Is Adam or Eve more culpable for original sin?
The Short answer is: Adam.
The first sin called the "Sin of Adam" not the "Sin of Adam and Eve"
for a reason. Even the Exsultet proclaims that it was Adam's sin
that gained Christ as Our Savior.
O certe necessárium Adæ peccátum, quod Christi morte delétum est!(O truly necessary sin of Adam, destroyed completely by the Death of
Let us take into consideration the following passages taken from
Scripture or the Catechism:
1.Like Adam, they [Israel] have broken the covenant— they were unfaithful to me there. (Hosea 6:7)
2.Therefore, just as sin entered the world through one man….death reigned from the time of Adam to the time of Moses, even over those who did not sin by breaking a command, as did Adam…. (Rom 5:12, 14)
3.For as in Adam all die, so in Christ all will be made alive. (1 Cor 15:22)
4.All men are implicated in Adam’s sin, as St. Paul affirms: “By one man’s disobedience many (that is, all men) were made sinners”: “sin came into the world through one man…. (CCC # 402)
5.Following St. Paul, the Church has always taught that the overwhelming misery which oppresses men and their inclination towards evil and death cannot be understood apart from their connection with Adam’s sin….(CCC # 403)
6.How did the sin of Adam become the sin of all his descendants? The whole human race is in Adam “as one body of one man”.293 By this “unity of the human race” all men are implicated in Adam’s sin, as all are implicated in Christ’s justice. (CCC # 404)
In Genesis, God specifically told Adam (not Eve) that the entire earth was cursed because Adam had allowed Eve to persuade him to eat of the fruit, and also that he would die (Genesis 3:17-19).
Even St. Thomas Aquinas states in his Summa that Adam was responsible for transmitting Original sin to the entire human race and not Eve:
The solution of this question is made clear by what has been said. For it has been stated that original sin is transmitted by the first parent in so far as he is the mover in the begetting of his children: wherefore it has been said that if anyone were begotten materially only, of human flesh, they would not contract original sin. Now it is evident that in the opinion of philosophers, the active principle of generation is from the father, while the mother provides the matter. Therefore original sin, is contracted, not from the mother, but from the father: so that, accordingly, if Eve, and not Adam, had sinned, their children would not contract original sin: whereas, if Adam, and not Eve, had sinned, they would contract it. - Whether if Eve, and not Adam, had sinned, their children would have contracted original sin?
