Some in Rome even hold, with most Reformed, that it was natural as opposed to supernatural
In fact, what we reported earlier shows that the Roman Church has its own teachers who side with most of the Reformed here. They hold that original righteousness was one of nature's gifts, not one of grace's, taking grace as the opposite of nature. On their view it was natural to the first man even in the sense that stands against "supernatural".
Latin
XLIV. Imo patet ex iis quae ante retulimus, in Ecclesia Romana non deesse, qui cum plerisque Reformatis doceant justitiam Originalem pertinuisse ad dona naturae, non gratiae, prout naturae opponitur: adeoque primo homini naturalem fuisse, quatenus naturale opponitur supernaturali.
