After reading the link allodial posted (Jesus son of Julius Pantera), something curious struck me:

Whenever the term "bastard" is used to describe 'Jesus', within this post and others, it is the name "Jesus" that is used. However, the same party who espouses that "bastard" theory also sometimes writes the name 'Yehoshuah' in other commentary.

What is interesting is that the name 'Yehoshuah' is never used in conjunction with the "bastard" theory by said party. Makes one wonder regarding the obfuscation allodial wrote about.

The test is easy: will anyone disparage the real name of the anointed Christ and Son of God, born in Bethlehem as scripture prophesied, by calling him a bastard?

I would bet not.
