The earliest and most important sources of written information about Jesus are gospels.
The genre is peculiar to early Christianity, and its name gives a clue to its intention, for gospel' translates the Greek word ewangelion meaning 'good news'.
This word was rarely used in pre-Christian times, except in Roman political propaganda, usually with reference to an emperor.
To the extent that they aim to propagate a particular, exalted view of the person they describe, Christian gospels are also propaganda.
They tell their readers (or hearers) that Jesus was something special, and they expect them to respond accordingly.
