I do admire the integrity and insight of Rabbi David Small, who somehow is still in his position as rabbi in the Conservative (compromise) "Temple" in the small town of Barnard's Crossing, near Boston, Mass. I'm also thankful to the Almighty that he is Jewish and thus never had any influence on the CDF (modern Catholic equivalent of the Inquisition).
Harry Kemelman managed to integrate much Jewish thought (and almost Jesuit casuistry- not a Catholic monopoly, or innovation, apparently) into classic detective stories. This is "New England" before everyone owned guns (stated, firmly, in previous book), largely unaware of the world outside- even of most of the USA, let alone the rest of that continent...Barnard's Crossing is however exceptional in that it is possible for Catholics and Jews to be accepted as almost human (you have to be born there, or you're a migrant!). No chance of election to the equivalent of the burgh council, unless you're at least third generation native. This would be no place for the Scottish diaspora- the local non-Catholic Christians are decidedly "Episcopalian" with all the condescension of the ruling Anglo-Saxon hegemony!
The Rabbi has always been clear: Judaism does not mean faith - it does not require and would even deny the existence of the Almighty, being Jewish is an ethnicity (like I'm Scottish), Judaism is only a system of behaviour, but only for some descendants of Abraham (poor old Ishmael!) nothing more, and it is not even necessary or even desirable, to adhere to those norms. (Seems weird to me, being Catholic, something that influences me 24/7)
Usually his opponents are infinitely less likeable- totally stereotypical Americans - money-mad, crafty, greedy, intolerant, egotistical- but maybe he needs to get out more - except he can't - there are few houses he can accept food in ( not kosher), but still he picks and chooses which laws to obey...
