Mixing linen/wool is shatnez ... and there are many tailors in the NY area that will test your clothes to ensure the fabric doesn't break this prohibition.
Circumcision ... well, you know that part.
Drinking blood, clean and unclean animals ... kashrut (keeping kosher), an integral part of it.
And if you were to see my DH & son's hair (& baby's once he's 3 & gets a haircut be'H
) you'd know that the haircut thing is still happening, too ...
Still alive & kickin' & full of meaning.
And Kama, about this parallel lives thing: I used to eat lunch with a guy who claimed he was Jesus. Looked like him, too (the white guy pictures of him, anyway
). Long hair, beard, beatific sort of personality. Wore a suit, too. When I worked in the WTC in the '80s I met him in the WTC plaza, & we'd regularly sit on the bench in front of the huge round globe sculpture for lunch (the sculpture that survived the destruction, btw, and is now a monument in Battery Park, but anyway.) Nice guy. I didn't refer to him by name, though. & never did find out his real name. Don't even know why he was at the WTC every day. He would just talk to me about G-d. Sweet guy.
The "chosen" concept is a difficult one, am going to find a link for you if I can. My understanding is more that the Jews chose to accept G-d's offer of the Torah. Jewish tradition tells of how G-d offered the Torah to nation after nation, and they all found a problem with it. "Don't steal? Can't do that, sorry." "Don't eat pork? Not for me." And then the Jewish people said, "Na'aseh v'nishmah,
" "we will do and we will listen," meaning we don't even know what's in there, yet we'll accept it from You sight unseen.
And the "chosen" concept has been used as an excuse for anti-Semitism and murder through the millenia, so maybe going there is ... well, difficult. "Chosen" means something different to the Jews than it does to non-Jews, so it needs clarifying, I think. I'll find a link.
