Many Reformed still call non-justifying grace-persuasion faith’s specific act — against reason
So not a few Reformed doctors, seeing the force of the argument, deny that grace-persuasion (certainty that my sins are forgiven in Christ) is the act by which faith justifies.
Yet they still call that same persuasion justifying faith’s proper and specific act, and feature it in their definitions.
Le Blanc: that too leaves right reason — you cannot make a non-justifying fruit the specific differentia of justifying faith, or define saving faith by what only perfects it.

CV. Itaque non pauci Scholae Reformatae Doctores, vim rationis istius penetrantes, negant persuasionem per quam certo aliquis confidit peccata sibi esse per Christum condonata, actum illum esse cujus respectu fides nos justificare dicitur: licet eandem persuasionem dicant esse actum proprium & specificum fidei justificantis, & praecipuam ejus in fidei definitione mentionem faciant. Qua in re ipsi quoque a recta ratione discedunt. Nec enim ratio patitur, ut dicamus, actum qui non justificat esse proprium & specificum actum fidei justificantis, prout distinguitur a fide historica & non justificante: & ut salvificam fidem definiamus ab actu qui ex ea manat & enascitur quidem, sed tamen essentiam ejus non constituit, & solum ad ejus perfectionem spectat.
