Cap. II Sol. Arg. 5: will to save tied to will to teach — God did not teach all
This divine will for the salvation of all men must be read with the will joined to it — the will to teach all men. Paul binds them: God wills all to be saved and to come to the knowledge of the truth (1 Timothy 2:4). Yet it is certain from God's word and from history that he has not willed to teach all, or to lead every person one by one to saving truth. Romans 10:14: how will they call on him in whom they have not believed? how believe without hearing? how hear without a preacher? how preach unless they are sent? In past generations God let the nations walk in their own ways (Acts 14:16) and gave knowledge of the truth to Israel alone. After Christ's coming the light did not at once shine on all by his will: for a time the apostles were barred from the Gentile road (Matthew 10:5), and later forbidden to preach in Asia (Acts 16:6). Come to our own age: how many nations found in the New World have for centuries not felt even a breath of saving truth? Can God be said to have willed them to know the truth when he would not send them heralds of it? See Prosper of Aquitaine on the Gallic chapters (Response 4 and Sentence 4). If they take Paul to mean that God, as far as in him lies, wills to give every fallen child of Adam saving knowledge and salvation itself for Christ's sake, you must either call their reading a clear error or confess weakness in the divine will — for the one who wills, and can, acts.
Latin
Voluntas haec Divina de salute omnium hominum, non aliter concipienda, quam illa quae conjungitur de eruditione omnium hominum. Connectuntur enim ab Apostolo; Deus vult omnes salvos fieri, & ad agnitionem veritatis venire. Est autem certissimum, tum ex verbo Dei, tum ex ipso eventu, Deum non habuisse aut habere voluntatem erudiendi omnes, sive perducendi omnes singulatim ad salutiferae veritatis cognitionem: Rom. x. 14. Quomodo invocabunt eum in quem non crediderint? quomodo autem credent ei de quo non audierint? quomodo audient absque praedicante? aut quomodo praedicabunt si non mittantur? At Deus praeteritis generationibus dimisit omnes gentes suis ipsarum viis incedere; Act. xiv. 16. Ac veritatis agnitionem soli nationi Judaeorum concessit. Post Christi adventum lux veritatis non statim omnibus ex voluntate Dei affulsit. Ad tempus prohibiti sunt Apostoli in viam gentium abire, Matth. x. 5. Aliquanto post vetiti sunt etiam ne praedicarent verbum in Asia, Actor. xvi. 6. Atque ut ad nostra secula descendamus, quot nationes in Novo orbe detectas habemus, ad quas salutiferae veritatis per multa secula ne tenuissima quidem aura pervenit? An dici potest Deus voluisse illos ad agnitionem veritatis venire, ad quos noluit praecones veritatis mittere? Videte Prosperum Aquitanicum, ad Capit. Gall. Respons. 4. & Sent. 4. Si itaque sic intelligunt verba Apostoli, ut sentiant Deum, quantum in se est, velle omnes & singulos mortales in Adamo lapsos propter Christum donare salutiferae veritatis cognitione & ipsa salute, aut in hac illorum sententia manifestum errorem, aut in Divina voluntate manifestam infirmitatem agnoscere est necesse; nam volens potens operatur.
