Romans 13:1-7 is a controversial section of Paul’s letters, because it implicitly contradicts the teachings of Christ if you stop in verse 1. If you look at the whole context of the passage, he seems to be placing conditions on verse 1 that would exclude pretty much every government in history.
As usual, it’s best to refer to Christ’s words in the gospels when you’re trying to understand his teachings. He preached nonviolent resistance, turning the other cheek, forbade oath-taking.
He did not say capital punishment is cool.
