Adam und Eva konnten nicht wissen, dass es böse ist, vom Baum zu essen, denn sie kannten ja noch nicht Gut und Böse. Also war der Ungehorsam unschuldig

1. Adam and Eve Had Full Knowledge and Understanding

STh I, q. 95, a. 1:

“Man was created with a perfect faculty of reason, in order to be able to judge his actions.”

Thomas Aquinas says: Man was from the very beginning a rational being, with intellectual clarity, moral judgment, and inner order.

Genesis 1:26–27: “In the Image of God”

“Then God said: Let us make man in our image, after our likeness. […] So God created man in his own image, in the image of God he created him.”

The image of God means for Thomas:

  • Reason

  • Free will

  • Capacity to know the truth and to love the good

Thomas says: The “image” consists above all in the spiritual nature of man, in reason and will (cf. STh I, q. 93, a. 4).

Adam was not an instinct-driven being, but intellectually capable of judging his actions—because he stood in the image of God.

Genesis 2:16–17: The Divine Command

“You may eat from all the trees of the garden. But from the tree of the knowledge of good and evil you shall not eat; for on the day you eat from it, you shall die.”

God speaks to Adam rationally and with a clear command. This presupposes:

  • Adam understands the language of God

  • Adam recognizes what a command is

  • Adam knows what obedience and death mean

Thomas sees here: A person who does not recognize what a prohibition is cannot receive a command. Therefore, it is clear: Adam was morally responsible.

Genesis 2:19–20: Adam Names the Animals

“The LORD God formed out of the ground all the animals of the field […] He brought them to the man to see what he would call them. […] The man gave names to all the livestock, all the birds, and all the animals of the field.”

Naming in the biblical world means dominion through knowledge. Only a rational being can recognize distinctions and classify them linguistically.

Thomas comments: The naming of the animals shows that Adam had an intellectual knowledge of nature, that is, a mind ordered toward God (STh I, q. 96, a. 1).

Genesis 3:8–10: Adam Hides from God

Man feels shame because he recognizes the moral breach.

He hides because he has consciously violated God’s command.

Thomas: This shows that conscience was active—that is, an inner knowledge of guilt, which is only possible if there was corresponding prior knowledge.

2. Adam’s Free Will Was Not Confused or Impaired

STh I, q. 95, a. 4:

“Man was endowed with perfect freedom of will, by which he could choose the good.”

There was no ignorance, no childish naivety. Adam acted freely, knowingly, and consciously. This makes his sin grave.

3. The Punishment Is Not Due to Lack of Knowledge, but Due to Pride

STh I, q. 99, a. 1 ad 2:

“Man wanted to judge for himself, independently of God, what is good and evil—this was the sin of pride.”

Thomas emphasizes: The “knowledge of good and evil” did not mean moral clarity, but the presumption to be judge of morality oneself.

4. The Sin Consisted in Disobedience Against a Clear Command of God

STh I-II, q. 71, a. 6:

“The first sin was a disobedience that arose from pride, because man rejected the divine order.”

Thomas says very clearly here:

The sin did not consist in the act itself (eating a fruit), but in the act of disobedience against the will of God.

5. Adam Had the Duty to Obey God for God’s Sake

STh II-II, q. 104, a. 2:

“To obey the divine will is a moral duty, even if the reason for the command is not fully understood.”

Adam had to obey God not because he understood the command, but because he knew it was God’s will.

Augustine of Hippo († 430)

Augustine is the main witness for the doctrine of original sin in the Western Church. In several works he shows:

“Adam had the gift of not sinning, but he did not use it.” De libero arbitrio, III

“The original sin was pride, which consisted in turning away from God—in the will to be independent.” De civitate Dei, XIV,13

Augustine explains that Adam and Eve acted willfully and knowingly against God’s command because they wanted to place their own will above the divine.

John Chrysostom († 407)

“Adam was not ignorant. He had received the command, he had understood it, he had explained it. Yet he did not obey.” Homiliae in Genesim, Homily 17

Chrysostom emphasizes that humans were able to keep the command—and yet broke it. Therefore, he was justly punished.

Catechism of the Catholic Church (1992)

“Man let trust in his Creator die in his heart.” CCC 397

“Through temptation, man let his heart be drawn in a false direction. He allowed himself to be seized by distrust of God.” CCC 398

The Catechism directly follows the line of Augustine and the Council of Trent: Adam and Eve were not innocent, but freely responsible.

