Interesting.Although I read a book recently that said Mary was actually a Judaic Princess, and was married to the Roman soldier who was Governor (or the son of the Governor) of Israel! One of those political alliances.
The book said that the reason Pilates found no fault in Jesus, was that he was actually the King of Israel by Roman law as well as the descendant of David in the Judaic tradition.
I wish I'd bought the book, cause then I'd know the name of it...
