Sorry about the delayed reaction but I have just been rereading these posts and your description of yourself and it reminded me of a good Jewish friend of mine who answered the same description. He agreed to be the best man at my wedding until he realised it would clash with Yom Kippur. He explained how important it was to keep the fast, "For my inheritance". He gave the same explanation when he volunteered to spend a year in an Israeli Kibbutz. I never knew if he was joking or not.There's a Yiddish expression - Shabbos goy. That s a non Jew who can perform some work prohibited on Shabbat.
I'm at the humanistic end of the 'faith' - I'm pretty secular, but respect ancestry, identity and some traditions but not the 'detail' so I ve never quite got the difference between using someone to do it and doing it myself. However what you say [and do] means that you are respected, trusted and I shake your hand for the help you give my [distant] cousins.
I also have a neighbour who worked for many years for "Old Man Schleider" no disrespect intended but that was what everybody called him. My neighbour said he was never allowed to work on the Jewish Sabbath except in an emergency but Sundays were all right.
