"Render unto Caesar" is the beginning of a phrase attributed to Jesus in the synoptic gospels, which reads in full, "Render unto Caesar the things that are Caesar's, and unto God the things that are God's" - Matthew 22:21

This phrase has become a widely quoted summary of the relationship between Christianity, secular government, and society. The original message, coming in response to a question of whether it was lawful for Jews to pay taxes to Caesar, gives rise to multiple possible interpretations about the circumstances under which it is desirable for Christians to submit to earthly authority.

Jesus responds to Pontius Pilate about the nature of his kingdom: "My kingdom is not of this world. If my kingdom were of this world, my servants would have been fighting, that I might not be delivered over to the Jews. But now (or 'as it is') my kingdom is not from the world" (John 18:36); i.e., his religious teachings were separate from earthly political activity. This reflects a traditional division in Christian thought by which state and church have separate spheres of influence.

it is stated that "...there is no power but of God, the powers that be are ordained of God" (Rom 13:1)

There will be a lot of passionate opinions. Mine is: Give to God what is God's. Give to Caesar what is Caesar's. If your going to play Caesar don't whinge and bitch if another Caesar wants to take your stuff.

This all depends on how much you think God is in control and how much you believe God can turn a King's heart.
