralytics; and He healed them.
Large crowds followed Him from Galilee and the Decapolis and Jerusalem and Judea and from beyond the Jordan.
When evening came, after the sun had set, they began bringing to Him all who were ill and those who were demon-possessed.
And the whole city had gathered at the door.
And He healed many who were ill with various diseases, and cast out many demons; and He was not permitting the demons to speak, because they knew who He was.
