Pelagius — on Rom 5:14 (PELAGIUS'S COMMENTARY ON ROMANS)

“This may mean that as long as there was no one who distinguished between the righteous and the unrighteous, death imagined that it was Lord over all. Or else it may mean that death reigned not only over those who, like Adam, broke a commandment—like the sons of Noah who were ordered not to eat the life in the blood or the sons of Abraham, on whom circumcision was imposed—but over those who, lacking the commandment, showed contempt for the law of nature. Adam was a type of Christ either because he was made by God without sexual intercourse, just as Christ was born of a virgin by the aid of the Holy Spirit, or he was an antithetical type, that is, as Adam was the source of sin so Christ is the source of righteousness.”
