Romans 1:32

who, knowing the ordinance of God, that they that practice such things are worthy of death, not only do the same, but also consent with them that practise them. [All were not guilty of all these sins, but each was guilty of some of them. Though many of these evils still exist in Christian lands, they do so in spite of Christianity; but then they existed because of idolatry. Lard observes that the Gentiles, starting with the knowledge of God, descended to the foolishness of idolatry. At this point God abandoned them, and they then began their second descent, and continued till they reached the very base and bottom of moral degradation, as indicated in the details given above. The Gentiles had traditions and laws, founded on original revelations, declaring these things sinful; and, though they knew that death resulted from sin, yet they not only defied God and persisted in their sins, but even failed to condemn them in others; yea, they encouraged each other to commit them. Such, then, was the helpless, hopeless state of the Gentiles. When they were justly condemned to death for unrighteousness, God revealed in his gospel a righteousness unto life that they might be saved.]
