Uhm... Why christianity?
I understand that the movie is supposed to be based on a true story, and so I'm going to assume that the whole catholic stuff and the priests and all of that mattered only because people believed in them.
But the question that never left me once when I was watching this movie is, why christianity? If it happened in Africa in some village somewhere, would the rules of that land's people's religion apply instead? Or ancient Greek mythology? If they were going by simply picking christianity because it was the religion most people believe, then I may be wrong, but isn't it islam that has the most followers these days?
Like, how do people find it plausible for christianity and only christianity no doubts whatsoever to be the true religion?
