Recently, J.D. Greear, pastor at The Summit Church wrote,
I don’t know of anywhere God spells out for us the ideal marginal tax rate, the proper number of refugees a compassionate country should take in, the godly posture toward gun control, whether health care should be nationalized, or exactly what our safety social net should include.
Pastor Greear is engaging in proof texting, something I'm sure he opposes. He slipped into it in a moment of weakness trying to make a point. But as Pastor Greear knows, there are no verses in the Bible that detail God's perspective on those issues. But he also knows that there are no verses that directly address many of the doctrines in our systematic theology books. The most obvious is the Trinity. No verse in the Bible contains the word "Trinity" or spells out the doctrine. Systematic theologians derive the main doctrines of Christianity by studying the whole Bible, comparing verses and distilling them. Political theology does the same.
What does systematic theology say about marginal tax rates? To answer that, theologians during the Reformation at the University of Salamanca asked first, what is the role of government? From the Bible, they determined that God created government to punish criminals (Romans 13), provide courts to settle disputes (Deuteronomy 17) and national defense.
