Kehillah in Corinth I 11:27-29

Orthodox Jewish Bible

²⁷ Therefore, whoever eats the Pesach matzoh or drinks the Kiddush Cup of [Rebbe, Melech HaMoshiach] Adoneinu unworthily will be guilty and answerable for the basar and the dahm of [Rebbe, Melech HaMoshiach] Adoneinu.

²⁸ But let a ben Adam apply cheshbon hanefesh to himself and in that manner let him eat of the Pesach matzoh and let him drink of the Pesach Kiddush Cup.

²⁹ For the one eating and drinking is the one eating and drinking mishpat to himself when not discerning the basar (body).
