Chapter 23 [X.]—The Pelagians Affirm that God in the Case of Abraham and Sarah Aroused Concupiscence as a Gift from Heaven.
He has much also to say, though to no purpose, concerning Abraham and Sarah, how they received a son according to the promise; and at last he mentions the word concupiscence. But he does not add the usual phrase, “of the flesh,” because this is the very thing which causes the shame. Whereas, on account of concupiscence there is sometimes a call for boasting, inasmuch as there is a concupiscence of the spirit against the flesh, 187 Gal. v. 17. and a concupiscence of wisdom.188 Wisd. vi. 21. The word in the Latin Bible in both cases is “concupiscentia.” Accordingly, he says: “Now you have certainly defined as naturally evil this concupiscence which is indispensable for fecundity; whence comes it, therefore, that it is aroused in aged men by the gift of Heaven? Make it clear then, if you can, that that belongs to the devil’s work, which you see is conferred by God as a gift.” He says this, just as if concupiscence of the flesh had been previously wanting in them, and as if God had bestowed it upon them. No doubt it was inherent in this body of death; that fecundity, however, was wanting of which God is the author; and this was actually given whensoever God willed to confer the gift. Be it, however, far from us to affirm, what he thought we meant to say, that Isaac was begotten without the heat of sexual union.
CAPUT X.
23. Dicit etiam iste multa frustra de Abraham et Sara, quomodo ex repromissione acceperint filium; et tandem concupiscentiam nominat: non tamen addit carnis, quia ipsa pudenda est. In concupiscentiae autem nomine aliquando gloriandum est: quia est et concupiscentia spiritus adversus carnem (Galat. V, 17), est et concupiscentia sapientiae (Sap. VI, 21). Ait ergo: «Certe hanc concupiscentiam sine qua nulla fecunditas est, malam naturaliter definisti: unde ergo per donum coeleste in senibus excitatur? Astrue jam hoc, si potes, ad opus diaboli pertinere, quod Deum vides conferre pro munere.» Ita hoc dicit, quasi concupiscentia carnis illis ante defuerit, et hanc eis donaverit Deus: quae procul dubio inerat in corpore mortis hujus; sed fecunditas defuit, cujus auctor est Deus, et ipsa donata est quando voluit Deus. Absit autem ut dicamus, quod nos putavit esse dicturos, Isaac sine concubitus calore generatum.
