If Donald Trump ever serves as a figure that I personally consider to be a Pope, Antipope, Pseudopope, or Funko Pope, then this market resolves Yes.

For ambiguous cases, this must be a new role invented explicitly or obviously for Trump; it's not enough to point out that some evangelical church has previousy said they consider him a prophet. The role must have a title and Trump must either formally fulfill or verbally accept the title. Once accepted, the title need only have one obligation that Trump fulfills before I resolve Yes. It can be a special prayer meeting that he attends as Pope, a special hat he gets to wear, or any other symbolic gesture beyond the title itself. 

Or, if Trump ever denounces the catholic church/current Pope while in Avignon, France, this market will imemediately resolve Yes. I will not bet in this market, but I will personally tell God what bets
