For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness;
All Commentaries on Romans 1:18 Go To Romans 1
Gennadius of Constantinople
Generally speaking there are two main types of sin—discord with God and discord with one’s neighbor. Paul mentions them both, putting discord with God first because it is the greater sin, and calling it “ungodliness.” He then mentions the second kind of discord, the one with one’s neighbor, calling it “wickedness.” He even states that our entire race has rightly come under judgment, saying that they have suppressed the truth in wickedness. Nor can they claim to be ignorant, for knowing the truth, they perverted it…. And outlining their sins, Paul lists the one against God first, saying that they had clear and plain knowledge about God because God had revealed himself to them. .
