Aristotle wrote about kinds of love and he is the philosopher as Thomas Aquinas call him. One of kinds of love is philia. Without philia, or friendship-love, you cannot have society. Without society you cannot have culture or civilisation. But it is necceserry for this kind of philia, philia that is more than mere friendship, to exist there have to be sense of kindred. And you cannot have this sense in multicultural societies where there it is too easy to divide and conquer. Only idiots and tyrans are promulticulti (also marginal note, multiculti and other such shortenings like nazi are characteristic to jewish civilisation)
Now, did not Paul said that there is no greek or scythian or jew but are one? Yea, but he also said that there is no male and female. For all are one IN CHRIST. Not outside of it.
Now, did not Peter said that that we are all royal priesthood, choosen nation? Yea, but Israel, archtype of Church were of twelve tribes that even though they were of one blood were separate.
Now, did not we are all Adam stock? Yea, but when we wanted to mingle this stock and be of one culture, in days of Peleg, the God divided us defintevlly.
Now, do we not say in the creed "I belive in catholic, that means universal, church"? Yea, but universal does not mean unitarian.
Rember words of Tobias: 12 Son, be on your guard against prostitutes. Above all, marry a woman of our tribe, because we are descendants of the prophets. Do not marry anyone who is not related to us. Remember that Noah, Abraham, Isaac and Jacob, our earliest ancestors, all married relatives. God blessed them with children, and so their descendants will inherit the land of Israel. 13 Son, be loyal to your own relatives. Don't be too proud to marry one of them. Such pride leads to terrible frustration and ruin, just as laziness brings on severe poverty and causes starvation.
Patriotism is part of virtue of piety. But all racial or national hatered is contrary to spirit of charity.
