Whether Penance is fittingly divided into penance before Baptism, penance for mortal sins, and penance for venial sins?

❌ Objection 1 : It would seem that penance is unfittingly divided into penance before Baptism, penance for mortal, and penance for venial sins. For Penance is the second plank after shipwreck, as stated above (Question [84], Article [6]), while Baptism is the first. Therefore that which precedes Baptism should not be called a species of penance.

❌ Objection 2 : Further, that which can destroy the greater, can destroy the lesser. Now mortal sin is greater than venial; and penance which regards mortal sins regards also venial sins. Therefore they should not be considered as different species of penance.

❌ Objection 3 : Further, just as after Baptism man commits venial and mortal sins, so does he before Baptism. If therefore penance for venial sins is distinct from penance for mortal sins after Baptism, in like manner they should be distinguished before Baptism. Therefore penance is not fittingly divided into these species.
