EVA. – Progenitress of the human race. E. was created so that man might have “a help suitable for him” (Gen. 2:18–20). Adam (v.) called her E. (Heb. Ḥawmāh), from the verb ḥājāh, “to live”: hence “mother of the living” (Gen. 3:20).
So that man might become aware of his superiority over all other beings, God ordered the animals of paradise to approach Adam, who gave each of them a name corresponding to its nature, and realized that no animal species was like man; feeling himself alone, he desired a help suitable for him, or almost his own image, and God, to whose creative work he turned, granted his request. “Then the Lord God cast a deep sleep upon Adam” (Gen. 2:21; Heb. tardīnah), during which Adam was to perceive God’s intention: He formed the woman from one of his ribs or from the flesh of his side (ṣilāʾ). The anthropomorphic account means that God, by his omnipotent will, formed the woman from a part of man. The sacred writer, as the very form of the account in a historical book suggests and s. Paul confirms (I Cor., 11:6), intends to relate a real event. Metaphysically, it signifies the moral and social relations of the two sexes: man will love woman as a part of himself, and woman will lean upon her husband as upon her head, whom she loves and on whom she depends.

The reality of the historical event is also demanded by Adam’s words (Gen. 2:23); in the Hebrew text the name “woman” (ʿīfāh) is the feminine form of the name “man” (ʿīf), which the Vulgate rendered: “haec vocabitur virago quia de viro sumpta est”. Enlightened once again by God, Adam probably reveals the indissoluble and total bond of the spouses (Gen. 2:24; cf. Mt. 19:4–6).
To these considerations the Apostles and the Fathers add other reasons, such as: 1) so that man might be the origin of the entire human race and the unity of origin and species might be preserved (Mt. 19:4; Act. 17:26; cf. Gen. 3:20; 5:1–2); 2) so that the dignity and authority of man might be evident (I Cor. 11:7–9; I Tim. 2:13–14); 3) so that the union of Christ and the Church might be prefigured (Eph. 5:23–32; Io. 19:34).
After the original sin, of which E. was the initiator, God pronounced sentence against E.: “I will greatly multiply your toil and your pregnancy ... and yet you will feel drawn toward your husband, and he will rule over you” (Gen. 3:16); the punishment corresponds to pride and sensuality, essential elements of the fault. The condition of woman as wife has not changed, but as a natural consequence of sin, woman’s subjection will be harsh and painful (s. Tommaso, Sum. Theol., 2ᵃ-2ᵃᵉ, q. 164, a. 2, ad 1). In his goodness, God deigned to grant the first parents consolation by announcing the Redeemer, or new Adam, and also the co-redemptrix, or new E., as the Fathers have called Mary Most Holy (cf. s. Giustino, C. Tryph.: PG 6, 710; s. Ireneo, Adv. Haer., III, 22, 4: PG 5, 19, etc.).
VANGELO di III – An apocryphal work in use among the Nicolaitans, heretics of the apostolic period, according to s. Epifanio (Haer., 26, 2, 3, 5: PG 41, 334–35, 339). From the two brief citations that Epifanio makes of it, it appears that this apocryphon was Gnostic in character, composed in the literary form of an apocalypse. From a statement by Ippolito concerning E. (Philosoph., 5, 16), Harnack concludes that the Gospel of E. was also used by the Peratae.
