It's interesting that Christian history has a lot to do with taxation and tax collectors. Looks like St. Patrick had issues with it too.
To me, money, debt, and the government's role in property rights is a central issue in Christianity. This is not exactly Austrian, but my view is that government should do nothing other than enforce property rights, and money definition is an extension of property rights. National borders are an extension of property rights as well. "Give to Caesar that which is Caesar" is an issue of money. The State should define money and nothing else. It gets into trouble when it tries do do other things like wage wars and enforce cultureal biases.
