Ames on 'able to work and not to work': true in one sense, false in the other
Ames teaches this plainly in his Bellarminus Enervatus. Explaining the sense in which man, roused by prevenient grace and helped by God, can act in such a way that he can also not act, he notes that 'can act and not act' may be read in two ways.
In the first reading, the power not to act exists in the same subject at the same time as grace and the help needed for acting; this sense, he says, is entirely true. In the second reading, grace and the help given for a particular act, together with the absence of that act or the contrary act, sometimes exist or can exist in the same subject at once; this sense, he says, is false.
Latin
XLV. Id expresse docet Amesius in Bellarmino Enervato. Nam explicans quo sensu homo per praevenientem gratiam excitatus & a Deo adjutus, ita valeat operari, ut possit etiam non operari, observat istud posse operari & non operari, posse dupliciter exponi: primo ut sensus sit, quod potentia ad non operandum sit simul in eodem subjecto cum gratia, & auxilio quod requiritur ad operandum, & hunc sensum dicit esse verissimum. Secundo modo dicta verba sic intelligi posse, ut sensus sit quod gratia, & auxilium ad talem operationem particularem datum, & carentia talis actus, seu actus contrarius aliquando simul sint, aut esse possint in eodem subjecto: quem sensum dicit esse falsum.
