Fellow Christians (8)
I believe the answer is:
brethren
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">fellow christians</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for brethren that I've seen before include "Siblings (archaic)" , "Brotherhood" , "Old plural of brother" , "like John and Charles Wesley, perhaps" , "Brothers; Plymouth -" .)
