In reality, Christianity has no inherent connection at all with open-borders insanity and globalization. No less prominent a Christian than St. Thomas Aquinas expressed the mainstream Christian view when he said that “after his duties towards God, man owes most to his parents and his country. One’s duties towards one’s parents include one’s obligations towards one’s relatives, because these latter have sprung from [or are connected by ties of blood with] one’s parents…and the services due to one’s country have for their object all one’s fellow-countrymen and all the friends of one’s fatherland.” An open-borders globalist? Not quite.
It is telling that many of those who either cite the Gospel as the source for rejecting national loyalties and/or supporting immigration or invoke the Lord to justify the importation and exploitation of poor labourers are not themselves professing Christians. Of course, the absurdity of justifying the exploitation of labourers in the name of Christian fraternity ought to be obvious, but we live in dark times where even the simplest things are obscured. This quote also brings us back to the question of the relationship between Christianity and patriotism.
It has also never been clear to me where anyone came across the idea that orthodox Christianity endorses or encourages egalitarianism or rootless cosmopolitanism. (There have been many modern Christians who have understood their religion in this way, but their egalitarian and cosmopolitan views are typically matched by their departure from orthodoxy more generally.) The teachings in the Gospels and Epistles presuppose social hierarchy and patriarchal authority, and their authors literally cannot conceive of a world in which civic and family obligations are weak or non-existent, much less do they advocate for such a view. If Christianity is "universal" in that it is for the salvation of all, it nonetheless does not obliterate natural loyalties and affinities to particular places and peoples. Being willing to leave all your earthly relations for the sake of following God is a measure of the devotion the believer has and his desire to put God first--it does not abrogate his obligations to his kith and kin. Indeed, to be a good and faithful servant, the Christian must not only show mercy to those who seek it from him, but he must also discharge his duties to those to whom he is obliged and related. The Apostle exhorts: "But if any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel." (I Tim. 5:8)
