The problem with Theonomists is that, not content with accepting Christ as King of a spiritual kingdom, they want to set up a Theocracy upon earth, believing quite incorrectly that that is the only way that God's law will be obeyed and honoured. Hence their political aspirations and their constant harping about the glorious "second reformation" in Scotland!
How this differs from the Roman Catholic view of church and state I have no idea, other than replacing the Pope for Synods!