Pope Pius XII – Encyclical Humani Generis (1950)

“The sin of the first parents is a real, historically accomplished act, through which original holiness was lost.”

The Church rejects any form of “mythical” or “symbolic” fall that could be based on ignorance. The fall was real, free, and culpable.

Gregory the Great († 604)

“They knew what was commanded of them. They had the choice. They listened to the serpent, not to the Creator.” Moralia in Job, Book 10

Gregory explains that the serpent’s cunning did not take away knowledge, but corrupted the will. The guilt lay in the free decision, not in lack of knowledge.

Der Satz der Schlange in Genesis 3,5 lautet:

„Gott weiß: Sobald ihr davon esst, gehen euch die Augen auf, und ihr werdet wie Gott, erkennen, was gut und böse ist.“

Das scheint zu widersprechen, dass Adam und Eva bereits wussten, was gut und böse ist. Doch das ist nur ein scheinbarer Widerspruch. Die katholische Theologie – vor allem Thomas von Aquin, Augustinus und die Kirchenväter – haben diesen Vers sehr präzise ausgelegt.

Was bedeutet „erkennen, was gut und böse ist“?

Es meint nicht: moralische Unterscheidungskraft bekommen.

Denn:

  • Adam und Eva konnten bereits moralisch urteilen.

  • Sie wussten: Gott hat es verboten.

  • Sie verstanden: Ungehorsam ist falsch.

  • Deshalb waren sie verantwortlich.

Es meint: Selbst entscheiden wollen, was gut und böse ist

Die Schlange schlägt nicht Erkenntnis, sondern Selbstherrschaft vor.

Sie sagt sinngemäß: „Ihr werdet wie Gott. Ihr entscheidet dann selbst, was gut und böse ist.“

Das ist kein Zuwachs an Weisheit, sondern der Stolz, an die Stelle Gottes zu treten.

Thomas sagt:

  • Die Vernunfterkenntnis war da.

  • Aber der Mensch wollte nicht mehr unter Gott stehen, sondern selbst Normgeber sein.

Biblisch bestätigt in Genesis 3,22:

„Siehe, der Mensch ist geworden wie einer von uns, indem er Gut und Böse erkennt…“

Das ist keine Bestätigung der Lüge der Schlange, sondern eine ironische Feststellung Gottes: Der Mensch hat sich erhoben, aber nicht wirklich Gott gleich geworden – er ist gefallen.

Why did Adam and Eve only realize they were naked after eating the forbidden fruit, even though they were naked before?

In Genesis 3:7 it says:

“Then the eyes of both of them were opened, and they realized they were naked.”

And before that, in Genesis 2:25, it says:

“The man and his wife were both naked, and they felt no shame.”

So what changed?

Why did they feel shame after the Fall—and what does “their eyes were opened” mean?

1. Before the Fall, nakedness was innocent

STh I, q. 99, a. 1 & II-II, q. 151, a. 4 ad 3

“Before sin, man was in a state of perfect subordination: the body obeyed the soul, the soul obeyed God.”

Adam and Eve had no disordered passions.

Their bodies were completely subject to their spirit—therefore, shame was unnecessary. They were naked but not ashamed, because they saw nothing in themselves that was against the order of reason.

2. After the Fall: Loss of inner order

Thomas, STh I-II, q. 85, a. 3

“Through sin, the rule of reason over the drives was broken.”

After the Fall, passions and desires arose in humans that had previously been ordered.

The first thing Adam and Eve felt was the sudden disorder within themselves—and the fear that the other might see this disorder.

That is why it says: “They realized they were naked”

not because they didn’t know it before, but because now they experienced their nakedness as a sign of inner brokenness.

Thomas summarizes it as follows:

“Shame did not come from the knowledge of nakedness itself, but from the awareness that the body was no longer under the obedience of reason. This shame is the fruit of guilt.” STh II-II, q. 151, a. 4 ad 3

3. Augustine confirms this

“They did not see something they had not seen before, but they were ashamed of what had become disordered through guilt.” De Civitate Dei, XIV,17

Their eyes were not opened in the sense of new knowledge, but in the sense of lost purity.

“Their eyes were opened” therefore means:

  • Not: new knowledge

  • But: Loss of grace → loss of inner peace → shame
