Learning of the death of Rabbi Lord Jonathan Sacks last night, I felt a spontaneous, visceral sense of loss. For years I have looked forward to his weekly reflection in the series Covenant and Conversation. Sacks has long been one of the few voices in British public life that carried real authority. He was firmly rooted in and expressive of his Jewish identity while remaining sincerely, lucidly, benevolently open to otherness. The Hesped read by his daughter Gila today is one of the most moving accounts I have ever heard of what it is to be a father.
