In his new book, Ask the Rab­bi: The Who, What, When, Where, Why and How of Being Jew­ish, Rab­bi Isaacs answers many com­mon ques­tions about the basics of Judaism. In chap­ters deal­ing with God, prayer, the Bible, hol­i­days, life-cycle events, dietary laws, Jew­ish denom­i­na­tions and anti-Semi­tism, he explains our beliefs, ethics and prac­tices. Using a ques­tion and answer for­mat, he tack­les dif­fi­cult sub­jects such as prov­ing the exis­tence of God, and what it means to be cho­sen. He also explains kashrut, talks about sex­u­al­i­ty, and dis­cuss­es a vari­ety of top­ics such as why Jews love Chi­nese food and why there are many Jew­ish physi­cians and come­di­ans but few Jew­ish ath­letes, and con­sid­ers Jew­ish-Chris­t­ian rela­tions. Those seek­ing greater depth on these sub­jects will want to con­sult sources such as the Ency­clo­pe­dia Judaica and the books of the late Rab­bi Hay­im Halevy Donin, but Rab­bi Isaacs’ book is a good intro­duc­to­ry source for home, school and syn­a­gogue libraries.
