This is excellent.  It means that if the Universe is measurable, my original proposition holds -- "If the college of cardinals is actually a University, then any Pope it elects is infallible."

Can this be extended to other notions of "election", which do not require an ultrafilter for a class of cardinals to agree on a theology?
