Cap. VIII Arg. 4 Resp.: will to punish follows foresight final perseverance — not cause of negative reprobation
True: God wills to show wrath and vengeance on all the reprobate. But that will to inflict vengeance is not immediately joined to the negative reprobation or non-election we are disputing. It arises from foresighted intervention of final perseverance in sin — a state of all the reprobate foresighted by God as infallibly future as an event consequent on negative reprobation, not as an antecedent cause. So the argument is weak: God in reprobating also wills to punish them; therefore foresighted sin is the cause of negative reprobation.
Latin
Est igitur verum, Deum velle ostendere iram et vindictam in omnes reprobatos: sed haec voluntas vindictae inferendae cum reprobatione illa negativa sive non-electione, de qua disputamus, non est immediate conjuncta, sed exoritur ex praeviso interventu finalis perseverantiae in peccato: qui status omnium reproborum infallibiliter futurus praevidetur a Deo ut eventus consequens negativam reprobationem, non ut causa antecedens. Est igitur parum firma argumentatio, Deus reprobans homines, vult eosdem etiam punire, Ergo reprobationis negativae causa est peccatum praevisum.
