John Dominic Crossan states that it is historically certain that Jesus was baptised by John in the Jordan. In the Antiquities of the Jews (18.5. 2) 1st-century historian Flavius Josephus also wrote about John the Baptist and his eventual death in Perea.
Why did Jesus get baptized at the age of 30?
Additionally, Jesus was not baptized, as other accountable candidates were, for the remission of sins. His was an act of simple submissive obedience that had no motive beyond itself. … He began his official rabbinical ministry at age 30, as was the custom, by being baptized to “fulfil all righteousness.” (Matt. 3:15.)
Where did Jesus go after he was baptized?
After the baptism, the Synoptic gospels describe the temptation of Jesus, where Jesus withdrew to the Judean desert to fast for forty days and nights.
