And once again I say - there can be no Christian theocracy until The Christ reigns on earth. It's a silly discussion these Leftists like to have, without any understanding. Besides, who told them to fear the coming wrath, anyway?
Well, that depends on whether the Jesus we worship is a guru, or Lord. A "guru" exerts influence over the inner/subjective/private/imaginary/spiritual realm. A Lord demands public fealty, in every zone of life.
For the record, the vanishing legacy of common law is explicitly theocratic, and assumes that a jury of 12 randomly selected "good men and true" who swear an oath to the God of the Bible, with their right hands on the Bible, to uphold the standard of justice found in the Bible, can be trusted to administer justice.
True, as Harold Berman demonstrates, common law has been systematically and deliberately supplanted over the last 150 years or so by statute law, the law of the lawyers, rather than the law of God. Rather than 10 commandments, and around 600 case law applications of those commandements in the Bible, we get a telephone book's worth of new lawyer-made laws every day taht all of us are theoretically obliged to obey. Rather like the Nazi and Soviet philosophy of law -- make enough of them to ensure that everyone is always guilty of something.
Jesus rules today, directly in answer to our prayers, and indirectly through fathers, pastors, and magistrates. Pre-1789 America was a confederation of 12 explicitly Christian nations, and one humanist republic.
