My sermon for Erev Sukkot addresses a direct and painful collision in the Jewish calendar: the beginning of 'z’man simchateinu', the season of our joy, falls on the exact second anniversary of the October 7th atrocities. It explores how the sukkah itself, with its flimsy walls and lesson in vulnerability, will not let us hide from this echo. This year, those walls are a stark reminder of the vulnerability imposed on so many. The sermon grapples with how we can possibly celebrate in the face of this memory, the ongoing hostage crisis, and the fresh grief from the recent antisemitic attack in Manchester. The message redefines Sukkot's joy not as a distraction, but as an act of defiance, resilience, and sacred memory—a way to honour those who no longer can, by choosing to build, gather, and sing because we remember.
