Since science cannot provide any knowledge at all on or of anything, what is the biblical position on using fingerprints, DNA, etc. as evidence or witnesses in courts of law?

The biblical position is submission to government, and to accept a court or legal system that can never attain any truth about anything about reality. God himself revealed the legal system employed under Moses, but he never said that even by this system men would always discover the truth and uphold perfect justice. No, even under this system guilty men were frequently acquitted and innocent men were frequently condemned.

This is partly why God established such harsh penalties against perjury. The perjurer received the punishment that the one on trial, that the perjurer testified against, would have received. A perjurer who lies against a murder suspect, who is subsequently judged to be innocent, ought to be executed.

Follow the standard of evidence of any court that you operate under. The existing legal system is epistemologically arbitrary. It cannot, and from God’s perspective, it is never meant to maintain perfect – or perhaps even a little bit of – justice.

In the United States, it appears that hosts of innocent men are jailed or punished. Who are they? We do not know, and neither do the courts. And hosts of guilty men run rampant. The government helps prevent society from slipping into total chaos, but it is never intended to do God’s own work, not even a little bit. But God will render perfect justice to all and against all when he judges.

As a side note, this is why lawyers, although they think they are the best debaters in the world, are often some of the worst, and the easiest to defeat. This is because they are often stuck thinking in terms of the rules and standards of human court in their argumentation. But these rules are arbitrary and not rationally necessary.

Once they leave the court where they must debate an issue relative to the rules of truth and reason, it is like they are using basketball rules in a street fight – completely confused and helpless. I have no obligation to accept empirical and scientific evidences or the rules, standards, and procedures that he is accustomed to outside of a human court unless these are rationally supported.

Lawyers must learn to switch modes when arguing outside of court, and Christians should never be intimidated or show special respect to them in debate.
