Estius himself holds that unfallen man could not die, by the order God established
Estius himself, in the same place and in the next number, declares that he and many others hold a different view. He thinks we must say outright that while his first innocence stood man was unable to die.
It was not merely that man, persisting in obedience to God, would in fact not have died. The order of things God had once established necessarily required it, and it could not have been otherwise.
Latin
VIII. Ipse vero ibidem & numero sequenti testatur se, cum multis aliis, in diversa esse sententia. Nam omnino dicendum putat quod homo, stante prima innocentia, non potuit mori. Nec enim simpliciter futurum fuisse ut homo in obsequio Dei persistens non moreretur, sed etiam ordinem rerum a Deo semel institutum necessario istud exegisse, neque aliter potuisse fieri.
