4 For he (government) is the minister of God to thee for good. But if thou do that which is evil, be afraid; for he beareth not the sword in vain: for he is the minister of God, a revenger to execute wrath upon him that doeth evil.
6 For for this cause pay ye tribute (taxes) also: for they are God's ministers, attending continually upon this very thing.
7 Render therefore to all their dues: tribute to whom tribute is due; custom to whom custom; fear to whom fear; honour to whom honour.
Romans 13, KJV
Nowhere in Romans does He suggest that government should legislate charity.
