The problem with Catholicism will always be that it has a singular head, and that singular head has been proven to be false quite a few times throughout history, most infamously (though not necessarily the worst offending example) would be Pope Alexander VI and the corruption he brought.

For such a person to be "chosen by God", at least how it used to be viewed, they should be above the sins that the Papacy has been known to commit.

So now hopefully you understand a small piece of why Catholicism is not always met in a very positive light.

I don't fault people on good faith; it's not like Catholicism promises X number of virgins for Y number of lives taken like a certain other religion.
