For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and deity; so that they are without excuse:
All Commentaries on Romans 1:20 Go To Romans 1
John Chrysostom
AD 407
Which also the prophet said, The heavens declare the glory of God. Psalm 19:1 For what will the Greeks (i.e. Heathen) say in that day? That we were ignorant of You? Did ye then not hear the heaven sending forth a voice by the sight, while the well-ordered harmony of all things spoke out more clearly than a trumpet? Did ye not see the hours of night and day abiding unmoved continually, the goodly order of winter, spring, and the other seasons remaining both sure and unmoved, the tractableness (εὐγνωμοσύνην) of the sea amid all its turbulence and waves? All things abiding in order and by their beauty and their grandeur, preaching aloud of the Creator? For all these things and more than these does Paul sum up in saying, The invisible things of Him from the creation of the world are clearly seen, being understood by the things which are made, even His eternal Power and Godhead; so that they are without excuse. And yet it is not for this God has made these things, even if this came of it. For it was not to bereave them of all excuse, that He set before them so great a system of teaching, but that they might come to know Him. But by not having recognized Him they deprived themselves of every excuse, and then to show how they are bereaved of excuse, he says.
