But I see Pope Francis having a greater impact in the long run. He hasn't strayed from Catholic theology but has emphasised it's more compassionate merits. I don't agree with his worldview, but he is an extremely potent ambassador for the worlds largest single religious denomination. I accept things about Catholicism can't change, but if he does what he says as well as telling others what to do I can only respect the man and how he handles his responsibility.
A man without fear is a fool, a man that succumbs to his fear is a coward and a brave man acknowledges fear yet presses on.
