First, she was not "cruelly persecuted by Muslims". Arabs owned her, & some of those families mistreated her, until she was 14, when Italian Catholics bought her. The Arab families made her convert to Islam.  All when slavery was legal.

Second, those who wrote the New Testament identified Pharisees, Saducees, & other groups primarily because those groups had been obstructing Jewish conversion to Christianity.

Third, a note re: these NCR Civil Comments:  the above comment by "Utilitas" was there for me to evaluate, after I posted a comment earlier.  I was pretty sure the Muslim smear was wrong, I knew the Jesus linkage was wrong, but on this smartphone, I didn't have access to another web page to check out the Muslim smear.  I was wrong to let it go as "sorta" ok.  I apologize to the NCR readers.
