Tilenus: Rome slanders us as Pelagians; Adam's will was naturally upright but moved to act by grace, like a vine needing sun and rain
Similar things can be read in Tilenus: "The papists wickedly and slanderously pin the Pelagians' view on us, as though we held there were no supernatural gifts in the first man, when we expressly ascribe the theological virtues to him." (On Original Righteousness, thesis 38.)
A little earlier, explaining more precisely what the grace given to Adam consisted in, he says: "Adam's will had from nature the power to act righteously and holily; that it actually did so, and loved God above all things, came from its being moved effectively by grace.
"But a vine is not without a natural power to bear wine just because it needs outside help, such as sun, rain and tending, to bear it in fact. In the same way the uprightness of Adam's will and the good order (eutaxia) of his affections were still natural, even though in their actual exercise they were set to work and helped by moving grace."
Latin
XXXIX. Quibus similia apud Tilenum legere est. Criminose, inquit, & calumniose Pelagianorum sententiam nobis affingunt Pontificii, quasi nulla supernaturalia dona in primo homine fuisse contendamus, cum Theologicas virtutes ipsi tribuamus διαρρήδην. De justitia Originali thesi trigesima octava. Paulo ante vero distinctius explicans qua in re consisteret gratia Adamo collata, Ut a natura, inquit, id habebat voluntas Adami, ut posset juste & sancte operari, sic ut reapse operaretur, Deumque super omnia amaret, efficaciter movebatur a gratia. At quemadmodum vitis non propterea caret vi naturali ad proferendum vinum, quod externis illi opus est auxiliis, puta sole, pluvia & cultura, ut actu proferat, sic & in Adamo non ideo naturalis non fuit voluntatis rectitudo, & affectuum εὐταξία, licet in actu secundo gratiae moventis auxilio exercitaretur & adjuvaretur.
