The Jesus We Missed: The Surprising Truth About the Humanity of Christ by Patrick Henry Reardon (excerpts from chapter 5):
By the time the four gospels were composed, it is safe to say that probably nobody was certain of the actual sequence of all the events in Jesus’ life. It was not thought to be important. Other considerations, consequently, determined the order in which these stories were handed down in the church’s catechesis (based on the apostles’ preaching) and later recorded (in the four gospels).
…When the Spirit descended on Jesus at his baptism, something changed. It was an event, with a before and after. Of course, Jesus already was conscious of himself as God’s Son (cf. Luke 2:49), but this new experience at his baptism was decisive; it created, in his life, a then and now. He grew, he increased, through this experience; and, when he went through it, his family and friends recognized that something truly unique had happened to him. Indeed, they were disturbed by his new behavior.
…No one else in the world could read the prophecy as Jesus did, claiming complete and internal ownership of it. Luke implies that his hearers in the synagogue sensed the difference, inasmuch as “the eyes of all who were in the synagogue were fixed on him.”
…Like the preceding sign, this one involves no physical contact by Jesus. But we do detect another common trait appearing in both signs; namely, obedience to a command: “Fill the water jars with water” (John 2:7) and “Go your way” (4:50). Disobedience to these commands, we presume, would mean no miracle! Exactly the same traits—subtlety and obedience to command—characterize the third sign described by John, the healing of the paralytic at the pool of Bethesda.
