Jesus Christ's existence going on trial this week

The article reads:

Viterbo, Italy, north of Rome, is the venue where Rev. Enrico Righi is being sued by his childhood friend, atheist Luigi Cascioli, for deceiving people into thinking Jesus was an actual historical figure.

"This complaint does not wish to contest the freedom of Christians to profess their faith, sanctioned by [article] 19 of the Italian Constitution," says Cascioli, "but wishes to denounce the abuse that the Catholic Church commits by availing itself of its prestige in order to inculcate - as if being real and historical - facts that are really just inventions."

Many people believe in Jesus, because that's what they were taught to believe, by their parents and by the church. However, is there sufficient evidence, outside of the biblical text, to corroborate his existence? Can that evidence stand up to judicial scrutiny?

Many people simply say "you've got to have faith." Well, faith is a powerful weapon, and unfortunately, in this day and age, it's a cudgel wielded by a bunch of sanctimonious tyrants.
