Kehillah in Corinth I 11:17-19

Orthodox Jewish Bible

¹⁷ But in giving the divrei Torah that follows I give no commendation [11:2], because when you assemble as the shul of Moshiach, it is not for the better that you assemble, but for the worse.

¹⁸ Ershtins (first of all), indeed when you come together as the kehillah [SHEMOT 12:6] (I hear) there exist machlokot (divisions 1:10) and schisms among you, and partly I believe it.

¹⁹ For it is necessary also for kitot (sects) of minut (heresy), of kefirah (heresy, denial) to be among you that also the approved ones may become manifest among you [DEVARIM 13:3].
