Rabbi Mordechai and his American-born wife Blima are parents of nine children, aged between one and 16. As members of the Hasidic Jewish movement, Chabad, they live a strictly Orthodox Jewish lifestyle at home - adhering scrupulously to ancient rules covering everything from diet to marital relations. But theirs isn't an inward-looking or isolated life: Mordechai ministers to a congregation of 800 families across the community with various levels of observance.
