I believe the answer is:
papal
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">of the pontiff</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 papal that I've seen before include "Of the highest Vatican authority" , "Relating to the Pontiff" , "of Catholic high-up" , "Of the RC leader" , "Relating to the Pope" .)
