Sinner cannot be both remitted and condignly punished
The same sinner cannot both receive remission and undergo sin’s full condign penalty.
Eternal death’s desert bars simultaneous salvation and exacted punishment in him alone.
Latin
IV. Sed impossibile erat homini peccatori simul peccatum remitti, & tamen illum pro merito puniri. Cum enim peccatum mortem & perditionem aeternam mereatur, fieri non potuit ut peccator servaretur, fieretque vitae & salutis particeps per divinam misericordiam, & tamen simul poenam peccato condignam subiret.
