Let's be real here: this is an obvious interpolation. No one under extreme state persecution for his religion would call the state "God's servants". There's also the issue that none of the church fathers ever used it against Marcion, even though they very easily could have said, "Marcion, doesn't this mean the good God instituted the creator God?". Yet not a single one of his critics does, so these verses probably just didn't exist yet.

I think he probably did write, "1a Be subject to the higher authorities. 6 Give everyone what you owe them...", in the render unto Caesar sense. But the explanation is obviously an addition by a later hand.

On the other hand, Paul talks about "the end, when he should have annulled all rule and all authority and power" (1 Corinthians 15:24), and the new covenant "giving birth far above all rule and authority and power and every name that is named, not only in this age but also in the one to come" (Galatians 4:26).
