“To a Reformational Catholic, it’s blindingly obvious that there’s a billion-member Church of Jesus Christ centered in Rome. “

1/6th of the world's population as Christian? I don't think so.

Wiki lists Christians as 2.1B (which is around 1/3 world population), Muslims at 1.5B, Hindus at 1.2B, etc.

Huge disagreement as to how to count “believers.” Who qualifies? But that applies to all groups, not just Christians.
