Cap. X Arg. II close: adversaries confess an inscrutable good pleasure in preparing/not preparing efficacious grace — that pleasure precedes forescience of faith accepted or grace finally rejected; they may not affirm the reverse
You see what the adversaries themselves confess. From that let us conclude: in preparing and not preparing efficacious grace there is a secret, inscrutable good pleasure of God. It does not follow from the forescience of faith and accepted grace in the elect, or from the forescience of unbelief and grace finally rejected in the reprobate — it comes before both. For it would be ridiculous to say that from the providence decree only sufficient grace is prepared for some, with certain forescience it will be rejected, and that from the reprobation decree efficacious grace — which no hard heart refuses — is denied them, and then to teach that this happens because God foresaw they would reject his grace and die in unbelief and pertinacity. Those who dare not deny the first ought not so confidently to have affirmed the second.
Latin
Videtis quid ipsi adversarii fateantur: ex quibus concludamus, esse in praeparanda et non praeparanda gratia efficaci arcanum quoddam et inscrutabile beneplacitum Dei, quod non sequitur praescientiam fidei et gratiae acceptatae in electis, ac praescientiam infidelitatis et gratiae finaliter rejectae in reprobatis, sed utriusque praescientiam antecedit. Ridiculus enim fuerit qui diceret, ex decreto providentiae praeparari aliquibus gratiam solummodo sufficientem, cum praescientia certa quod rejicietur, atque iisdem ex decreto reprobationis negari gratiam efficacem, quae a nullo duro corde respuitur, ac postea doceret hoc fieri quia Deus praevidebat hosce gratiam suam rejecturos et in sua infidelitate et pertinacia morituros. Qui igitur prius non audent negare, non debuerunt posterius tam confidenter affirmare.
