Whether these three are integral parts of Penance?

❌ Objection 1 : It would seem that these three are not integral parts of Penance. For, as stated above (Question [84], Article [3]), Penance is ordained against sin. But sins of thought, word, and deed are the subjective and not integral parts of sin, because sin is predicated of each one of them. Therefore in Penance also, contrition in thought, confession in word, and satisfaction in deed are not integral parts.

❌ Objection 2 : Further, no integral part includes within itself another that is condivided with it. But contrition includes both confession and satisfaction in the purpose of amendment. Therefore they are not integral parts.

❌ Objection 3 : Further, a whole is composed of its integral parts, taken at the same time and equally, just as a line is made up of its parts. But such is not the case here. Therefore these are not integral parts of Penance.
