I was brought up a strict southern baptist and have studied the bible extensively and in all my years I have yet to find the part that says the government should never be allowed to reflect the humanitarian values exemplified by the words of Jesus. When you heal the sick, feed the hungry, forgive your enemies and protect the downtrodden you practice true religion, the rest is just ritualistic mumbo-jumbo.
You studied the words but couldn't grasp the meanings. Jesus didn't preach a theocracy. His message was to change the inner man so your works reflected your spiritual awakening.
He clearly taught the division with the "give to Caesar that which is Caesar's" parable.
History proves what happens when the church unifies with the state. But I have a feeling your theocracy only includes what you deem important, everything else to be discarded.
