You'd think Vatican News could spell Col
ombia correctly. It's not like there are only a few Catholics in that country.
Anyway, while I understand Pope Francis' point in a similar manner to Philip_B above (i.e., if we're going to have these international institutions, it ought not just be for show), I can't help but think of how disastrous it would be if his words were taken to heart when the Islamic bloc of the UN, headed particularly by Pakistan,
sought again and again to establish international blasphemy laws (read: international "make criticism of Islam, the Qur'an, and Muhammad a criminal offense" laws) via that same body. Those same laws can be an are used in the individual countries in which they are adopted to criminalize not just the Christian viewpoint on those topics, but to threaten the lives of various individual Christians, as in the Asia Bibi case in Pakistan of which I am sure Pope Francis is well aware. This is a matter over which I would think the Pope of the Roman Catholic Church would show some well-deserved concern.
So, no, I'm afraid I must respectfully disagree -- no one's duty as a Christian is to obey the United Nations or any other transnational body (the Hague, the EU, etc.) or even national body simply because it exists and is granted a certain degree of legitimacy. Let them prove their legitimacy by what they put forward and how they conduct themselves. Otherwise no.
