“If you don’t hold from the eruv and you daven in a Shul where people who hold from the eruv bring in additional food for the kiddish can you eat of that food?”
popa_bar_abba – “No…I would say it has the din of meizid.”
popa_bar_abba – And will you drink wine that eruv carriers m’chalalei shabbos touch, and will you eat from their shchita or their cholent, can they lead the davening for you, and will you learn Torah from them or will you throw their s’farim into the trash?
