Cap. X Arg. X: Basil and Isa. xlvi. — when God wills he saves and none resists; those not effectually called lack that unfrustrable will to convert and save
Basil agrees, in an oration Peter the Deacon reports (De incarnatione et gratia 8): Give, Lord, strength and safeguard. Make good the evil you take; keep the good in goodness—for you can do all things, and none contradicts you. When you will, you save, and none resists you. Both learned it from the Prophet on the divine will (Isa. Xlvi. 10–11): The Lord of hosts has sworn: It shall be as I thought; as I planned in mind, so it shall happen. The Lord of hosts has decreed—and who can weaken it? From all this I infer: for those not called with an efficacious call, not made religious, not kept in faith and holy obedience—in a word, not actually saved—God lacked that unfrustrable will to convert them, make them religious and faithful, keep them in faith, and at last save them in fact.
Latin
Hisce consonat illud Basilii, in oratione quadam quae refertur a Petro Diacono, lib. De incarn. et grat. cap. 8. Dona, Domine, virtutem ac tutamentum. Malos, quos sumis, bonos facito; bonos in bonitate conservato: omnia enim potes, et non est qui contradicat tibi. Cum enim volueris, salvas, et non est qui resistat tibi. Uterque a Propheta hoc didicit, qui de voluntate divina ita nos instituit, Isa. xlvi. 10 et 11. Juravit Dominus exercituum, Si non ut putavi ita erit, et quomodo mente tractavi ita eveniet. Dominus exercituum decrevit, et quis poterit infirmare? Ex hisce omnibus infero, quod eos qui non vocantur vocatione efficaci, et qui religiosi non efficiuntur, qui non in fide et sancta obedientia conservantur; uno verbo, qui reapse non salvantur, defuisse Deo illam voluntatem et infrustrabilem eos convertendi, religiosos et fideles efficiendi, in fide conservandi, atque tandem de facto salvandi.
