The Biblical conception of ethnicity has been the standard model of human social organization since ancient times. Nations arise from extended families connected by common genetic heritage.
GENETICS, ETHNICITY, AND FAMILY
Ancestry.com sells its DNA tests by advertising its ability to uncover ethnicity:
“Discover the family story your DNA can tell. Uncover your ethnic mix, discover distant relatives, and find new details about your unique family history with a simple DNA test. When your results arrive, you’ll see a breakdown of your ethnicity—and it may contain a few surprises. Then, you can start learning more about the places where your family story began… ‘ProGenealogists recommends Ancestry DNA as an indispensable tool for family history discoveries.’” Genetically speaking, ethnicity is merely extended family. The ability to “discover distant relatives” using DNA testing is only possible because distant relatives have common ancestors and share common genetic lineage. A DNA test cannot find cultural, religious, or linguistic connections, but it can uncover family history.
Influential paleo-conservative commentator Steve Sailor once observed that ethnicity is equivalent to extended family:
“Now the crucial step is [to] point out that the reason extended families provide such perfect analogies for races is because they are actually the same thing. A RACE IS SIMPLY AN EXTREMELY EXTENDED FAMILY.” What are the implications of this connection?
Twenty-first century Americans tend to downplay their ethnic identity. They claim their ancestry does not matter, and that they do not favor members of their own ethnicity over members of another ethnicity. In the minds of most Americans, ethnic bias is “racism,” and constitutes a category of thought crime.
This line of thinking, however, cannot be reconciled with the genetic reality of ethnicity. If one’s ethnic cousins are family members then one has an obligation to favor them over strangers who are not closely related.
Ethnic loyalty has a positive correlation with shared genetics. In other words, the more closely two people are related the more they owe one another allegiance. There are non-kin forms of allegiance (friendship, authority, religious, marital, etc.), but a certain form of allegiance is owed based upon genetic connection.
THE BIBLE AND ETHNIC FAMILY
A father cannot merely abandon his child. He has an obligation to his offspring due to the genetic link he shares with them. Jesus spoke of a genetic loyalty that obligated children to take care of their aging parents.  Paul said that a Christian who did not provide for his family was worse than an infidel.  Under the Mosaic Law, brothers had to take their sibling’s wives and produce an heir if they died childless. 
Outside individual family units, God organized Israel through tribes.  Tribes were groups of people more closely related than the broader ethnic group. Rather than merely being connected by a common ancestry with Jacob, the members of a tribe were united by descent from one of his twelve sons. These tribes of extended families inherited specific land within Palestine.
Beyond the tribe, God established ethnic identity. The Children of Israel were united by common linage to Abraham, Isaac, and Jacob. They were literally the children of these patriarchs.
The Israelites owed more loyalty to their fellow Israelites than to ethnic outsiders. Despite lacking a personal relationship with most of their fellow Hebrews, they often participated in war to defend their co-ethnic’s land, lives, and freedom. During the conquest of Canaan, all of the tribes fought together to conquer land for each individual tribe.
Every Israelite owed special allegiance to their family, tribe, and ethnicity. All of these allegiances were owed because of the genetic connection that formed them.
MODERN CHRISTIAN HYPOCRISY
Modern American Christians love to disavow any allegiance to their ethnicity, but they refuse to disavow traditional nuclear family. They claim to be defenders of “family values” and “intact families,” but they fail to see the hypocrisy in their unholy alliance with the “civil rights” agitators who inflict incredible damage on the extended ethnic families God has given us.
Conservative American Christians fail to understand the connection between the breakup of the family, LGBT “marriage,” and the Civil Rights movement of the 1960s. Their shocked when agitators change the definition of “marriage,” but never consider their own guilt in changing the definition of “nation” and “ethnicity.” They have destroyed the connection between citizenship and ethnic identity, but their perplexed when Cultural Marxists destroy the connection between family, gender, and child birth.
American Christians want to claim authority from the Bible when it suits their cultural agenda, but when it comes to acknowledging the Bible’s teachings on ethnicity and identity they would rather side with the liberals. The majority are too cowardly or ignorant to bravely face accusations of “racism” to defend God’s truth.
The concept of “racism” and ethnic bias being connected to “hate” is not rooted in logic. The connection made between them is part of a broader liberal agenda to destroy the Western family. Favoritism towards one’s extended family is familial love.

EXTRACT: “Let me pause to suggest some terminology. ‘Race’ is often used very broadly – ‘the human race’ vs. ‘the Irish race.’ Similarly, ‘family’ is sometimes used very broadly: ‘the human family’ or ‘the family of man.’ This vagueness can be salutary because it shows that there are no real hard and fast boundaries between races and families.”
 Mark 7:9-13: “And he said to them, ‘You have a fine way of are rejecting the commandment of God in order to establish your tradition! 10 For Moses said, ‘Honor your father and your mother’; and, ‘Whoever reviles father or mother must surely die.’ But you say, ‘If a man tells his father or his mother, ‘Whatever you would have gained from me is Corban”’ (that is, given to God) then you no longer permit him to do anything for his father or mother, thus making void the word of God by your tradition that you have handed down. And many such things you do.’” (ESV)
 I Timothy 5:8: “But if anyone does not provide for his relatives, and especially for members of his household, he has denied the faith and is worse than an unbeliever.” (ESV)
 Matthew 22:24-27: “‘Teacher, Moses said, ‘If a man dies having no children, his brother must marry the widow and raise up offspring for his brother.’ Now there were seven brothers among us. The first married and died, and having no offspring left his wife to his brother. So too the second and third, down to the seventh. After them all, the woman died.’” (ESV)
 Numbers 2:1-5: “The Lord spoke to Moses and Aaron, saying, ‘The people of Israel shall camp each by his own standard, with the banners of their fathers’ houses. They shall camp facing the tent of meeting on every side. Those to camp on the east side toward the sunrise shall be of the standard of the camp of Judah by their companies, the chief of the people of Judah being Nahshon the son of Amminadab, his company as listed being 74,600. Those to camp next to him shall be the tribe of Issachar, the chief of the people of Issachar being Nethanel the son of Zuar’” (ESV).
