a system of government in which priests rule in the name of God or a god.
No debate or conflict over religion because everyone follows the same religion
Easier to govern when faith is tied with the government
If people start to question their faith or religion they might stop listening to the government
Church and state don't have much of a correlation so it is hard to bring the two together in places with many different religious beliefs.
"We do not want to live in a theocracy. We should maintain that barrier and government has no business telling someone what they ought to believe or how they should conduct their private lives." Robert Reich http://www.brainyquote.com/quotes/quotes/r/robertreic396292.html#hVhxUyRG9xjaYvbB.99
"Heard in full sound, the Gospels tell about the establishment of a theocracy, and portray what theocracy looks like with Jesus as king."
