What Did People Call Jesus During His Life?

We continue our look at the titles of Christ in the gospels as we anticipate our study of the infancy narratives. What did the term Son of Man mean? Why did Jesus use it and why wasn't it used later by the Church? Did Jesus actually refer to himself as the Son of God, or was that simply a title that was given to him by the Church later? In some Bibles, people address Jesus as "Lord," but in other translations, people address him as "sir." Why? Did anyone actually call Jesus "Lord" during his lifetime?
