This question is concerned with the growth of global Christianity. The only problem that I have with it is that the answers may need to be updated every few years or every few decades, which makes this question different from theology-based questions.
A question based on a theological position/conviction may be more constant, unless the authorities in that religion change a doctrinal position or adapt a doctrine to modern times or re-interpret the same old doctrine in new light. Until then, the same old doctrine can be assumed to be true of the whole denomination.
It would be cool if there is a function that allows users to check which questions need to be updated once in a while. Maybe one question can be flagged as "need to be updated", and other users may come in and update it.
