Is dating your second cousin wrong
In the very early days of humanity, there were a limited number of human beings.
As a result, marriage between close relatives was often necessary.
Unfortunately, many times the person who claims that something is "a sin against God," or that an individual will "burn in Hell" for his actions or lifestyle have no clear understanding of what Scripture says on the subject.
Perhaps even more unfortunate is that many preachers, priests, and theologians have also allowed society to cloud their judgment on the issue, rather than to study what the Bible has to say on the subject for themselves.
This is true both of devout Christians as well as those who may have some vague, indiscernible root in the Christian faith.
English is sometimes irritatingly vague when it comes to kinship terminology, even within fairly close family relationships.
I can’t tell (without more context) if your brother-in-law is your sister’s husband or your husband’s brother.
Therefore, it was safe for close relatives to marry and have children.
There was little risk of genetic abnormalities in their children.
