Romans 1:19-20

Listen to this page

The context

Romans 1:19-20 sits inside the indictment that runs from verse 18 to the end of the chapter. Paul has just stated the letter's thesis — the gospel as God's power for salvation — and turns at once to wrath revealed against ungodliness. Verses 19 and 20 explain why that wrath is just.

The argument continues in verse 21 with humanity's failure to honor God or give thanks, then runs through idolatry and a list of vices, underlying the case Paul builds through chapter 3.

The words

Gnōston, "knowable," and phaneros, "manifest": what can be known, and what lies in plain view.

Kathoratai, "is clearly seen," compounds the verb for seeing with an intensive prefix, and is used of things visible to the eye. Paul does not say creation suggests God; he says God is seen in it. Nooumena, "understood," is a present passive participle of noeō, to perceive with the mind.

Poiēma, "what has been made," comes from poieō, to make — the word behind "poem." The creation is God's artifact, and artifacts disclose their maker.

Theiotēs, "divinity," denotes the quality of being divine — not the noun used in Colossians 2:9 for the fullness of deity. What is perceived here is God's divinity and power, not the whole of his triune life. Anapologētous, "without a defense," describes a defendant with nothing to say.

What this passage establishes

There is a genuine, universal knowledge of God available through what he has made, and it is sufficient to render humanity culpable for suppressing it. The passage grounds the justice of judgment; it does not describe a path to salvation.

What it does not establish

It does not say natural revelation saves anyone. Paul's purpose is to establish guilt, not to offer an alternative route to God. The letter insists elsewhere that faith comes by hearing, and the argument of chapters 1 through 3 closes doors rather than opening one.

It does not specify the content of the knowledge. Verse 20 names God's power and divinity. It does not claim that creation discloses the Trinity, the incarnation, or the gospel, and readings that find the whole creed written in the stars are importing material.

It does not answer the question of the unevangelized. Whether anyone is saved by responding to the light available is not addressed. The text establishes that the light is real and that failure to honor it is culpable; it does not say what God does with those who never hear.

How the church has read it

Calvin built his account of a natural sense of divinity on this passage while insisting that sin suppresses it. The First Vatican Council (1870) cited the same argument in defining that God can be known with certainty from created things by human reason. Barth objected sharply, reading Romans 1 as a description of perdition rather than a resource, and his exchange with Brunner turned partly on this text.
