Thesis CXLII. He places this gift in the infusion of habits of grace and of the virtues, since the human mind, strengthened by those habits, elicits the act of conversion. On his view, then, efficacious grace is either habitual grace as it is infused, or the infusion itself, insofar as through that infused grace free choice elicits its own conversion, with God concurring in it at the same time.
Latin
CXLII. Hoc autem donum consistere vult in infusione habituum gratiae ac virtutum: quatenus per eos habitus mens hominis roborata elicit actum conversionis. Adeoque secundum ejus opinionem, gratia efficax aut est gratia habitualis, quum infunditur, aut ipsa ejus infusio: quatenus scilicet, per illam gratiam infusam liberum arbitrium elicit suam ipsius conversionem, Deo simul ad eam concurrente.
