I believe the answer is:
synod
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">church assembly</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for synod that I've seen before include "Clerical assembly" , "Council of clergy to discuss policy" , "Council of bishops" , "Ecclesiastical assembly" , "Church assembly" .)
